in your opinion, should we wait till EE 5 finalized? Does the exam cover EJB as well? How useful this certification compare to ones from IBM for example?
The book covers, in two additional chapters, all the changes to the
Java EE 5 Web tier, with the exception of JavaServer Faces which is just too big to put at the end of one book! My contact at Sun almost guaranteed me the SCWCD exam wouldn't be updated - aside from the addition of
JSF, there isn't anything fundamentally different.
The SCWCD exam does not cover EJBs - the SCBCD exam will be revised significantly for Java EE 5.
As for IBM certifications, I was under the impression that their certs. are all based around their products like Websphere and the Rational line. I've had a quick search around their cert. site and couldn't find any references to J2EE outside these contexts - I could be wrong however? I think in this instance it's wise to take the certification from the source, and the Sun SCWCD 1.4 objectives are rigorous!
