jar cvfm *.class META-INF/*

with the manifest like this:
Class-Path: /usr/utils/utils.jar

I get this error from the jar tool: "invalid header file".
Do you know how to overcome this problem ?

Also I tried to build the jar file in Windows using winzip but when I invoke the bean that use utils classes then I get another error: "Illegal access error".

Any clue?
Thanks
Francesco
