How to get source code from the cap file

[leogen]

I am given a CAP file. Is there any way to get source code from the cap file ?

[gorgekin]

IMO, there is NO way to do this!

as i know, there is a component named normalizer in JCKit3 (located in tools.jar) can generate some kind of .class file(s) as inter-midia.

maybe you can use this tool as a start point. refer to <JCDevKitUG-Classic-3_0_4.pdf> chapter 6.

and, i googled at 2011 or more earlier, there is an open source project hosted in code.google.com, can do this job, but it only existed in the google's cache. so i failed to checkout it.

It's possible in theory.
If the cap file without the DEBUG component,the decompiling source(.java) files will lost many informations.
It will be difficult to read or understand.
