IBM J9 JDK in Eclipse

Instructions for setting up the Windows edition of the IBM J9 JDK for local development of mobile applications in Eclipse.

1. Install the IBM J9 JDK for Windows (aka WEME - "Websphere Everyplace Micro Environment").

2. Look for, and unzip weme-win-x86-ppro11_6.1.1.20061110-161633.zip into an empty directory. I chose c:\weme-6.1.1 - just change the references below if you choose a different directory.

3. From Eclipse, go to Windows, Preferences, Java, Installed JREs and click Add.

4. Browse to the directory that was unzipped to earlier (c:\weme-6.1.1).

5. You will get an error message : "Target is not a JDK Root. Java executable was not found"

6. To fix that, copy c:\weme-6.1.1\bin\j9.exe to java.exe in the same directory

7. If you try Step #3 again, you will get another error message : "Target is not a JDK Root. System library was not found."

8. Not a problem : just create the directory c:\weme-6.1.1\jre\lib and copy
c:\weme-6.1.1\lib\jclFoundation11\classes.zip to c:\weme-6.1.1\jre\lib\rt.jar

9. There should be no further complaints from Eclipse at this point.

10. Enter a name for the JRE, let's say, weme-6.1.1

11. Uncheck "Use default system libraries", click Add External Jars, and add the required libraries :

12. Select weme-6.1.1 as your default JRE, click OK, and your project will now re-compile under the J9 JDK.

13. If you try running your application, you will get this error message :

JVMJ9VM011W Unable to load jclfoun10_23: The specified module could not be found.
JVMEXEX013E Internal VM error: Failed to create Java VM
JVMEXEX014I Run C:\weme-6.1.1\bin\java.exe -help for usage

14. Go back to Installed JREs and edit your weme-6.1.1 JRE

15. Under Default VM Arguments, add -jcl:ppro11
