On a post in Javaranch.com, Valentin Crettaz commented that SCBCD is likely to be updated for EJB 3.0 and the new exam will be available by early next year (ie 2007). Of late, many have posted on Javaranch on whether its wise to take the present SCBCD exam (viz aligned to J2EE 1.3 version of EJB Spec 2.0) or wait for the upgrade when the exam aligns with Java EE 5.0 version of EJB Spec 3.0. Now the same question is being asked about the present SCDJWS 1.4 exam (aligned to J2EE 1.4 version of WS specs). Sun has made some major architectural changes to the erstwhile JAX-RPC 1.1 (so much so that the new stack is called JAX-WS 2.0) and also the other standards have evolved in the due course (like SOAP 1.1 obsoleted bySOAP 1.2, WSDL 1.1 obsoleted by WSDL 2.0 etc). But experts at Javaranch feel that an upgrade to the present SCDJWS 1.4 will take some time (it may even be upgraded by Java EE 6.0).
In my opinion, those planning to take SCBCD 1.3 may want to wait for the newer version of the exam as its just around the cornor now. For those who planned to take SCDJWS 1.4, they need to take it now and upgrade whenever the later version becomes available. From my experience, the person taking this exam will definitely benefit from his learnings of even an older version of Spec as the newer specs in general have evolved in a backward compatible manner.
The architecture and design of webservices application has remained unaffected. And even the most hit aspect of the exam, JAX-RPC (viz is about 30% of exam) continues to be used in the industry today.
Also, there will be alot of work aimed towards upgrading the older EJB 2.0/2.1 app to EJB 3.0 and a JAX-RPC 1.1 client/service to JAX-WS 2.0. And to do such a work, one will require not only the knowledge of EJB 3.0 or JAX-WS 2.0 but also of the earlier version viz the source of upgrade.
