java self-contained application packaging cracking

[Chuck954]

I have an app that uses a JAR file for security. It used to open up javaw.exe. Working on cracking a newer version and it looks like it uses a self-contained application packaging. That's what I think this is. If it just used javaw.exe I could attach a java debugger.

The program now uses DLL files to access the JAR file. Anyone know of a way to attach a java debugger to something like this? Any suggestions?

I've decrypted the JAR file but it but it'd be nice to be able to manipulate the data in real time.

It sounds unclear that this new version has anything to do with Java. After all a JAR is just a ZIP archive with a special Metadata folder and Metadata files. If DLLs are being used and Javas executables are not running, then it would been to be reversed like any native code app.
