I was messing around with CounterPath's Eyebeam client to try and get it to register against an XCAP Servlet I'm hacking up using the org.openxdm libraries.
The servlet was hosted on port 7001 (BEA's Weblogic).
I'd tetherealed the output and noticed that while my command line tests with CURL were working a treat, eyebeam was sending nothing at the friggin XCAPServlet. I found a few posts on the mobicents lists about this issue but no response. Well, for some reason the great folks at counterpath decided that the Mac OSX implementation of Eyebeam should use the web proxy be default. The proxy was duly 404'ing my localhost test. DOH!
The software works but I didn't half feel like a complete muppet :)
Sometimes I wish that programmers would think hard before they introduced any kind of intelligence into a software application.
