Event Handling with Java API.: Adding to a hierarchy table throws 2events

I´m having some problems with the event handling. I´ve registered a Class with extends AbstractDataListener as EventListener. When there are changes in the product hierarchy table, some extra work should be done. However if i add a new record into the hierarchy, two events are fired.
DEBUG DataEventListener.java:123 - Added:Development;PRODUCT_HIERARCHY;R17;Getra?nke, SEW
DEBUG DataEventListener.java:123 - Added:Development;PRODUCT_HIERARCHY;R17;32 Zoll, B&R
DEBUG DataEventListener.java:123 - Added:Development;PRODUCT_HIERARCHY;R18;56 Zoll, Lenze
DEBUG DataEventListener.java:123 - Added:Development;PRODUCT_HIERARCHY;R18;20 Zoll, allgemein
In this case, i added the records "32 Zoll, B&R" and then "20 Zoll, allgemein". As you can see in both cases two events are fired and the first event seems to come with wrong data. The reported id for the newly created record is R17. For the logging, i did lookup the entry in the hierarchy table by id and use the displayvalue of the record. But the first event always shows the displayvalue from some already existing entry.
How can i avoid duplicate events or if this is not possible, how i can recognize that the display value of the first event is not valid.

I have not tetsted it yet, because I'm waiting for my server to be updated, but SAP told me that the API version 5.5.42.67 should fix the problem.
Thanks for your post.

Events problem with (Java and ActiveX)

Hi,
I use an ActiveX component with Java and i've got a problem with events.
Java classes were generated with Bridge2Java (IBM).
In order to manage events I added a listener in my application :
javaMyActiveX = new MyActiveX();
javaMyActiveX.add_DMyActiveXEventsListener(new _DMyActiveXEventsAdapter());
I also added a constructor in the _DMyActiveXEventsAdapter class and I fill the body of methods.
The ActiveX generates two types of events :
- The ones are directly generated by methods.
- The others are generated by a thread.
With MS Products (VB, Visual C++, Visual J++), I catch all events.
With java (jdk 1.4), I catch only events generated by methods.
Can anyone help me.

I'm not 100% sure, but the last time I used that bridge, it only worked if you ran your Java app within a Microsoft VM.

Attaching/Detaching libraries with Java API

Hello,
In my forms (Forms10g), sometimes, libraries had been attached in lower case although files are in upper case. This causes compilation errors on UNIX systems.
I'm trying to detach these libraries with Java APIs and then reattach them in upper case.
But I get an error when I want to save the module.
Here is my code :
public class UpperPll {
     public UpperPll (String formName) {
          try
               FormModule form = FormModule.open("C:/AttachPll/" + formName);
               System.out.println("Form Name is " + form.getName());
               JdapiIterator AttachPll = form.getAttachedLibraries();
               while(AttachPll.hasNext())
                    try
                         JdapiObject jo = (JdapiObject)AttachPll.next();
                         System.out.println(jo.getName());
                         if (jo.getName().toLowerCase().equals(jo.getName()))
                              AttachedLibrary.find(form,jo.getName().toUpperCase()).detach();
                              System.out.println(jo.getName().toUpperCase());
                              new AttachedLibrary(form,jo.getName().toUpperCase());
                    catch (JdapiIllegalStateException jdise)
                         jdise.printStackTrace();
               form.save("C:/AttachPll/New/" + form.getName() + ".fmb");
               Jdapi.shutdown();
          catch (JdapiException jde)
               jde.printStackTrace();
     public static void main (String[] args) {
          try {
               FileReader r = new FileReader( "C:/AttachPll/listemodule.txt" );
               BufferedReader br = new BufferedReader( r );
               try {
                    String module;
                    while ( ( module = br.readLine() ) != null ) {
                         new UpperPll(module);
               } finally {
                    r.close();
          } catch (FileNotFoundException fnfe) {
               fnfe.printStackTrace();
          } catch (IOException ioe) {
               ioe.printStackTrace();

We do something very simular. We rename everything to lowercase for the same reasons. I've pasted a snippet of the code we're using at the end of this post.
To get the full source code of our converter have a look at http://www.oratransplant.nl/2005/05/30/custom-built-forms-migration-assistant/#comment-642
Here is the code snippet:
while (attachedLibs.hasNext()) {
AttachedLibrary attachedLib = (AttachedLibrary)attachedLibs.next();
String attachedLibLocation = attachedLib.getLibraryLocation();
out("Found attached library " + attachedLibLocation, logLevel,
false);
if (attachedLib.getName().equalsIgnoreCase("obsolete_forms6")) {
obsoleteAttached = true;
if (attachedLib.getName().equalsIgnoreCase("webreports")) {
webReportsAttached = true;
// converted name of attached lib to lowercase
if ((!attachedLibLocation.equals(attachedLibLocation.toLowerCase())) &&
lowerLib) {
out(attachedLib,
"Converting filename to lowercase (" + attachedLibLocation.toLowerCase() +
")", logLevel + 1, true);
attachedLibLocation = attachedLibLocation.toLowerCase();
pllChanged = true;
// attachedLibLocation = attachedLibLocation.toUpperCase();
pldText.append(".attach LIBRARY " + attachedLibLocation +
" END NOCONFIRM\n");
out("Re-attaching library " + attachedLibLocation, logLevel + 1,
false);
}

Read "Qualified Range Key Generation" with Java API.

Hi guru,
I use MDM 5.5 SP6.
In MDM Console I read Qualified Range Key Generation it in "ADMIN -> Remote Systems -> Qualified Range".
I have to get "Qualified Range Key Generation" with Java API.
It's possible?

Hi Rocco,
I am also thinking of same scenario.I thought it is possible in Java Apis by calling the webservices for MDM.there is a service of "get key mapping" where we can pass this "Qualified key range" as parameter.In MDM we have to define a look up table for that key ranges .We will access that table through JAVA API and then link it with the key mapping service .
If u find any solution to apply this ,please share.
thanks and regards

Bursting with JAVA APIs / MultiThreading / Errors Handling

We are trying to use the bursting JAVA APIs 10.1.3.3.1 Standalone) to burst huge XML files and generate PDF Files from RTF templates. Here are a list of our issues with this feature:
1. We have some problems catching the errors when bursting. We have tried to use the "oracle.apps.xdo.common.log.Logger" class, but it is not always reacting like we think it should. Could you please give us an exemple of a clean bursting error catching or a brief description of how we could do it. We have a lot of difficulties to find information about using the JAVA APIs of BIP.
2. Is it a clean way of catching the bursting errors to use the "oracle.apps.xdo.common.log.Logger" class?
3. When using the 10.1.3.3.1 DocumentProcessor JAVA API, the process gets killed when the RTF template is not where the control file specified it. Even when using a finally clause containing the document processor, we can't fetch the error from the "oracle.apps.xdo.common.log.Logger" class. We did not find a way to catch this error which make our program crash.
4. How can we enable multi-threading that is included in the DocumentProcessor JAVA APIs so it can take advantage of the multi-processors environnements?

1. Check tim d. blog, you can use the bursting listners to get the errors. It's also in the documentation.
First, on every exception, the Bursting APIs are dumping the error in the Logger. So I can't see how we can use the listeners to catch these. We can check the hasExceptions on the Logger but still, we have some problems with this. When we deploy our application as a MDB (Message driven bean), it seems that once the hasException flag has been raised, if we call the MDB again, it is still up. Is there documentation about that Logger class? Also, I'm worried that we won't be able to call our MDB twice to run simultaneously 2 different bursting process since it seems the Logger is something static, keeping every exception in memory... That's bad.. And show me where you have found documentation about this. All I see in documentation is how to call the DocumentProcessor in a couple of lines. I don't see anything about a clean way to catch errors.
2. Yes/No/Depends. I think it's fine. If your changing the logger options in your program that could come back to haunt you.
I guess so, I'm not changing anything and its already haunting me...
3. When using the 10.1.3.3.1 DocumentProcessor JAVA API, the process gets killed when the RTF template is not where the control file specified it. Even when using a finally clause containing the document processor, we can't fetch the error from the "oracle.apps.xdo.common.log.Logger" class. We did not find a way to catch this error which make our program crash.
Even worst, when we deploy the component has an MDB, when the error happens, it kills the whole oc4j container... please correct this quick.
4. How can we enable multi-threading that is included in the DocumentProcessor JAVA APIs so it can take advantage of the multi-processors environnements?
We got an answer from the dev team which is to add two properties to the document processor, something like:
enable-multithreading: true
thread-count: >2
We did that and what we got is that the process started and it got stuck in a dead lock at the first document processing. How nice! :)
We got a milestone in March and I'm really worried about all those problems... Not enough documentation, a pretty bad error handling, errors making crash the whole oc4j container, Logger seems not to be handling simultaneous calls/ threads, not even handling two subsequent calls... etc.
If anyone has the magic answer, it would be pretty welcomed!
Thanks

        frame.setVisible(true);     // displays frame
}p.s. sorry about the untidy comments!

OK, so you've got this code here:
private class ButtonListener implements ActionListener {
public void actionPerformed (ActionEvent e) {
    if (e.getSource () == exit) {
      System.exit(0); // exits the GUI
    if (e.getSource () == snam) {
    if (e.getSource () == id) {
}Perfect fine way to do this; although I think creating anonymous would be a bit cleaner:
snam.addActionListener(new actionListener() {
public void actionPerformed(ActionEvent ae) {
});But I think that the real question you have is "what do I put for logic when the JButtons are hit?", right?
I would answer that you want to dynamically build your SQL statement changing your ordering based on the button.
So you'd have a method that builds the SQL based on what you pass in - so it takes one argument perhaps?
private static final int NAME = 1;
                         ID = 2;
/* ... some code ... */
snam.addActionListener(new actionListener() {
public void actionPerformed(ActionEvent ae) {
    buildSQL(NAME);
/* ... some code ... */
private void buildSQL(int type) {
if ( type == NAME ) {
/* ... build SQL by name ... */
else if ( type == ID ) {
/* ... build SQL by id ... */
}That kind of thing.
Or you might choose to have several build methods with no parameter type; each building the SQL differently, and calling whichever one you need. I did not read your entire pgm, so I don't know how you'd want to organize it. You need to ask more specific questions at that point.

Difference in event handling between Java and Java API

could anyone list the differences between Java and java-API in event handling??
thanks,
cheers,
Hiru

the event handling mechanisms in java language
features and API (java Application Programming
Features)features .no library can work without a
language and no language has event handling built in.
I am trying to compare and contrast the event
handling mechanisms in the language and library
combinations such as java/ java API.
all contributions are welcome!
thanks
cheersSorry, I'm still not getting it. I know what Java is, and I know what I think of when I hear API. (Application Programming Interface.) The API is the aggregation of all the classes and methods you can call in Java. If we agree on that, then the event handling mechanisms in Java and its API are one and the same.
So what do you want to know?

How do I resolve connection error with Java API listener?

I have created a listener using the new Java API (see How do I implement a listener using new MDM Java API? for background). When I run it, I get this error message
Mar 19, 2008 3:57:58 PM com.sap.mdm.internal.net.ConnectionImpl finalize
INFO: Disconnect was not called. Cleaning up connection in finalize.
This message is triggered whenever I generate a data event that I would otherwise expect to be captured and handled by the listener. I have tried a number of things, including setting the connection to NO_TIMEOUT and trying SimpleConnection versus ConnectionPool, but always with the same result.
Here is some sample code for the listener:
public class DataListenerImpl implements DataListener {
     public void recordAdded(RecordEvent evt) {
          System.out.println("===> Record Added Event");
          System.out.println(evt.getServerName());
     public void recordCheckedIn(RecordEvent evt) {
          System.out.println("===> Record Checked In Event");
          System.out.println(evt.getServerName());
     public void recordCheckedOut(RecordEvent evt) {
          System.out.println("===> Record Checked Out Event");
          System.out.println(evt.getServerName());
     public void recordModified(RecordEvent evt) {
          System.out.println("===> Record Modified Event");
          System.out.println(evt.getServerName());
And here is the code for the Event Dispatcher:
public void execute(Repository repository) {
     DataListener listener = new DataListenerImpl();
     try {
          EventDispatcherManager edm = EventDispatcherManager.getInstance();
          EventDispatcher ed = edm.getEventDispatcher(repository.getServer().getName());
          ed.addListener(listener);
          ed.registerDataNotifications(SystemProperties.getUserName(), SystemProperties.getPassword(),
                    repository.getIdentifier(), repository.getLoginRegion());
          ed.registerRepositoryNotifications(SystemProperties.getUserName(), SystemProperties.getPassword(),
                    repository.getIdentifier());
          ed.registerGlobalNotifications();
          while (true) {
               Thread.yield();
               try {
                    Thread.sleep(1500);
               } catch (InterruptedException ex) {
                    System.out.println("Interrupted Exception: " + ex.getMessage());
     } catch (ConnectionException e) {
          e.printStackTrace();
     } catch (CommandException e) {
          e.printStackTrace();
Has anyone else encountered this message? Could it be related to a TCP configuration on the server? Or is this a bug in the Java API?
As I mentioned in the forum posting linked to above, I have not encountered this problem with the MDM4J API.
Any help is greatly appreciated.

I resolved it. We are switching over to SP6, Patch 1 and the listener code works fine with this version of the Java API.
Just one thing to note, though: make sure that you register data notifications through MetadataManager in your initialization code:
metadataManager.registerDataNotifications(userSessionContext, repositoryPassword);
For information on the changes to the SP6 Java API, especially with regard to connecting to MDM with the UserSessionContext, please review Richard LeBlanc's [presentation|https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/20073a91-3e8b-2a10-52ae-e1b4a10add1c].

Insert Value(s) in Lookup Flat Multi-valued Table with Java API

I've been looking in MDM Java API Library Reference Guide, MDM SP4 API JavaDoc, and SDN Forums for information on how to Insert/Update different values in a field in the Main Table of a given repository that belongs to a Lookup Flat Multi-valued Table using the Java API with no success.
I also haven't been successful in adding this values in the same way that I'll add a single value, using the MDM Java API, in a single-value Lookup Table (a2iFields.Add(new A2iField(FIELD_CODE,FIELD_VALUE)) for each value I want to add, like for example:
a2iFields.Add(new A2iField("Country","USA")
a2iFields.Add(new A2iField("Country","Mexico")
a2iFields.Add(new A2iField("Country","Germany")
Can anybody point me to the correct documentation that I need to read to fulfill this task? Or, even better, if someone can post a piece of code, I'll be more thankful.
Thanks for your help.

HI,
little code example, where you add existing lookup values based on there record id:
     int USA = 1;
                    int GERMANY = 2;
                    A2iValueArray countryArray = new A2iValueArray();
                    countryArray.Add(new Value(USA));
                    countryArray.Add(new Value(GERMANY));
                    A2iFields record = new A2iFields();
                    record.Add(new A2iField("Country", new Value(countryArray)));
Please reward points if helpful.
Regards,
Robert

C# control event handling with javascript

How can I get javascript to execute for "onchange" / "OnSelectedIndexChanged" event instead of a CodeBehind method? I think "OnSelectedIndexChanged" event has to be handled by CodeBehind; but how can I replace that (or onchange) with
a javascript event handler?
I have the following in my xyz.ascx file:
<asp:DropDownList ID="ddlTypeCar" CssClass="BatsRefAddressTypes" runat="server"
                  onchange="javascript: testAlert();"
                  OnSelectedIndexChanged="ddlTypeCar_SelectedIndexChanged"
                  AutoPostBack="True" />
I could not get the javascript to execute, even though I removed OnSelectedIndexChanged="ddlTypeCar_SelectedIndexChanged" and/or set AutoPostBack="false".
Additionally, I tried added the following in xyz.ascx.cs Page_Load() method.
ddlTypeOfAddress.Attributes.Add("onchange", "javascript: testAlert();");
which didn't help.
Thanks for your help in advance.

Event Handling in C API

Does Internet Directory C API supply the event handling like those in JNDI? Actually Netscape Directory/IBM Secuway Directory supply this features for C SDK, why Oracle Directory Server do not supply it?
Thanks,

Hello Peter:
Have you seen the "Oracle Internet Directory v2.1.1 Application Developers guide"? In chapter 2 there is a section on error handling. Let me know if this answers your question.
Thanks,

Event handler if new File added in current folder

Hi folks,
I'm just trying to write a little jsx script for Bridge CS6.
How can I implement an event handler that will react if the user adds a new thumbnail (new file) to the current folder in bridge.
I've tested it with this code, but it doesn't work:
app.document.thumbnail.watch ("children", function(id, oldVal, newVal) {
$.writeln (oldVal + " to " + newVal);
// some code here
Thanks. Greetings

Beautiful. Works as advertised. Thank you for pointing it out to me. Unfortunate that a basic subset of this extension's behaviour doesn't ship with Thunderbird out of the box, though.
