java webstart decompiler

Question

Is there anyway to decompile java webstart application?

Answer 1

Start the application, then fetch the JAR(s) from the webstart cache. Proceed to decompile like with any other Java application.

Answer 2

Yes, there is. A Java Webstart application is just one form of deployment. The result is a bunch of jars copied to the users home directory. And these can of course be decompiled for example with jad.

Answer 3

And what about that bunch of jars doesn't exist? I'm analyzing an applycation that copy a bunch of dirs named by numbers secuencially, having randomly named files, some of them are .idx (java cache index?)

How can I get the jars?

Answer 4

Just rename the files with a .jar extension :)
