Hello,

Created .exe file from an executable jar file with Launch4J UI application.

After creation I am able to extract the .exe content with winrar tool.

Please help to understand how to prevent the .exe file content extracting with tools/commands.

Thanks & Regards,
Kumar

Hello,

Launch4j does not protect jars from being extracted, it's a tool for running Java applications in the Windows environment in a more controlled way. The files which it produces are still jars.

Hi Kumar,

Personally I'd recommend http://proguard.sourceforge.net, it does not protect the jar but makes the code very difficult to reverse-engineer.
