Java Comm API on Linux - run error

I installed the Java Comm API on Linux per the instructions on the web site. The SimpleWrite.java file compiles OK, but when I run it I get the following error:

Exception in thread "main" java.lang.NoClassDefFoundError: SimpleWrite

Can anyone please explain what I am doing wrong?

TIA,

David Evennou

OK, thanks! At first I was getting compile errors, then I added the comm.jar file to the $CLASSPATH environment variable. The java file then compiled OK, so I thought the Classpath was set correctly. Obviously, I need to learn more about Java Classpaths:)

(converting from C++ to Java)

Thanks,

One thing to learn is not to use the variable at all, but the -cp/-classpath arguments of java/javac.
