Hey Mike,
I've just passed the SCWCD exam myself. I'm kind of torn between SCBCD and Sun's
Java Web Services exam... I've already got the Head First EJB, so that's what I'm starting out on...
However, there is talk out there that EJBs are history. You can do a lot of similar things with Hibernate or Spring. (I can hear it now.. "EJBs?? They're so 2002!")
I've been told in a Java User Group to not even start with
Struts, but go direct to Spring.
Sorry for the non-answer, but I can begin to learn EJBs and get far enough along to (hopefully) pass the SCBCD exam, then I can use that as a further platform for other certs. Nobody ever fired someone because they knew EJBs.
