Hey

I have installed this on my fresh 10.2 with no problems. I can compile hello world but when I come to run it I get:-

Exception in thread "main" java.lang.ClassFormatError: HelloWorld (unrecognized class file version)
   at java.lang.VMClassLoader.defineClass(libgcj.so.7)
   at java.lang.ClassLoader.defineClass(libgcj.so.7)
   at java.security.SecureClassLoader.defineClass(libgcj.so.7)
   at java.net.URLClassLoader.findClass(libgcj.so.7)
   at java.lang.ClassLoader.loadClass(libgcj.so.7)
   at java.lang.ClassLoader.loadClass(libgcj.so.7)
   at java.lang.Class.forName(libgcj.so.7)
   at gnu.java.lang.MainThread.run(libgcj.so.7)

....Looks like im still using the gcj version that came pre-installed.


javac - version gives me

javac 1.6.0_01 

which sounds right, BUT

java -vesion gives me :-

gij (GNU libgcj) version 4.1.2 20061115 (prerelease) (SUSE Linux)

I guess I need to change this so it uses the version I installed with my SE install, any pointers as to how to go about this, been smashing my head against the keyboard ALL night

Thanks

Joe

I usually uninstall gcj and all of its components because its not really needed if you are going to be using Sun java.
