Question

Hi,
we are using the Java Connector, and I can add or update Business Partners.
But adding or updating an JournalVouchers allways throws the following COM Exception
on a SBO 6.5. Our programm-code works on a SBO 6.2, but not on a SBO 6.5 ?
What is wrong ? Can anybody tell us that ?

Answer 1

After a long search I have found the answer to this proproblem myself on service.sap.com/smb note-no 706379. I have tryed it out and it WORKS. Please read the following text that explains the problem and the solution :
Symptom
Following exception or similar text found in the failed response message
COM exception has been encountered: At Invoke of: Add
Description: The server threw an exception.
Other terms
SBO ITK, Java Connector, SBO SDK, DI-API, SAP J2EE 6.20
Reason and Prerequisites
Note 642676 explains this problem in a detail.
In a brief, the main stack size is not large enough causes this
exception.
Solution
First of all, please find from which exe file the J2EE server started. For starting in the console with go.bat, the exe may be java.exe under %JAVA_HOME%\bin (Please check the path setting for which java.exe
to be used. Normally, it may be C:\WINDOWS\SYSTEM32\java.exe,
%JAVA_HOME%\bin\java.exe, %JAVA_HOME%\jre\bin\java.exe,
or C:\Program Files\JavaSoft\JRE\1.3.1_08\bin\java.exe)
For starting as the windows service, you can find the exe as following:
1. Open the service from Start -> Setting -> Control Panel ->
   Adiministrative Tools -> Services
2. Find the service to start SAP J2EE 6.20 of ITK, for example,
    "SAP J2EE Engine Alone"
3. Open the properites window of this service, you can find the exe    in "Path to excutable", for example,    d:\SAP_J2EEngine6.20\configtool\alone.exe
Second, prepare the tools to do the patch. If you have installed
Microsoft Visual Studio 6.0, you have the right tools. We need
a. editbin.exe, to patch the exe.
b. dumpbin.exe, to check the stacksize.
c. link.exe and MSPDB60.DLL to run above two tools.
Third, patch the exe:
1. BACKUP THE ORIGINAL EXE, JAVA.EXE OR ALONE.EXE
2. Use dumpbin.exe to check the original stack size
   dumpbin.exe /headers alone.exe
   find line: 40000 size of stack reserve
   It means the current stack size is 256k
3. Use editbin.exe to patch the exe, for example with 2m stack size
   2m = 2 * 1024 *1024 bytes = 2097152 bytes
   editbin.exe /stack:2097152 alone.exe
4. Use dumpbin.exe to verify the patch.
   dumpbin.exe /headers alone.exe
   find line: 200000 size of stack reserve
   It means the current stack size is 2m
Last step, start the J2EE server again and see whether everything
is OK.
For service, we also recommend you patch    d:\SAP_J2EEngine6.20\configtool\service.exe All installed service exe file, for example alone.exe will be copied from this file. Patch this file will avoid patch each duplicated exe file then.
