Hello, I am a new user and I am having some problems running Examples.java file. Could someone please give me a hand?

I set the classpath to two jar files, and compilied using javac Examples.java. That was Ok.

But when I run it, it returns me the following error message:

Exception in thread "main" java.lang.NoClassDefFoundError: Examples (wrong name: net/didion/jwnl/uti
        at java.lang.ClassLoader.defineClass0(Native Method)
        at java.lang.ClassLoader.defineClass(Unknown Source)
        at java.security.SecureClassLoader.defineClass(Unknown Source)

        at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
        at java.lang.ClassLoader.loadClass(Unknown Source)
        at java.lang.ClassLoader.loadClassInternal(Unknown Source)

there are two Examples.java file, one under root directory, the othe under net/didion/jwnl/uti
lities/ directory, which one should I be using? What have I done wrong so far?

Thanks a lot!

Best regards,
