Java VM version

Hi all,

I'm trying to use some java classes in some cocoa code I wrote. I succeed in loading the classes, but when calling a method I get an error: (Unsupported major.minor version 49.0). I know this happens because the JavaVM tries to load some code compiled for a different java version. In this case the 1.3 java vm tries to load java 1.5 code.

In normal bundle applications I know I can change the vm version to use by setting the JVMVersion key in the Info.plist file. But at the moment I use the java code in a framework, and setting the JVMVersion doesn't seem to work, resulting in initializing a Java 1.3 VM instead of a 1.5 VM.

At the moment I try to use my framework in a OCUnit bundle, so setting the JVMVersion key in the Info.plist of the final application which is going to use my framwork will not work. Is there a way to programatically load a java 1.5 or 1.4 VM instead of loading the default 1.3 vm without setting the JVMVersion?

Thanks,

Joris Kluivers
