Ummm... WSAD is of the IBM variety, not BEA, CV.
WSAD is an Integrated Development Environment and you can still use pretty much any container you want.
I'll move this over to a more appropriate forum so someone can help you work through getting your environment set up. I also recommend that you ask some of the colleagues you work with about how to set up a web project and run it on WAS or on Tomcat.
