Author Topic: Java don't works (Read 6576 times)

Hello,
I've written javacode, but it doesn't work:

Quote

public static void main(String[] args) {
   Repository r = new org.sparx.Repository();
   if (r.OpenFile("c:\\Example.EAP")==true) {

   //here is the action
   r.CloseFile();
   } else {
   System.out.println("EA-Project not found");
   }

Open the file works, but I can't get anything in there. Anytime I get a nullpointerexception. For example when I use the following things:
Collection<org.sparx.Package> c = r.GetModels();
org.sparx.Package pack = c.GetAt((short)0);
r.GetModels().GetCount(); is not working, everything is null...I'm completly frustratet.

In VBA it works in a simple Excel-Macro...

I have had the same problem...
1) make sure you don't have any EA processes running for you first run.
2) make sure you close the repository correctly

repository.CloseAddins();
repository.CloseFile();
repository.Exit() //fails sometimes
repository = null;

You can also call GC after this.

What build of EA are you using?

If you're not using the latest 7.1 (or the 7.5 beta) try upgrading to that build. I am aware of issues where the Java API didn't work on some builds.

I use version 7.1.827

Then upgrading to the latest build should help.

I've tried with 7.1.834 .... no success.

Did you upgrade using the installer of the patch file?

If it was the patch file, did it include the SSJavaCOM.dll file?

What are your SSJavaCOM.dll and eaapi.jar files dated?

Have you checked if there are any EA processes still running? If you don't shut down properly, a process will keep running and cause problems for later processes. Kill all EA processes in Windows task manager or restart Windows.

@simon: the installation process uninstalled the old version and installed a complete new one. File date ist 05. august 2008.

@lars: no other instance running.

Eve · « **Reply #10 on:** February 16, 2009, 08:27:33 am »

The date of SSJavaCOM.dll should be 13 October 2008.

I've got your support request, I'll send you the 834 files via email.
