Hi!

I'm trying to make a JAR-File from my classes. That's fine so far but
when I try to start the class with the main-method I get the following
message:

Exception in thread "main" java.lang.ClassFormatError: --------/-------
:-)
(Bad magic number)
at java.lang.ClassLoader.defineClass0(Native Method)
at java.lang.ClassLoader.defineClass(Unknown Source)
at java.security.SecureClassLoader.defineClass(Unknown Source)
at java.net.URLClassLoader.defineClass(Unknown Source)
at java.net.URLClassLoader.access$100(Unknown Source)
at java.net.URLClassLoader$1.run(Unknown Source)

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

Can anyone tell what this means and/or how to avoid it?

see error messages in the Java glossary.

Answers to the four most frequent questions:
Please consult the Java glossary:
1) for conversion problems, see "conversion". .
2) for I/O problems, see the "File I/O Amanuensis" and "File".
3) if you want to create a *.exe, see "native compiler".
4) if you are new to Java, see "getting started"
