How to load second level nodes dynamically in jTree?
Hi,
I'm new to jTree & I want to load jTree with two levels of Hierarchy dynamically.
First level nodes I loaded from the database directly.
And regarding the second level nodes, I want them to be loaded only when I expand the first level nodes(on tree expansion), instead of loading it before-hand itself.
I tried this in TreeExpansion event, but still my tree was not refreshed.
Is there anyother way to do this .....?
Thanks.
G.
Hi sangar;
use method valueChanged() in ListSelectionEvent interface to notify tree selection change.

How to Load a SWF in Dynamically Loaded HTML
Hello,
I have a Flash movie with a multi-line text field that loads
HTML text. As per the below Macromedia documentation I have swfs as
images inside my HTML text.
I'm trying to find a way to pre-load these swfs - if I do
loadmovie to load the swf, when the html file is loaded will it
need to reload the swf from scratch or will it take my loaded
version? I'd love to show a "loading" message in the text as the
swf was loading but am unsure how to do this now that I have the
swf reference embedded in the html text.
Any ideas?
Thanks!
Julia
From the Macromedia documentation:
Image tag (<img>
The <img> tag lets you embed external JPEG files, SWF
files, and movie clips inside text fields. The <img> tag has
one required attribute, src, which specifies the path to a JPEG
file, a SWF file, or the linkage identifier of a movie clip symbol.Thanks - your answer is exactly what I was looking for.
I'm noticing that every swf I load via dynamic HTML is
distorted - is there a way to prevent this? I can set the width and
height of each swf in the HTML, which works ok, but then I run into
a problem when I try and have a component item (like an accordion)
included in the dynamic text field. It works properly, and the
framing is sized correctly, but the guts are still skewed. I
haven't been able to figure out why the swfs are being distorted in
the first place.
Any ideas?
Thanks,

How to load doc-level JavaScript via FDF
I apologize if this question is answered elsewhere on the forum -- I've spent a fair amount of time searching through the forum and other resources brought up in response to Google searches, all without a solid result; therefore I'm hoping that someone in the forum can help out.
I've got several dozen PDF forms that all use the same core set of JavaScript functions to perform various validation and formatting processes. So far, I've loaded this library as a document-level script in each PDF and then loaded the PDFs to the server.
When a user requests to view their specific document, the link that they click actually generates an FDF file that is sent to their browser. The FDF causes the target PDF to be loaded in the browser, into which the FDF data is loaded. A page load Script executes the do_DocLoad function, which sets up the document for initial user use (populates combo boxes, etc.) The user then can interact with the form in various ways and then, optionally, submit the data back to the server for processing. The library functions are referenced in various field formatting or validation calls, as well as by the Submit button that I've got on the form that performs a final field validation prior to submission. So far, this process works very well.
The issue is that every time a change, even a minor one, is needed in any of the core set of library functions, we have to open each and every PDF to apply the change, then save it and upload the entire batch to the server. Because of the significant amount of time that this can take (which will increase as the PDF library grows), I'd like to instead load the JavaScript functions in the FDF.
The ideal would be a method to allow the FDF to cause Acrobat to load the script from a file on the server, similar to how the PDF is called. Because I don't know if that would even work, I'm looking at having the ASPX page that processes the FDF, merging the user's data into the FDF format before serving it to the browser also merge in the script and serve it all up piping hot for the user's enjoyment (or so we hope). I've tinkered with the FDF, adding a /JavaScript section at the end of the FDF as follows:
<< /V (~data_client_name~)/T (client_name)>>
<< /V (~data_client_address~)/T (client_address)>>]
/F (~data_FileName~)/ID [ < blah blah >< blah blah >]
/JavaScript << /Doc 2 0 R >>
>>
>>
endobj
2 0 obj [ (DocScript1) 3 0 R ] endobj
3 0 obj <<>>
stream
** script goes here **
endstream
endobj
trailer << /Root 1 0 R >>
%%EOF
In the section where ** script goes here ** I have attempted to paste the script library, without success. This library consists of several different JavaScript functions.
In testing, the above didn't work, unfortunately. :-( I got all kinds of wierd data in the form fields that are processed by the functions that I was trying to load - the page open calls didn't return any errors, which was good, but the fields formatted by the initial setup method were all messed up. I'm looking for any pointers/tips on what I might be doing wrong. Are there special characters that I need to escape/avoid in sending JavaScript this way (I'm using regular expression pattern matching and other code within the script which contain some special characters such as /, \, ^, etc.). Is there a limit to the size of the data that I can stream in this way? Is it as simple as loading my script /Before instead of /Doc? Anything else that I might try?
Thanks in advance for any assistance that can be given! Every time that I get to go back and spend a couple of hours updating the core library in all of these PDFs is time that I'd rather be spending doing other things. Thanks again!This sounds very intriguing and not at all along the lines of what I was thinking of. I'm glad to have the forums to be able to get different perspectives on
things like this!
I have a couple of additional questions on this. I like #3 but, not having done it before, I'm curious as to how to get it to work.
I presume that I would create a new batch process in Acrobat (I am running Acrobat Pro 9) and then on each document processed, do the following:
1. Import a PDF page (from a specified file that has the document-level scripts included.
2. Delete the page just-added
3. Save
4. Repeat, all docs specified.
Now questions:
1. I don't understand how the document scripts will be "left behind" when doing this.
2. Do I need to delete the existing document script(s) before doing this, or will they automagically be overwritten?
3. Are there any steps between the insert and the delete that I need to do?
Finally, just to add another twist, have you seen this work with PDFs that are secured (we apply a password to protect the documents from alteration, with the exception of filling out form fields)?
So far, in testing, the best method appears to be to store the PDFs separate in an un-secured format (it simply won't work if they're secured -- at least, I haven't gotten it to work yet -- I could probably do it interactively, but who wants to type the goofy password 500 times). I have a separate dummy PDF (1 page with just some explanation text if someone opens it and document-level scripts included) also stored in the folder. Then, run the batch process to do the insert, delete, then apply security on all docs in the folder. So far, so good. The only part that doesn't seem to be working is that the document-level scripts on the dummy PDF don't get left behind after the insert/delete. I removed the doc-level scripts on the original PDFs so that I could more easily verify that the ones from the dummy PDF get "left behind". I'm sure that I'm missing something simple here -- If you can help close that final gap, I'd greatly appreciate it! -
How to load a .class file dynamically?
Hello World ;)
Does anyone know, how I can create an object of a class, that was compiled during the runtime?
The facts:
- The user puts a grammar in. Saved to file. ANTLR generates Scanner and Parser (Java Code .java)
- I compile these file, so XYScanner.class and XYParser.class are available.
- Now I want to create an object of XYScanner (the classnames are not fixed, but I know the filename). I tried to call the constructor of XYScanner (using reflection) but nothing works and now I am really despaired!
Isn't there any way to instantiate the class in a way like
Class c = Class.forName("/home/mark/XYScanner");
c scan = new c("input.txt");
The normal call would be:
XYLexer lex = new XYLexer(new ANTLRFileStream("input.txt"));The problem using reflection is now that the parameter is a ANTLRFileStream, not only an Integer, as in this example shown:
Class cls = Class.forName("method2");
Class partypes[] = new Class[2];
partypes[0] = Integer.TYPE;
partypes[1] = Integer.TYPE;
Method meth = cls.getMethod("add", partypes);
method2 methobj = new method2();
Object arglist[] = new Object[2];
arglist[0] = new Integer(37);
arglist[1] = new Integer(47);
Object retobj = meth.invoke(methobj, arglist);
Integer retval = (Integer)retobj;
System.out.println(retval.intValue());Has anyone an idea? Thanks for each comment in advance!!!Dump all of your class files into a directory.
Use the File class to list all files and iterateover
the files.NastyNot really, when you are dynamically creating code, I would expect the output to be centralized, not spread out all over the place.
>
Use a URLClassloader to load the URL that isobtained
for each file with file.toURI().toURL()(file.toURL()
is depricated in 1.6)Wrong, the URL you give it must be that of the
directory, not the class file.No, I did this quite recently, you can give it a specific class file to load.
>
Load all of the classes in this directory, thatway
any anonymous classes are loaded as well.Anonymous classes automatically loaded when the real
one isIt can't load it if it doesn't know where the code is. Since you haven't used a URL classloader to load once class file at a time, you would never encounter this. But if you loaded a class file that had an anonymous classfile it needed, would it know where to look for it?
>
From this point you should be able to just get a
class with Class.forName(name)No. Class.forName uses the classloader of the class
it's called in, which will be the system classloader.
It won't find classes loaded by a URLClassLoader.got me there. -
How to load item level and location level member in demantra
This is in context where we are not using any integration of demantra with either Ebiz or E1 system.
Data is present in flat file.
As per i know, integration interface can only export the data for item level and location level but can not import data for these level.
the second thing i know is that when we create data model then load_data.bat file should have been created in Demand Planner/Desktop directory. But this didn't got created. So i am not able to use load_data.bat file for uploading data.
The third place ,i think is from worksheet thru edit method ( i am not sure about this).
But i want to upload the data in bulk for item level and location level. Can it be done without any customization i.e without creating any sql loader file etc ??Hi Abhishek,
The standard practice to load data for items/ locations and sales is through the DATA MODEL definition only. One should use LOAD_DATA.BAT file in normal scenario for loading data into Demantra staging tables from tEXT files.
In case you are having trouble with loading data using LOAD_DATA.BAT file, then do the following:
- modify your DM definition to Data tables instead of flat files
- use SQL loader to upload data in correct format into Demantra's staging tables "T_SRC_XXX"
- Run EBS Full Download workflow to download data into demantra's main tables.
Integration interfaces should not be used to load basic sales data into Demantra.
Hope this helps.
Thanks

How to load Java properties file dynamically using weblogic server
Hi,
We are using Java properties file in Java code. Properties in java properties file are frequently modified. If I keep these properties file in project classpath or as part of war, I will have to redeploy application after each change.
We are using Weblogic Server.
Can you please suggest me how can this properties file be loaded at weblogic server startup. Then in that case, how to refer property file in Java code?
What is the best practice for this?
Thanks,
ParshantAnother alternative is, keep the property file in any pre-defined location. Write a class which reads the properties from the file and returns the one which is requested by caller and deploy this class. Whenever you have to change the properties just update the property file on server and next call to fetch the property should return the updated one.
Downside of this approach is file I/O everytime. To overcome that you can actually "cache" the properties in a hashmap. Basically when any property if requested, first check the hashmap, if not found then only read from property file and also update in hash map. Next time same property will be returned from hash map itself. The hash map will be cleared at every server restart since its in the memory. You will also need to build a method to clear the hashmap when you update the values in the property file on server.
This solution would be suitable for small size files and when network overhead of calling a DB needs to be avoided. -
How to load custom root Xserve LaunchAgents on reboot
One of our new Xserve'rs is running Snow Leopard, and I have taken the plunge and started rewriting cron jobs into launchd jobs. I have the user-level jobs running just fine, and have the username/Library/LaunchAgents/.launchd.conf successfully loading launchd jobs when the system reboots.
Now, I have to run some launchd jobs as root (to permit rsync backup scripts to read/write user and system files with restrictive permissions). When I load the *plist files manually as root, all is good. But I haven't found out how to load root-level *plist files on reboot. I have tried putting the *plist launchd jobs in /System/Library/LaunchAgents, and I have tried putting them in the root user /var/root/Library/LaunchAgents with the accompanying .launchd.conf file.
How do I get my launchd jobs that need to run as root to load on reboot?Dave,
I am by no means an expert, but on Leopard server I have used Lingon to configure the regular script calls I needed (I had used cron jobs so had to switch when upgrading to 10.5). It has an assistant to create the plist files and knows where to put them and I believe it did for me what you are looking for.
Cheers,
Michael. -

How to remove xmlns in node level
Hi Experts!
How to remove xmlns in node level in response xml file. I tried to use AF_Modules/XMLAnonymizerBean, but it did not work.
Can you please help me out on this.
I want to remvoe xmlns tag in LEVICOM
Eg:
- <Addenda>
- <LEVICOM xmlns="">
Thanks,
HariHi Expers!
Please help me out on this. The below xslt mapping working only to remove xmlns prefix in xml file, if parent having only one child. This code is not working if parent having multiple childs.
Eg: <parent>
<phild xmlns="">
test1
</phild>
</parent>
The above example working fine with below xslt mapping to remove xmlns tag.
Second scenarion not working
Eg: <parent>
<child1 xmlns="">
test1
</child1>
<child2 xmlns="">
test2
</child2>
</parent>
The above example is not working.
Here is the code:
You can remove the namespace prefixes using an XSLT mapping if they are causing problems with applications outside of XI.
Try the following code:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns="http://www.arconw.com/XI/XSLT_Library/XmlNamespacePrefixRemoval"

</xsl:template>
<xsl:template match="*" mode="remprefix">
<xsl:variable name="newname" select="local-name(.)"/>
<xsl:element name="{$newname}" namespace ="{namespace-uri()}">

Row Selection for second and subsequent level nodes in tree table
Hi All,
We have a .jsff page with tree bindings to display a three-level hierarchy tree table.Suppose the hierarchy is
-> Department
->-> Employees
->->-> Employee details.
I have a use case where-in when we add the employee node within a department,the department node must expand and the newly added employee node must be selected.
In both the cases(for new department or employee), we are following the approach mentioned below:
1. Get the treeTable Iterator.
2.Adding the new object to the java ArrayList which is bound to the corresponding level in the tree.
3.Refreshing the treeTable iterator.
4.Execute treeTable.setSelectedRowKeys()
5.Add a partial target to the treetable.
The issue is that the new employee gets added but the upper-level department node collapses and no selection is performed on the new employee node.
But when we add a new department node, it gets selected on creation.
Is there any additional steps to be performed for second-level row selection?Hi,
Thanks for the reply.
I looked at the code given in sample 61.
In the sample, a new node is not added dynamically (for ex.either new location or its child nodes.)
As mentioned in the above post, after adding a new node at a level in our use case, when we perform the refresh of the tree-table's iterator,the selection state of the rows is not shown on the table.
If the tree-table's iterator is not refreshed and the treeTable.setSelectedRowKeys() is executed, the rows get selected but the subsequent node additions do not show up in the table as the table's iterator is not refreshed.
Any sample code is available where in both the addition of new node and its selection is performed at the same time?
Thanks. -
How to create second or third level of menu bar in se41 ?
Hi All
How to create second or third level of menu bar in se41 ?
I created it once but forgotten , do anybody remember ?
Regards
Jaman
Message was edited by:
ABAP TechieHi..,
Once you have created a menu bar, you enter the individual menu entries. Each menu can contain up to 15 entries.
A menu can contain any of the following:
Function names (with function code and text)
Submenus (pull-down menus)
Separators
You may include submenus up to three levels deep.
Menu functions that logically belong together are grouped together using separators. This makes the menu easier to use. Separators also make long menus easier to read by dividing them into smaller parts.
Defining Menu Functions
To add functions to a menu that is already open in the Menu Painter:
Open a menu list in the menu bar by double-clicking the menu title.
The system opens the menu. The menu entries list contains the two columns Code and Text.
In the Code column, enter a function code (this may be up to 20 characters long).
If you want to enter a function code that is longer than the input field, you must first change the displayed length of the field in the user settings. (Choose Utilities ® Settings ® User-specific.)
Enter the function text in the Text column.
The name you enter here appears in the menu at runtime. You can also determine the contents of function texts at runtime (see Defining Dynamic Function Texts).
Repeat steps 2 and 3 for each item in the menu.
Creating Cascading Menus
To add a cascading menu (sub-menu) to a menu:
Leave the Code column blank.
Enter a menu name in the Text column.
Double-click the cascading menu to open it.
The system opens the menu entry list for the cascading menu.
Complete the menu as you would any other.
Inserting Separators
Place the cursor on a line.
Choose Edit ® Insert ® Separator.
If you want to insert a separator between two existing menu entries, place the cursor on the line before which you want to insert the separator.
Editing Menu Entries
You can cut, copy, paste, and delete menu entries.
Place the cursor on a line.
Choose Edit ® Entry ® Cut (or Copy, or Paste, or Delete).
If you double-click a function code, the Function Attributes dialog box appears. Here you can, for example, change the icon assigned to a function.

I have this code loading a set of thumbnails. Right now the
first set of thumbs loads fine but how to load my second array in a
new row?Well my first idea would be that somewhere you are out of
scope and therefore you are getting an undefined somewhere in your
code.
So it might be trying to pass "undefined" as your url.
I would start with the debugger and step through the code to
make sure that it is able to get all the values it needs at every
step.
A good understanding of the debugger tool will save you tons
of time.
My next idea would be to split the code up using the command
pattern.
Also, since you only have two arrays, you could put an if
statement before incrementing the arr variable.
example:
if (arr < 2){
arr++;

How get context value form a dynamic created node

How can I read my Node row for row?

Edited by: Armin Reichert on Jul 28, 2008 5:03 PMThe reason is that all these Caption UI elements are bound against the same context attribute. At runtime this will be resolved to the attribute value of the lead-selected node element. In this example you can fix this by not binding the "text" property but setting it to the attribute value of the iterated node element:
for (int x = 0; x < dynTabNode.size(); x++)
dynTabNode.setLeadSelection(x);
IWDGroup group = (IWDGroup)view.getElement("Group_name");
IWDCaption name = (IWDCaption) view.createElement(IWDCaption.class, null);
IWDNode dayNode = wdContext.getChildNode("DayNode", IWDNode.LEAD_SELECTION);
String text = (String) dayNode.getElementAt(x).getAttributeValue("Name");
name.setText(text);
IWDAttributeInfo aiName = dayNode.getNodeInfo().getAttribute("Name");
name.bindText(aiName);
group.addChild(name);
(I assume here that the node "DayNode" has the same size as dynTabNode. No idea if this assumption is correct)
But this would not help for editable elements where you need to bind the edited property.
