Need help with trigger comp err
i'm new to forms and triggers. I am trying to do a simple "select into" from the "previous" record so I can see what was the value of a column was and bump it up by one. The code for a post_text_item trigger is:
select
anum
from
x
where
x.pageid = :pageid;
the gist of the error is that the compile acts like it never heard of table "x", even though the form is built on table "x"! the err is - PDE-PSD001 - Could not resolve ref to unk program unit while loading block ...
any thoughts??
thanks in advance,
Burt

actually -
if the table I mention in the trigger contains an Ordsys.Ordimage column, the trigger blows. I guess the little procedure builder guy cant deal with the intermedia stuff too well/at all. I created a view from the table with the image, but didn't include the image in the view. I referenced the view in the trigger and everything went just fine.
thanks for your input

Need help with trigger/new at pl/sql
I would appreciate any help as I am new to PL/SQL and have run out of ideas.
I am trying to write a trigger that when a user inserts a row into a table that records an ID, a clinic, and user initials, a second table is updated with that ID in the next available "slot" for that clinic.
I wrote a procedure that does execute successfully with ID, user initials, and clinic hardcoded. I cannot create a trigger using the fields from the 1st table instead of the hardcoded values that compiles without errors.
The tables in question are in another schema, but I have all priviledges on that schema.
I have tried referencing the fields from table 1 in every way I can think of:
1) :new.<field from table 1> and got:
ORA-04082: NEW or OLD references not allowed in table level triggers
2) :<field from table 1> and got
PLS-00049: bad bind variable '<field name>'
3) <field from table 1> , <table>.<field from table 1>, <schema>.<table>.<field from table> and got
5/38 PL/SQL: ORA-00904: "N106CLINIC": invalid identifier
14/44 PL/SQL: ORA-00904: "N106CLINIC": invalid identifier
and
5/38 PL/SQL: ORA-00904: "N106"."N106CLINIC": invalid identifier
14/44 PL/SQL: ORA-00904: "N106"."N106CLINIC": invalid identifier
and
5/38 PL/SQL: ORA-00904: "CCRN"."N106"."N106CLINIC": invalid identifier
14/44 PL/SQL: ORA-00904: "CCRN"."N106"."N106CLINIC": invalid identifier
in addition to "SQL statement ignored".
It does complain only about n106clinic, even though other fields referenced from the first table are n106id and n106init; n106clinic IS a valid field name in the n106 table...maybe this is just a compiler peculiarity.
Here is the code for the trigger. N106 is the table where the user inserts a row and RAMBCYL is the table to be updated. CCRN is the schema that owns the two tables.
create or replace trigger ccrn.aocylrand
after insert
on ccrn.n106
declare l_accno number;
begin
select rambcyl.accno into l_accno
from ccrn.rambcyl rambcyl
where rambcyl.clinic=n106clinic and
rambcyl.accno = (select min(r.accno)
from ccrn.rambcyl r
where r.id is null
and r.clinic = n106clinic);
update ccrn.rambcyl set id =n106id,
randdt = sysdate,
staff=n106init
where ccrn.rambcyl.accno = l_accno and
ccrn.rambcyl.clinic = n106clinic;
end aocylrand;
Thanks, HelenYou cannot refer to the :old or :new column values in a statement level trigger, only in row-level triggers. I would suggest the following which does the update in a single statement:
create or replace trigger ccrn.aocylrand
after insert
on ccrn.n106
for each row -- specifies a row-level trigger
begin
update ccrn.rambcyl r1
set id = :new.n106id,
randdt = sysdate,
staff = :new.n106init
where clinic = :new.n106clinic
and accno = (select min(r2.accno)
from ccrn.rambcyl r2
where r2.id is null
and r2.clinic = r1.clinic);
end aocylrand; -

Need Help With File Matching Records
I need help with my file matching program.
Here is how it suppose to work: FileMatch class should contain methods to read oldmast.txt and trans.txt. When a match occurs (i.e., records with the same account number appear in both the master file and the transaction file), add the dollar amount in the transaction record to the current balance in the master record, and write the "newmast.txt" record. (Assume that purchases are indicated by positive amounts in the transaction file and payments by negative amounts.)
When there is a master record for a particular account, but no corresponding transaction record, merely write the master record to "newmast.txt". When there is a transaction record, but no corresponding master record, print to a log file the message "Unmatched transaction record for account number ..." (fill in the account number from the transaction record). The log file should be a text file named "log.txt".
Here is my following program code:

I am not sure what is wrong with my code above to make my results different from the correct results.
Much help is appreciated. Please help.From the output, it looks like one problem is just formatting -- apparently you're including a newline in log entries and not using tabs for the newmast output file.
As to why the numbers are off -- just from glancing over it, it appears that the problem is when you add multiple transaction values. Since account.combine() is so simple, I suspect that you're either adding creating transaction objects incorrectly or not creating them when you should be.
Create test input data that isolates a single case of this (e.g., just the Mary Smith case), and then running your program in a debugger or adding debugging code to the add/combine method, so you can see what's happening in detail.
Also I'd recommend reconsidering your design. It's a red flag if a class has a name with "Create" in it. Classes represent bundles of independant state and transformations on that state, not things to do. -

<h1>For Students</h1>
<p>The University of Massachusetts Amherst is leading a Commonwealth Alliance for Information Technology Education (CAITE) to design and carry out comprehensive programs that address under representation in information technology (IT) education and the workforce. CAITE will focus on women and minorities in groups that are underrepresented in the Massachusetts innovation economy; that is, economically, academically, and socially disadvantaged residents.</p>
<p>The project will pilot a series of outreach programs supported by educational pathways in three regions (one rural, one suburban, and one urban). The project will include work with high school teachers, staff, and counselors. CAITE will identify best practices and disseminate, deploy, extend and institutionalize these best practices statewide and nationally.</p>
<p>Community colleges are the centerpiece of CAITE because of the central role they play in reaching out to underserved populations and in serving as a gateway to careers and further higher education.</p>
<p>This project will build a broad alliance built on its leadership in and partnership with the Commonwealth Information Technology Initiative (CITI), the Boston Area Advanced Technological Education Center (BATEC), regional Louis Stokes Alliances and NSF EGEP programs, and other partnerships and initiatives focused on information technology education and STEM pipeline issues</p>

Need help with Berkeley XML DB Performance
We need help with maximizing performance of our use of Berkeley XML DB. I am filling most of the 29 part question as listed by Oracle's BDB team.
Berkeley DB XML Performance Questionnaire
1. Describe the Performance area that you are measuring? What is the
current performance? What are your performance goals you hope to
achieve?
We are measuring the performance while loading a document during
web application startup. It is currently taking 10-12 seconds when
only one user is on the system. We are trying to do some testing to
get the load time when several users are on the system.
We would like the load time to be 5 seconds or less.
2. What Berkeley DB XML Version? Any optional configuration flags
specified? Are you running with any special patches? Please specify?
dbxml 2.4.13. No special patches.
3. What Berkeley DB Version? Any optional configuration flags
specified? Are you running with any special patches? Please Specify.
bdb 4.6.21. No special patches.
4. Processor name, speed and chipset?
Intel Xeon CPU 5150 2.66GHz
5. Operating System and Version?
Red Hat Enterprise Linux Relase 4 Update 6
6. Disk Drive Type and speed?
Don't have that information
7. File System Type? (such as EXT2, NTFS, Reiser)
EXT3
8. Physical Memory Available?
4GB
9. Are you using Replication (HA) with Berkeley DB XML? If so, please
describe the network you are using, and the number of Replica’s.
No
10. Are you using a Remote Filesystem (NFS) ? If so, for which
Berkeley DB XML/DB files?
No
11. What type of mutexes do you have configured? Did you specify
–with-mutex=? Specify what you find inn your config.log, search
for db_cv_mutex?
None. Did not specify -with-mutex during bdb compilation
12. Which API are you using (C++, Java, Perl, PHP, Python, other) ?
Which compiler and version?
Java 1.5
13. If you are using an Application Server or Web Server, please
provide the name and version?
Oracle Appication Server 10.1.3.4.0
14. Please provide your exact Environment Configuration Flags (include
anything specified in you DB_CONFIG file)
Default.
15. Please provide your Container Configuration Flags?
final EnvironmentConfig envConf = new EnvironmentConfig();
envConf.setAllowCreate(true); // If the environment does not
// exist, create it.
envConf.setInitializeCache(true); // Turn on the shared memory
// region.
envConf.setInitializeLocking(true); // Turn on the locking subsystem.
envConf.setInitializeLogging(true); // Turn on the logging subsystem.
envConf.setTransactional(true); // Turn on the transactional
// subsystem.
envConf.setLockDetectMode(LockDetectMode.MINWRITE);
envConf.setThreaded(true);
envConf.setErrorStream(System.err);
envConf.setCacheSize(1024*1024*64);
envConf.setMaxLockers(2000);
envConf.setMaxLocks(2000);
envConf.setMaxLockObjects(2000);
envConf.setTxnMaxActive(200);
envConf.setTxnWriteNoSync(true);
envConf.setMaxMutexes(40000);
16. How many XML Containers do you have? For each one please specify:
One.
1. The Container Configuration Flags
XmlContainerConfig xmlContainerConfig = new XmlContainerConfig();
xmlContainerConfig.setTransactional(true);
xmlContainerConfig.setIndexNodes(true);
xmlContainerConfig.setReadUncommitted(true);
2. How many documents?
Everytime the user logs in, the current xml document is loaded from
a oracle database table and put it in the Berkeley XML DB.
The documents get deleted from XML DB when the Oracle application
server container is stopped.
The number of documents should start with zero initially and it
will grow with every login.
3. What type (node or wholedoc)?
Node
4. Please indicate the minimum, maximum and average size of
documents?
The minimum is about 2MB and the maximum could 20MB. The average
mostly about 5MB.
5. Are you using document data? If so please describe how?
We are using document data only to save changes made
to the application data in a web application. The final save goes
to the relational database. Berkeley XML DB is just used to store
temporary data since going to the relational database for each change
will cause severe performance issues.
17. Please describe the shape of one of your typical documents? Please
do this by sending us a skeleton XML document.
Due to the sensitive nature of the data, I can provide XML schema instead.
18. What is the rate of document insertion/update required or
expected? Are you doing partial node updates (via XmlModify) or
replacing the document?
The document is inserted during user login. Any change made to the application
data grid or other data components gets saved in Berkeley DB. We also have
an automatic save every two minutes. The final save from the application
gets saved in a relational database.
19. What is the query rate required/expected?
Users will not be entering data rapidly. There will be lot of think time
before the users enter/modify data in the web application. This is a pilot
project but when we go live with this application, we will expect 25 users
at the same time.
20. XQuery -- supply some sample queries
1. Please provide the Query Plan
2. Are you using DBXML_INDEX_NODES?
Yes.
3. Display the indices you have defined for the specific query.
XmlIndexSpecification spec = container.getIndexSpecification();
// ids
spec.addIndex("", "id", XmlIndexSpecification.PATH_NODE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
spec.addIndex("", "idref", XmlIndexSpecification.PATH_NODE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
// index to cover AttributeValue/Description
spec.addIndex("", "Description", XmlIndexSpecification.PATH_EDGE | XmlIndexSpecification.NODE_ELEMENT | XmlIndexSpecification.KEY_SUBSTRING, XmlValue.STRING);
// cover AttributeValue/@value
spec.addIndex("", "value", XmlIndexSpecification.PATH_EDGE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
// item attribute values
spec.addIndex("", "type", XmlIndexSpecification.PATH_EDGE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
// default index
spec.addDefaultIndex(XmlIndexSpecification.PATH_NODE | XmlIndexSpecification.NODE_ELEMENT | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
spec.addDefaultIndex(XmlIndexSpecification.PATH_NODE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
// save the spec to the container
XmlUpdateContext uc = xmlManager.createUpdateContext();
container.setIndexSpecification(spec, uc);
4. If this is a large query, please consider sending a smaller
query (and query plan) that demonstrates the problem.
21. Are you running with Transactions? If so please provide any
transactions flags you specify with any API calls.
Yes. READ_UNCOMMITED in some and READ_COMMITTED in other transactions.
22. If your application is transactional, are your log files stored on
the same disk as your containers/databases?
Yes.
23. Do you use AUTO_COMMIT?
No.
24. Please list any non-transactional operations performed?
No.
25. How many threads of control are running? How many threads in read
only mode? How many threads are updating?
We use Berkeley XML DB within the context of a struts web application.
Each user logged into the web application will be running a bdb transactoin
within the context of a struts action thread.
26. Please include a paragraph describing the performance measurements
you have made. Please specifically list any Berkeley DB operations
where the performance is currently insufficient.
We are clocking 10-12 seconds of loading a document from dbd when
five users are on the system.
getContainer().getDocument(documentName);
27. What performance level do you hope to achieve?
We would like to get less than 5 seconds when 25 users are on the system.
28. Please send us the output of the following db_stat utility commands
after your application has been running under "normal" load for some
period of time:
% db_stat -h database environment -c
% db_stat -h database environment -l
% db_stat -h database environment -m
% db_stat -h database environment -r
% db_stat -h database environment -t
(These commands require the db_stat utility access a shared database
environment. If your application has a private environment, please
remove the DB_PRIVATE flag used when the environment is created, so
you can obtain these measurements. If removing the DB_PRIVATE flag
is not possible, let us know and we can discuss alternatives with
you.)
If your application has periods of "good" and "bad" performance,
please run the above list of commands several times, during both
good and bad periods, and additionally specify the -Z flags (so
the output of each command isn't cumulative).
When possible, please run basic system performance reporting tools
during the time you are measuring the application's performance.
For example, on UNIX systems, the vmstat and iostat utilities are
good choices.
Will give this information soon.
29. Are there any other significant applications running on this
system? Are you using Berkeley DB outside of Berkeley DB XML?
Please describe the application?
No to the first two questions.
The web application is an online review of test questions. The users
login and then review the items one by one. The relational database
holds the data in xml. During application load, the application
retrieves the xml and then saves it to bdb. While the user
is making changes to the data in the application, it writes those
changes to bdb. Finally when the user hits the SAVE button, the data
gets saved to the relational database. We also have an automatic save
every two minues, which saves bdb xml data and saves it to relational
database.
Thanks,
Madhav
[email protected]Could it be that you simply do not have set up indexes to support your query? If so, you could do some basic testing using the dbxml shell:
milu@colinux:~/xpg > dbxml -h ~/dbenv
Joined existing environment
dbxml> setverbose 7 2
dbxml> open tv.dbxml
dbxml> listIndexes
dbxml> query { collection()[//@date-tip]/*[@chID = ('ard','zdf')] (: example :) }
dbxml> queryplan { collection()[//@date-tip]/*[@chID = ('ard','zdf')] (: example :) }Verbosity will make the engine display some (rather cryptic) information on index usage. I can't remember where the output is explained; my feeling is that "V(...)" means the index is being used (which is good), but that observation may not be accurate. Note that some details in the setVerbose command could differ, as I'm using 2.4.16 while you're using 2.4.13.
Also, take a look at the query plan. You can post it here and some people will be able to diagnose it.

Need help with my usecase based on transient ViewObject
I am using 11.1.1.4.0 Jdev version. I need help with my usecase.Been trying it for 2 days but couldn't figure out the issue.
I have a transientVO . In this VO Rows will be populated programmatically. CountryId is an attribute of this VO. I have created a viewAccessor "CountriesVA" from Country VO of HR schema.
I have a LOV for the countryId which is based on this VA ,getting countries from CountryTable.
This is the model part which works fine.
Before the page load i have called a method to create a row for this transientVO.Once the row is created i can see the SOC in my page which i have created as below.
Now i want to insert a row in the transientVO if user selects a country and restrict duplicate entry . (As One row is already created 1st time there will be no rows created.after that rows will be inserted)
The issue is :: Suppose there are 2 countries. A & B .When user does the following actions :
Insert A . Done //as 1st entry
Insert B . Done //as 1st time entry
Insert A . duplicate not inserted
Insert B . getting inserted // the bug.

9.7.6 What You May Need to Know About Programmatic Row Set Iteration
The problem is solved ,the above links helped me solve the problem.
what i did is i have created a method in appmodule to iterate rows and all the method y operation bindings and my logic works fine ....
MY Advice to all Adf developers ,though i am not an expert but i can assure you to follow the above process for rowIteration.If you use the iterator binding in the manage bean to navigate the rows u'll face issues which are unexpected.
In AppModule :::::
public boolean createRow(String oldValue,String newValue){
System.err.println(oldValue+""+newValue);
ViewObjectImpl vo=getViewObj1();
boolean duplicate=false;
if(oldValue!=null){
RowSetIterator iter = vo.createRowSetIterator(null);
System.err.println("iterating rows ");
while (iter.hasNext()) {
Row r = iter.next();
System.err.println(iter.getRangeIndexOf(r)+" row is "+r.getAttribute("CountryId"));
if(r.getAttribute("CountryId").toString().equals(newValue)){
duplicate=true;
break;
// Do something with the current row.
// close secondary row set iterator
iter.closeRowSetIterator();
return duplicate;
In ManageBean :::::
public void countryIdVC(ValueChangeEvent valueChangeEvent) {
// Add event code here...
String oldValue=null;
System.err.println("Old Value"+valueChangeEvent.getOldValue());
setEL("#{bindings.CountryId.inputValue}", valueChangeEvent.getOldValue());
if(evaluateEL("#{bindings.CountryId.attributeValue}")!=null)
oldValue =evaluateEL("#{bindings.CountryId.attributeValue}").toString();
setEL("#{bindings.CountryId.inputValue}", valueChangeEvent.getNewValue());
String newValue=evaluateEL("#{bindings.CountryId.attributeValue}").toString();
BindingContainer bindings = BindingContext.getCurrent().getCurrentBindingsEntry();
//access the name of the iterator the table is bound to. Its "allDepartmentsIterator"
//in this sample
DCIteratorBinding dciter = (DCIteratorBinding) bindings.get("ViewObj1Iterator");
//access the underlying RowSetIterator
RowSetIterator rsi = dciter.getRowSetIterator();
if(oldValue!=null){
rsi.getCurrentRow().setAttribute("CountryId", oldValue);
OperationBinding operation = bindings.getOperationBinding("createRow");
operation.getParamsMap().put("oldValue", oldValue);
operation.getParamsMap().put("newValue", newValue);
if(!(Boolean)operation.execute()){
//get handle to the last row
Row lastRow = rsi.last();
//obtain the index of the last row
int lastRowIndex = rsi.getRangeIndexOf(lastRow);
//create a new row
Row newRow = rsi.createRow();
newRow.setAttribute("CountryId", newValue);
//initialize the row
newRow.setNewRowState(Row.STATUS_INITIALIZED);
//add row to last index + 1 so it becomes last in the range set
System.err.println("Inserting row at index "+lastRowIndex+1);
rsi.insertRowAtRangeIndex(lastRowIndex +1, newRow);
//make row the current row so it is displayed correctly
rsi.setCurrentRow(newRow);
else{
System.err.println("Data found So not inserting,only setting current Row");
Key key =new Key(new Object[] { newValue});
rsi.setCurrentRow(rsi.getRow(key)); -
i need help with my imessage i am using a Iphone 4 ios 6.1.3 but when i go to settings>message>send and reecieve. i only get the options Apple ID: and You can be reached by iMessage at: my current email and add another email. my question is how do i get it to where imessage uses my cell phone number instead of my Email i have looked all over the web and no luck......
The hidden text should be sent for you automatically by the phone. From personal experience, this is automatic, but something has obviously tripped up somewhere on your phone.
It appears from reading the documentation, I would first try signing out of your Apple ID by going to Settings > Messages > Send and Receive then press your Apple ID, and press Sign Out. Then sign back in. This should hopefully trigger a re-activation of your mobile number. Your mobile number should be assigned to your Apple ID on first sign-in so hopefully this signing in and out should trigger an automatic re-activation.
Failing that, others have posted a reset of the phone, as does the support page I quoted. It appears this could be a last resort as a reset can be a bit of a pain (although if you Back your phone up via iTunes, you should be able to restore it to how it is currently). I would try the signing in and out method. Hopefully, fingers crossed, it should kick your phone back into action. -
Need Help with a Flash Web Project
Hello, everyone. I am trying to use Flash to make a two-step
system. I want the flash document to, first, allow a person to
upload multiple image files and then, second, for the flash
document be able to create a slideshow with the uploaded images and
fade in and out from each image until the slideshow is over. I want
it to be where the flash document creates its own slideshow with
the images that are uploaded in the first step that I mentioned. I
want it to do it completely on its own so I need to know how to
give it the proper AI so that it can do this task.
So, are there any tips that anyone has on how to do this? Can
anyone tell me exactly how to do this? I really need help with this
for my new website project. Thanks in advance, everyone!The problem with the text not appearing at all has to do with you setting the alpha of the movieclip to 0%. Not within the movieclip, but the movieclip itself. The same for the xray graphic, except you have that as a graphic symbol rather than a movieclip. To have that play while inhabiting one frame you'll need to change it to a movieclip symbol.
To get the text to play after the blinds (just a minor critique, I'd speed up the blinds), you will want to add some code in the frame where you added the stop in the blinds animation. You will also need to assign instance names for the text movieclips in the properties panel, as well as place a stop(); in their first frames (inside).
Let's say you name them upperText and lowerText. Then the code you'd add at the end of the blinds animation (in the stop frame) would be...
_parent.upperText.play();
_parent.lowerText.play();
The "_parent" portion of that is used to target the timeline that is containing the item making the command, basically meaning it's the guy inside the blinds telling the guy outside the blinds to do something.
You'll probably want to add stops to the ends of the text animations as well.
If you want to have the first text trigger the second text, then you'd take that second line above and place it in the last frame of the first text animation instead of the blinds animation.
Note, on occasion, undeterminably, that code above doesn't work for some odd reason... the animation plays to the next frame and stops... so if you run into that, just put a play(); in the second frame to help push it along.
PS GotoandPlay would actually be gotoAndPlay, and for the code above you could substitute play(); with gotoAndPlay(2); -
Need help with the session state value items.
I need help with the session state value items.
Trigger is created (on After delete, insert action) on table A.
When insert in table B at least one row, then trigger update value to 'Y'
in table A.
When delete all rows from a table B,, then trigger update value to 'N'
in table A.
In detail report changes are visible, but the trigger replacement value is not set in session value.
How can I implement this?You'll have to create a process which runs after your database update process that does a query and loads the result into your page item.
For example
SELECT YN_COLUMN
FROM My_TABLE
INTO My_Page_Item
WHERE Key_value = My_Page_Item_Holding_Key_ValueThe DML process will only return key values after updating, such as an ID primary key updated by a sequence in a trigger.
If the value is showing in a report, make sure the report refreshes on reload of the page.

Hi, I'm not sure if I'm allowed to post questions on this forum but I can't find anywhere to talk to helpful people about programming.
I'm making a dnd interface for JComponents. So far I've made a simple program that has a Component that can be lifted from a container and braught to the glass pane then later moved to anywhere on the screen and dropped into the container below it. Here's where my problems come:
1) Rite now my 'Movable Component' is a JPanel which is just colored in. I want to either take a Graphic2d from a JComponent/Component and draw it on the JPanel or change the JPanel to the component I want to paint and disable the component.
The problem with getting the Graphics2d is that if the component isn't on the screen it doesn't make a graphic object. I tried messing with the ui delicate and overriding parental methods for paintComponent, repaint, and that repaintChildren(forget name) but I haven't had luck getting a good graphics object. I was thinking of, at the beginning of running the program, putting 1 of each component onto the screen for a second then removing it but I'd rather not. I'd also like to change the graphics dynamicly if someone stretches the component there dropping and what not.
The problem with disabling is that it changes some of the visual features of Components. I want to be able to update the Component myself to change how it looks and I don't want disabling to gray out components.
I mainly just dont want the components to do any of there normal fuctions. This is for a page builder, by the way.
Another problem I'm having is that mouseMotionListener is allowing me to select 2 components that are on top of one another when there edges are near each other. I don't know if theres a fix to this other than changing the Java Class.
My next problem is a drop layout manager, but I'm doing pretty good with that rite now. It'll problem just move components out of the way of the falling component.
One last thing I need help with is that I don't want the object that's being carried to go across the menu bar and certain areas. When I'm having the object being carried I have it braught up to the glass pane which allows it to move anywhere. Does anyone have any idea how I could prevent the component from being over the menu bars and other objects? I might have to make 1 panel is the movable area that can then be broken down into the 'component bank', 'building page' and whatever else I'm gonna need.
This is all just test code to get together for when I make the real program but I need to make sure it'll be possible without a lot of hacking of code.
Sorry for the length. Thanks for any help you can give.The trick to making viewable components that have no behaviour, is to render them onto an image of some sort (eg a BufferedImage). You can then display the Image on a JLabel that can be dragged around the desktop.
Here is a piece of code that does the component rendering for you. This particular example uses a fixed component size, but you can modify that as you choose of course...public class JComponentImage
private static GraphicsConfiguration gConfig;
private static Dimension compSize = new Dimension(80, 22);
private static Image image = null;
public static Image getImage(Class objectClass)
if (gConfig == null)
GraphicsEnvironment gEnv = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice gDevice = gEnv.getDefaultScreenDevice();
gConfig = gDevice.getDefaultConfiguration();
image = gConfig.createCompatibleImage(compSize.width, compSize.height);
JComponent jc = (JComponent) ObjectFactory.instantiate(objectClass);
jc.setSize(compSize);
Graphics g = image.getGraphics();
g.setColor(Color.LIGHT_GRAY);
g.fillRect(0, 0, compSize.width, compSize.height);
g.setColor(Color.BLACK);
jc.paint(g);
return image;
}And here is the class that makes the dragable JLabel using the class above...public class Dragable extends JLabel
private static DragSource dragSource = DragSource.getDefaultDragSource();
private static DragGestureListener dgl = new DragMoveGestureListener();
private static TransferHandler th = new ObjectTransferHandler();
private Class compClass;
private Image image;
Dragable(Class compClass)
this.compClass = compClass;
image = JComponentImage.getImage(compClass);
setIcon(new ImageIcon(image));
setTransferHandler(th);
dragSource.createDefaultDragGestureRecognizer(this,
DnDConstants.ACTION_COPY,
dgl);
public Class getCompClass()
return compClass;
}Oh and here is ObjectFactory which simply instantiates Objects of a given class and sets their text to their classname (very crudely)...public class ObjectFactory
public static Object instantiate(Class objectClass)
Object o = null;
try
o = objectClass.newInstance();
catch (Exception e)
System.out.println("ObjectFactory#instantiate: " + e);
String name = objectClass.getName();
int lastDot = name.lastIndexOf('.');
name = name.substring(lastDot + 1);
if (o instanceof JLabel)
((JLabel)o).setText(name);
if (o instanceof JButton)
((JButton)o).setText(name);
if (o instanceof JTextComponent)
((JTextComponent)o).setText(name);
return o;
}Two more classes required by this codepublic class ObjectTransferHandler extends TransferHandler {
private static DataFlavor df;
* Constructor for ObjectTransferHandler.
public ObjectTransferHandler() {
super();
try {
df = new DataFlavor(DataFlavor.javaJVMLocalObjectMimeType);
} catch (ClassNotFoundException e) {
Debug.trace(e.toString());
public Transferable createTransferable(JComponent jC) {
Transferable t = null;
try {
t = new ObjectTransferable(((Dragable) jC).getCompClass());
} catch (Exception e) {
Debug.trace(e.toString());
return t;
public int getSourceActions(JComponent c) {
return DnDConstants.ACTION_MOVE;
public boolean canImport(JComponent comp, DataFlavor[] flavors) {
if (!(comp instanceof Dragable) && flavors[0].equals(df))
return true;
return false;
public boolean importData(JComponent comp, Transferable t) {
JComponent c = null;
try {
c = (JComponent) t.getTransferData(df);
} catch (Exception e) {
Debug.trace(e.toString());
comp.add(c);
comp.validate();
return true;
public class ObjectTransferable implements Transferable {
private static DataFlavor df = null;
private Class objectClass;
ObjectTransferable(Class objectClass) {
try {
df = new DataFlavor(DataFlavor.javaJVMLocalObjectMimeType);
} catch (ClassNotFoundException e) {
System.out.println("ObjectTransferable: " + e);
this.objectClass = objectClass;
* @see java.awt.datatransfer.Transferable#getTransferDataFlavors()
public DataFlavor[] getTransferDataFlavors() {
return new DataFlavor[] { df };
* @see java.awt.datatransfer.Transferable#isDataFlavorSupported(DataFlavor)
public boolean isDataFlavorSupported(DataFlavor testDF) {
return testDF.equals(df);
* @see java.awt.datatransfer.Transferable#getTransferData(DataFlavor)
public Object getTransferData(DataFlavor arg0)
throws UnsupportedFlavorException, IOException {
return ObjectFactory.instantiate(objectClass);
}And of course the test class:public class DragAndDropTest extends JFrame
JPanel leftPanel = new JPanel();
JPanel rightPanel = new JPanel();
Container contentPane = getContentPane();
Dragable dragableJLabel;
Dragable dragableJButton;
Dragable dragableJTextField;
Dragable dragableJTextArea;
* Constructor DragAndDropTest.
* @param title
public DragAndDropTest(String title)
super(title);
dragableJLabel = new Dragable(JLabel.class);
dragableJButton = new Dragable(JButton.class);
dragableJTextField = new Dragable(JTextField.class);
dragableJTextArea = new Dragable(JTextArea.class);
leftPanel.setBorder(new EtchedBorder());
BoxLayout boxLay = new BoxLayout(leftPanel, BoxLayout.Y_AXIS);
leftPanel.setLayout(boxLay);
leftPanel.add(dragableJLabel);
leftPanel.add(dragableJButton);
leftPanel.add(dragableJTextField);
leftPanel.add(dragableJTextArea);
rightPanel.setPreferredSize(new Dimension(500,500));
rightPanel.setBorder(new EtchedBorder());
rightPanel.setTransferHandler(new ObjectTransferHandler());
contentPane.setLayout(new BorderLayout());
contentPane.add(leftPanel, "West");
contentPane.add(rightPanel, "Center");
public static void main(String[] args)
JFrame frame = new DragAndDropTest("Drag and Drop Test");
frame.pack();
frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
frame.setVisible(true);
}I wrote this code some time ago, so it won't be perfect but hopefully will give you some good ideas.

NEED HELP WITH WORKFLOW CONFIGURATION
I need help with 3 situations below. Please help me with these. How do I configure these. I also haveto provide specs to the Abaper. What exactly do I need to include in the specs. I anyone has the specs similar to these please send me over. Also tell me what I need to do to get these requirements fulfilled.
1) Description:
This is a workflow requirement to serve as a reminder of upcoming investment
maturities.
Requirements Details:
Create a workflow to serve as a reminder of upcoming investment maturities.
Donor System Processing Narrative:
Read the maturity dates on investments.
Target System Processing Narrative:
Send a notice to the parties that an investment will be maturing soon.
2) Description:
Implement workflow to route invoice receipts using a one time vendor for management
review and posting
Desired Functionality:
If a one time vendor is entered by the AP Voucher Clerk the invoice will be automatically
parked by the program and a workflow notification triggered to the Accounting
Supervisor and Accounting Manager (backup). The Accounting Supervisor will review
the parked document and imaged copy of the actual invoice and post the parked
document.
3) Description:
An approval workflow is needed for credit memos posted to SAP customer accounts.
Desired Functionality:
The Cash Journal Clerk will post a credit memo to the customer account using transaction
FV75 Park Customer Invoice. This transaction will automatically trigger a workflow to
the Accounting Manager for approval and then to the CFO who will approve and post the
parked document. (In order for this transaction to automatically trigger what configuration needs to be done).Bob;
You can borrow the example code that ships with both NI-DAQ (in case you are doing NI-DAQ function calls) and Labview. The best examples to start with are the ones that have the prefix STC.
Hope this helps.

Need help with a currently "in-use" form we want to switch to Adobes hosting service
Hi, I am in desperate need of help with some issues concerning several forms which we currently use a paid third party (not Adobe) to host and "re-distribute through email"...Somehow I got charged $14.95 for YOUR service, (signed up for a trial, but never used it)..and now I am paying for a year of use of the similar service which Adobe is in control of. I might want to port my form distribution through Adobe in the hopes of reducing the errors, problems and hassles my customers are experiencing when some of them push our "submit button". (and I guess I am familiar with these somewhat from reading what IS available in here, and I also know that, Adobe is working to alleviate some of these " submit" issues, so let's don't start by going backwards, here) I need solutions now for my issues or I can leave it as is, If Adobe's solution will be no better for my end users...
We used FormsCentral to code these forms and it works for the most part (if the end-user can co-operate, and thats iffy, sometimes), but I need help with how to make it go through your servers (and not the third party folks we use now), Not being cruel or racist here, but your over the phone "support techs" are about horrible & I cannot understand them or work with any of them, so I would definitely need someone who speaks English and can understand the nuances of programming these forms, to please contact me back. (Sorry, but both those attributes will be required to be able to help me, so, no "newbie-interns" or first week trainees are gonna cut it).... If you have anyone who fits the bill on those items and would be willing to help us, please contact me back at your earliest convenience. If we have to communicate here, I will do that & I can submit whatever we need to & to whoever we need to.
I need to get this right and working for the majority of my users and on any platform and OS.
You may certainly call me to talk about this, and I have given my number numerous times to your (expletive deleted) time wasting - recording message thingy. So, If it's not available look it up under [email protected]
(and you will probably get right to me, unlike my and I'm sure most other folks', "Adobe phone-in experiences")
Thank You,

Phenix City, Alabama 36869Well, thanks for writing back...just so you know...I started using Adobe products in 1987, ...yeah...back then...like Illustrator 1 & 9" B&W Macs ...John Warnock's Helvetica's....stuff like that...8.5 x 11 LaserWriters...all that good stuff...I still have some of it working on a mac...much of it was stuff I bought. some stuff I did not...I'm not a big fan of this "cloud" thing Adobe has foisted upon the creatives of the world...which I'm sure you can tell...but the functionality and usefulness of your software can not be disputed, so feel free to do whatever we will continue to pay for, ...I am very impressed with CC PS on the 64 bit PC and perhaps I will end up paying you the stipend that you demand for the other services.
So I guess that brings us to our problem.. a few years back and at the height of the recession and near bankruptcy myself, I was damn lucky and hit on something and began a small arts and crafts supply service to sell my products online to a very "niche market" ...I had a unique product and still sell that product (plus others) online...My website is www.vinylcouture.com...Strange? Yes...but there is a market it seems, for everything now, and this is the market I service...Catagorically, these are 99%+ women that use these "adhesive, sticky backed vinyl products" to make different "craft items" that are just way too various and numerous to go into... generally older women, women who are computer illiterate for the most part...and all this is irrelevant to my problem, but I want you to have every bit of background on this and especially the demographic we are dealing with, so we can get right to the meat of the problem.
OK...So about two years ago, I decided to offer a "plain sheet" product of a plain colored "stick back" vinyl... it is available in multiple quantities of packs ( like 5 pieces, 10 pieces, 15 pieces, in a packi & so on)...and if you are still on my site.. go to any "GO RIGHT TO OUR ORDER PAGE" button, scroll down a little...and then to the "PLAIN VINYL" section...you will see the Weebly website order process.) You can back out from here, I think,..but, anyway this product is available in 63 colors + or - a few. So then the problem is, how do they select their individual colors within that (whatever) pack?... .
So my initial idea was to enable a "selection form" for these "colors" that would be transmitted to me via email as 'part" of the "order process".. We tried getting our customers to submit a " a list" ( something my competitiors still do, lol, poor bastards)......but that..is just unbelievable..I can't even begin to tell you what a freakin' nightmare that was...these people cannot even count to 10, much less any higher... figuring out what colors to list and send me... well, lets just say, it wasn't working......I had to figure out a better way...Something had to be done.
So after thinking this all out, and yeah...due to my total ignorance, i figured that we could make a form with Live Cycle Designer (Now Forms Central)...(back then something that was bundled with Adobe Acrobat Pro), I believe, and thats what this thing was authored in... and it would be all good...LOL!
Well not so simple...as you well know, Adobe Acrobat would NOT LET YOU EMAIL anything from itself.....it just wouldn't work (and I know why, and all that hooey), but not being one to take NO for answer,.I started looking for a way to make my little gizmo work.. So I found this company that said they can "hijack" (re-direct actually) the request to email, bypass the wah-wah, and re-transmit it to the proper parties.....for less than $100 a year, I think...its called http://pdf-fillableforms.com/.
A nice gentleman named Joseph Silva helped us program the thing to go to his servers and back out. Please dont hassle them...I need them...for now..it basically does work...try it...you should get back a copy of the form that you filled out...good luck however, if you're on MAC OSX or similar...
I have included a copy of both of our forms (and feel free to fill it out and play with it)...just put test somewhere on it...(and you must include YOUR email or it will balk)..they are supposed to be mostly identical, except one seems to be twice as large....generating a 1.7 meg file upon submission, while the other one only generates a 600K file or so...thats another issue for another day or maybe you can advise on that also...
OK so far so good......In our shop, once Grandma buys a 10 pack (or whatever), Only then she gets to the link on her receipt page ro the relevant "selection form" ,(this prevents "Filling and Sending" with "no order" and "no payment", another early problem we had)... which they can click on and it will usually download and open up on their device if all goes well...Then our little form is supposed to be fillable and is supposed to ADD UP all the quantities, so grandma knows how many she is buying and so forth right on the fly, and even while she changes her mind..., and IT'S LARGE so grandma can see it, and then it TOTALS it all up for them, ( cause remember, they can NOT add).., except there is a programming bug (mouse-click should be a mouse-up probably or something..) which makes you click in the blank spaces to get to a correct TOTAL...about 70-80% of our customers can enable all these features and usually the process completes without problems for them especially on PC's running Windows OS and Acrobat Reader X or XI...at least for most... Unfortunately it is still not the "seamless process" I would like or had envisioned for the other folks out there that do have trouble using our form.... Many folks report to us the following issues that we know of. First of all it takes too much time to load up...We know its HUGE...is there anyway that you can see, to streamline this thing? I would love for it to be more compact...this really helps on the phones and pads as I'm sure you well know.
Some just tell us,"it WON'T work"....I believe this is because they are totally out of it and dont even have Adobe Reader on their machine, & don't know how to get it ( yes, we provide the links).....or it's some ancient version....no one can stop this one...
It almost always generates some kind ( at least one time) of "error message" which we do warn them about..., telling one, basically that "Acrobat doesnt even like this happening at all, and it could be detrimental to ones computer files", blah-blah...(this freaks grandma out really bad)...& usually they end up not even trying to send it... and then I get calls that even you wouldn't believe...& If they DO nut up and push the Red "Submit Form" button, it will usually send the thing to us (and also back to them at the "required email address" they furnished on the form, thats what the folks at the "fillable forms place" do) so, if it's performing it's functions, why it is having to complain?. What are we doing wrong?....and how can I fix it?...Will re-compiling it or saving it as a newer version of "FormsCentral" correct any of these problems ?
Ok, so that should keep you busy for a minute and we can start out with those problems...but the next thing is, how can I take advantage of YOUR re-direct & hosting services?, And will it get rid of the error messages, and the slowness, and the iOS incompatibilities ? (amazingly, the last iOS Reader version worked almost OK.. but the newest version doesnt seem to work with my form on my iphone4) If it will enable any version of the iOS to send my form correctly and more transparently, then it might be worth the money...$14.95 a MONTH you say. hmmmmm...Better be good.
Another problem is, that I really don't need 5000 forms a month submitted. I think its like 70-100 or less....Got any plans for that? Maybe I'm just not BIG ENOUGH to use Adobe's services, however in this case, I really don't care whose I do use as long as the product works most correctly for my customers as well as us. Like I said, If I'm doing the best I can, I won't change anything, and still use the other third party, If Adobe has a better solution, then i'm all for that as well. In the meantime, Thanks for any help you can provide on this...
