Guilty as charged, Mark
My company actually doesn't use Java, but is undergoing a major software system overhaul to make it more object-oriented. When this initiative was anncounced late last year, I volunteered to study Java as a possible alternative to VB/ASP (our current system), .Net (vaporware), and Python.
So I hit the books on Java, J2EE, OOAD, and do a bit of OO design here, a bit of prototyping in Java there, but I don't have the benefit of working with more experienced Java developers. This is why I enjoy coming to sites like JavaRanch, where Java experts share real-life solutions.
