How do I omit an object when serializing?
I want to serialize a class that has an object of a class that has an AudioClip object in it and Java is not letting me serialize it. I think there is a way to tell the output stream to skip an object in a class but I can't remember how and I can't find much help online. Can someone help me?
for anything you want to have serialized declare its class implements Serializable
for anything field you want to skip on serialization declare the field transient

How to replace all existed objects when impdp a schame ???
I wrote 2 functions which do expdp and impdp
the impdp funciton is :
create or replace function impdp_schema(fromusr in varchar2,
tousr in varchar2,
dir in varchar2,
dmpfile in varchar2,
logfile in varchar2 default null)
return number as
h1 NUMBER;
job_name varchar2(128);
job_state varchar2(32767);
ret number;
BEGIN
if dir is null or dmpfile is null then
return 1;
end if;
ret := 0;
job_name := 'IMP' || to_char(sysdate, 'yyyymmddhh24miss');
h1 := DBMS_DATAPUMP.OPEN('IMPORT',
'SCHEMA',
NULL,
job_name,

DBMS_DATAPUMP.KU$_COMPRESS_METADATA);
DBMS_DATAPUMP.ADD_FILE(h1,

How can I animate an object when it is clicked on like a hyperlink?
I'm creating a game for teaching purposes. Imagine Family Feud. Six boxes on a slide. Under each box is an answer. Clicking on any box makes it go away and reveals the answer. Since it is impossible to know the order of the selections, I can't hyperlink to a new slide. Animations only seem to be triggered by "mouse click" or "with previous" which does not allow individual selection and random order. Powerpoint for Windows had a "triggers" feature which allowed objects to animate individually when selected. Is there something in Keynote that would do this?
Welcome to the forums!
Keynote is not designed to do non-linear multimedia -- it is just a presentation application, intended for linear slide-by-slide shows. Unfortunately it does not have a feature similar to PowerPoint's triggers. -
I'm using Flash CS3, running code in ActionScript 3.
I use the Loader class to load a child SWF file, which then
takes over the entire area on my website that is reserved for
Flash. If the user decides to stop watching the SWF file before it
is completed, he hits the "close" button within the child SWF,
ultimately causing the Loader.unload() method to be executed. So
far, so good, only the sound from the remaining portion of the SWF
file keeps playing. According to the Flash Docs for the
Loader.unload() method:
"As a best practice, before you unload a child SWF file, you
should explicitly close any streams in the child SWF file's
objects, such as LocalConnection, NetConnection, NetStream, and
Sound objects. Otherwise, audio in the child SWF file might
continue to play, even though the child SWF file was unloaded."
It then gives an example that assumes you already have access
to the Sound object, so closing the Sound object is done by:
mySound.close();
The only problem is that I have no idea how to access the
Sound object when I use the Loader.load() method. Where is this
beast? I can't seem to find anything in the documentation that
tells me how to find the Sound object after calling Loader.load().
As a temporary fix, I modified the target SWF file so that when the
"close" button is hit, it calls the "stop()" function; however,
this only stops the sound, it does not close the associated Sound
object, and I presume it continues to lurk around in memory with
nothing useful to do. (When the user hits the "close" button in the
child SWF file, it creates a "bubbling" event so that the Loader
class can call the Loader.unload() method on it.)
I've attached code for your reference.
Any help is deeply appreciated!
-DanAck! Looks like I hijacked this thread, sorry.
I'm doing almost exactly the same thing the OP is doing...
Loader class to load an external SWF (which is a video file FLV).
If the user hits the "close" button on the video, the video goes
away as it should but the audio continues.
I understand that I need to close any NetConnection and
NetStream objects in addition to unloading the movie. What I don't
understand is how to do that. I'm sure that it's a syntax thing I'm
just not getting right. I would just really like a more detailed
explanation of stopping NetConnections and NetStreams (but an
explanation for the not-so-actionscript-experienced LOL).
Thanks. -
Script Object when rendering to HTML
Hi,
I am developing a form that requires the same script to be reused many times. This form is going to be rendered out to HTML through Workflow, and I'm not sure how to access a script object when rendering to HTML. The root of my form is MISForm so I tried this:
MISForm.variables.getXML.getXMLDoc("http://lcwftest:8080/services/getEmployeeInfo?method=s ynchronousInvoke&empnum="+this.rawValue);
getXML being the script object and getXMLDoc being the function. But this returns MisForm is not defined.
I also tried a reference straight to the object
getXML.getXMLDoc("http://lcwftest:8080/services/getEmployeeInfo?method=synchronousInvoke&e mpnum="+this.rawValue);
but that also returned "is not defined"
How do I reference the script object.I believe it gets something like
xfa.resolveNode("MISForm").getXML.getXMLDoc...
It also depends on if your script object is located in the root or if it is located within your page if you understand what I am trying to say. With pdf you can have a global script and reference it on each page but with html I would be more than happy if you find a solution on it... you have to have the script object on each page. -

How to remove duplicates when serializing?
hi,
I think this has been asked before but have not been able to find the answer in the forums or google..
I'd like to save space when serializing a structure to disk, as the storage medium is slow and it is expensive to deserialize large objects. I know that the thing I'm serializing has the same object duplicated in it several times and that its being written out several times.
is there any way to do this (3rd party libraries etc..)?
ideally you'd also be able to configure whether objects are duplicated or not by identity or .equals equality?
thanks,

If you want to avoid serializing "same by equals" you'll probably have to roll your own, overriding readObject/writeObject or whatever methods the docs say to override for custom serialization.
Be aware though, that "same by equals" doesn't really mean the objects will behave the same way. I'd be very careful using that. -

How to create lock object when the total length is more than 300bytes?
Dears:
I want to create lock object for a add-on table , and the total length of table's fields is more than 300 bytes.
When I acitve this object, it will show "Total length of lock argument for table ZTEST_XXX longer than 300" error message in log.
Is there any way which can create lock object when total length > 300bytes?
Thanks in advance.
Best regards
LilyHi, Sudhi Karkada Sandeep Kumar
Thank you very much for your help.
When the total length of keys is more than 150bytes, lock object can't be created.

How to avoid submitting a page when tabular form rows are empty
Hi,
I have a master detail form in my application. There are 2 tables that are used Table A and Table B. Table A contains Ticket number and Table B refers to Table A through a foriegn key and Table B have columns like Date,Name, Age, ticket_id (that refers to the ticket_number of the Table A).
This is how the application works:
In a page there is a field for Ticket Number, once the user enters the Ticket Number and click Add Details, a tabular Form with 5 empty field appears... (Done through Page Process->Data Manipilation->Add Rows)
This form contains fields Date, Name and Age. Once the user fills in all the details and click Submit button, the page is submitted. Whatever values that was entered is saved in Table B. Page Sucess message appears. This works fine.
But once the Ticket Number is entered and Add Details is clicked, and without entering the values in the Tabular Form, if Submit button is clicked, there is no error showing up neither I see Page success message. But this should not be allowed. There should be some error showing up...
Tabular Form Validations works only when user enters some values in the Tabular Form and click Submit. For the above scenario, where the form is untouched the validation doesnt work.
How can I get this done? Any ideas?Hello Suzi,
>> if (document.wwv_flow==null)
The document.wwv_flow is an object representing the current form that was just rendered on your screen. As such, it can never be null.
>> How to avoid submitting a page when tabular form rows are empty
The correct way, especially for versions prior to APEX 4.0 is to use JavaScript, but for that, you need to know and understand how APEX generates your tabular form, HTML wise.
To be very brief, APEX attached a unique ID to every updatable cell in the tabular form, using a certain pattern – each updatable column is getting a unique name (e.g. ‘f01’,’f02’ etc.) and the ID of a cell is a combination of this name with the serial row number the cell is on. For example, a cell on the third row in an updatable column called ‘f04’ will be given an ID of f04_0003. (More detailed explanation, with an example, can be found in my book).
What you should do is to check these cells according to your validation policy (e.g. is all five row must be filled, is all the columns in a specific row must be filled, etc.).

Arie.

How to Use Transient View Objects to Store Session-level Global Variables
hi
Please consider section "40.8.5 How to Use Transient View Objects to Store Session-level Global Variables"
at http://download.oracle.com/docs/cd/E14571_01/web.1111/b31974/bcstatemgmt.htm#ADFFD19610
Based on this documentation I created the example application
at http://www.consideringred.com/files/oracle/2010/ProgrammaticalViewObjectAndRollbackApp-v0.01.zip
It behaves as show in the screencast at http://screencast.com/t/qDvSQCgpvYdd
Its Application Module has a Transient View Object instance "MyEmployeesContextVOVI", as master for the child View Object instance "EmpInCtxJobVI".
On rollback the Transient View Object instance keeps its row and attribute values.
Also when passivation and activation is forced (using jbo.ampool.doampooling=false ) the Transient View Object instance seems to keep its row and attribute values.
questions:
- (q1) Why does the expression #{bindings.MyEmployeesContextVOVIIterator.dataControl.transactionDirty} evaluate as true when a Transient View Object instance attribute value is changed (as shown in screencast at http://screencast.com/t/qDvSQCgpvYdd )?
- (q2) What would be a robust approach to make a Transient View Object instance more self-contained, and manage itself to have only one single row (per instance) at all times (and as such removing the dependency on the Application Module prepareSession() as documented in "5. Create an empty row in the view object when a new user begins using the application module.")?
many thanks
Jan VerveckenThanks for your reply Frank.
q1) Does sample 90 help ? http://blogs.oracle.com/smuenchadf/examples/
Yes, the sample from Steve Muench does help, "90. Avoiding Dirtying the ADF Model Transaction When Transient Attributes are Set [10.1.3] "
at http://blogs.oracle.com/smuenchadf/examples/#90
It does point out a difference in marking transactions dirty by different layers of the framework, "... When any attribute's value is changed through an ADFM binding, the ADFM-layer transaction is marked as dirty. ...".
This can be illustrate with a small change in the example application
at http://www.consideringred.com/files/oracle/2010/ProgrammaticalViewObjectAndRollbackApp-v0.02.zip
It now shows the result of both these expressions on the page ...
#{bindings.MyEmployeesContextVOVIIterator.dataControl.transactionDirty}
#{bindings.MyEmployeesContextVOVIIterator.dataControl.dataProvider.transaction.dirty}... where one can be true and the other false respectively.
See also the screencast at http://screencast.com/t/k8vgNqdKgD
Similar to the sample from Steve Muench, another modification to the example application introduces MyCustomADFBCDataControl
at http://www.consideringred.com/files/oracle/2010/ProgrammaticalViewObjectAndRollbackApp-v0.03.zip
public class MyCustomADFBCDataControl
extends JUApplication
@Override
public void setTransactionModified()
ApplicationModule vApplicationModule = (ApplicationModule)getDataProvider();
Transaction vTransaction = vApplicationModule.getTransaction();
if (vTransaction.isDirty())
super.setTransactionModified();
}Resulting in what seems to be more consistent/expected transaction (dirty) information,
see also the screencast at http://screencast.com/t/756yCs1L1
Any feedback on why the ADF Model layer is so eager to mark a transaction dirty is always welcome.
Currently, question (q2) remains.

How can you move the objects from one server to another?
how can you move the objects from one server to another?
Hi,
Collecting objects for Transporting
1. rsa1->transport connection
2. left panel choose 'object type', middle panel choose 'infocube' and 'select objects'
3. then choose your infocube and 'transfer'
4. will go to right panel, choose collection mode 'manual' and grouping only 'necessary objects'
5. after objects collection finished, create request
6. If they are $TMP, then change the package.
7. When you click the Save on the change package, it will prompt for transport. Here you can provide an existing open transport request number, or if you like here itself you can create a new one.
8. You can check the request in SE09 to confirm.
Releasing Transport Request
Lets say you are transporting from BWD to BWQ
Step 1: In BWD go to TCode SE10
Step 2: Find the request and release it (Truck Icon or option can be found by right click on request #)
Note: First release the child request and then the parent request
Steps below are to import transport (generally done by basis )
Step 1: In BWQ go to Tcode STMS
Step 2: Click on Import queue button
Step 3: Double Click on the line which says BWQ (or the system into which transport has to be imported)
Step 4: Click on refresh button
Step 5: High light the trasnport request and import it (using the truck icon)

How can I create a object for a note?
Hi experts,
I need to apply the note 501905 but when I try in the SNOTE transacction I receive this error:
Object REPS Z_MRM_DELETE_PP does not exist; create it
Diagnosis
The SAP Note that you want to implement contains changes to an object that does not yet exist in your system.
SAP Notes contain only changes to objects that already exist. This means that the the system cannot automatically create new objects during the implementation of this SAP Note.
Procedure
1. Cancel the SAP Note implementationl.
2. Create an empty object REPS Z_MRM_DELETE_PP with the corresponding object editor.
3. Restart the SAP Note implementation.
How can I create that Object??
Thanks for the help!Hi Carlos,
It says that you have to create a new program with a name Z_MRM_DELETE_PP.
Once you create and activate the program you can execute the SAP Note.
All this processure will be written in the SAP Note.
Please Go through the Note using below:
Step1: Use T.code SNOTE.
Step2: Use menu GOTO --> NOTE BROWSER. Provide the Note no and EXECUTE.
Step3: Double click on the displayed line.
Here you will get the information to do before implementing the note.
Go through all the documentation, and once you did all the development given in the note then you can implement the note.
