I have a pretty old exe but no java source code anymore. Unfortunaltey I have to change something within this application. It is not a simple jar file. It has been packed to an exe with exe4j.
Is there an easy way to extract the class files ?
I tried some ressource hacker apps but the classes are not packed as ressources. Any more ideas ?

Thank you
