Utility Class for uploading and unpacking a zipfile?

[Günther Schmidt <gu...@kmmd.de>]

Hi,

I have discovered JcrUtils and it has come very handy.
There is one particular problem that gives me trouble, uploading an 
extracted zip file.

I'm using Jackrabbit to archive emails and all attachments come in as 
InputStreams with filename and mime type information.

Is there already a Utility for unpacking and uploading ZIPs in one go?
