Re: Get imported packages using BCEL

Imports are basically a form of stating dependencies.

If you are after the dependencies - sure, they can be extracted from  
the class. So does e.g. minijar

  http://vafer.org/blog/tag/minijar

It uses ASM - not BCEL ...but that's just an implementation detail.

Maybe tell us a bit more what you are trying to do

cheers
