Executing Class File in Ubuntu!

[nitish_mythology]

I am coding in JCreator(Windows) and now I want to execute the class file in Linux..
Dont know exactly if I have jdk or jre insatlled..

Here is the output of java -version

nitish@Nitish:~$ java -version
java version "1.4.2"
gij (GNU libgcj) version 4.1.2 (Ubuntu 4.1.2-0ubuntu5)

This is what i did to execute the java ByteCode

nitish@Nitish:~/Development$ java linear
Exception in thread "main" java.lang.ClassFormatError: linear (unrecognized class file version)
at java.lang.VMClassLoader.defineClass(libgcj.so.70)
at java.lang.ClassLoader.defineClass(libgcj.so.70)
at java.security.SecureClassLoader.defineClass(libgcj.so.70)
at java.net.URLClassLoader.findClass(libgcj.so.70)

at java.lang.ClassLoader.loadClass(libgcj.so.70)
at java.lang.ClassLoader.loadClass(libgcj.so.70)
at gnu.java.lang.MainThread.run(libgcj.so.70)

Do i need to secify path?? I am already working in the directory that contains the class file.


PS:I hope the section is correct! Mayb it shd have been in Open Source!

I do not know about the problem, but its better if you use Sun Java JDK 6 than GCJ (GNU tools).

I have exceeded my monthly Bandwidth usage so I dont want to download anything right now..will have to wait till June!

Or work in Netbeans (with JDK installed).... If you don't get enough bandwidth to download you can order a free DVD too from Netbeans.org

Ya i have ordered it.. Seems I wll have to wait for a few days if I cant work on GCj.
