I am working on an XMPP (www.xmpp.org) library that supports data compression.  I am specifically using Zlib compression.  However, when I use the Zlibstream to compress the byte array and send it to the XMPP server (OpenFire) I get nothing back.  I checked the log of the server and I see this:

java.io.IOException: Unknown error. Error code : 1

That seems to tell me that the data can't be inflated and I am not sure why not.  As I mentioned, I have a byte array that I am compressing.  The byte array was a string that I converted using GetBytes.  The data I am sending must be a byte array, which it is.  I initially created this as an issue but it might be more appropriate here.
