hello,
SCDJWS has just been updated (CX-310-230), so there will not be another update soon. SCBCD 5 (CX-310-091) is the latest version, and it refers to EJB 3.0 and JPA 1.0.
My impression is that the skills required to pass SCDJWS are in higher demand. Many of the topics refer to standards that are not specific to Java EE, like
SOAP and WSDL. The basis for this assessment are bid requests for freelancers in Germany.
As a very recent development, there seems to be good study material for the latest SCDJWS now. The problem is that there are not enough mock questions around - that I know of. This seems to be the best study guide:

For SCBCD 5 there are preparation kits. I recommend the one from Enthuware.
Personally I just don't dare to go for SCDJWS without mock questions. They are an essential part of my preparation. SCDJWS and SCMAD are the only Sun Java certificates I don't have.
