Need a tool to compare two .ear files recursively

Question

I'm modifying a build process and I need to do a complete comparison of the contents of two .ear files. That means recursively comparing each archive in the .ear. These .ear files have archives that contain archives.

I've looked at Beyond Compare and Archive Analyzer, but they only do one level at a time. I have to manually drill down into each archive. I'm looking for something more automatic.

Eclipse and UltraCompare do a binary comparison of the two .ears which is not what I want.

Does such a tool exist?

zipdiff provides a very good open source solution.
