Subject: zlib Deflate to java.util.zip inflate problem

Hello, I'm a total ruby newbie and am developing a simple app that  
tests an  existing web app. Part of the request I need to post  
contains data that needs to be compressed as the web app will  
uncompress it. Currently, the java app just uses simple  
java.util.zip.Inflater to do this, and I've been able to do this from  
cocoa to java no problem. Using Ruby to craft the data and post  
request has presented a problem: when the web app gets the request,  
I'm getting exceptions from java.utl.zip Unkown Compression format I  
can't change the back end, only the ruby client side. Does anybody  
know how to properly use the ruby zlib library to deflate data such  
that java's built in classes can inflate it? Sorry if this is a basic  
question; I've googled this to death and hit nothing but dead ends.  
Here's the call that compresses:

compressedBroadcast = Zlib::Deflate.new(nil, - 
Zlib::MAX_WBITS).deflate(binaryBroadcastData, Zlib::FINISH)

Other than this, I'm very much enjoying the other Ruby bits. Thanks  
for any pointers.
