[JDEV] request for help (jabber protocol - xml streams)

[zak]

hi all,

i'm just starting out and was just trying to write a really simple test to 
connect to a jabber server.  however, for some reason my parser hangs when 
trying to read the first <stream:stream response from the server.  here is 
the code for reference.  i know it's really bad code, but like i said, i was 
trying to do something fast and simple as an example.  not sure if i'm making 
some protocol errors or if i'm hanging because something is blocking?  any 
ideas?

thanks, zak.
