Thank you for the quick history review. BTW, the reason I am asking is because I would like to work on web services and in particular for JBoss. I was just trying to select a path that will be useful in the long-term. I've been looking at relevant JBoss code (the SPI and JBossWS-Native and also started looking at CXF and the JBossWS-CXF integration layer). I think I'll focus on CXF code for now.
