I am planning to write SCJDWS exam. I just want to know how long the exam is valid. Is SUN about to release new version / syllabus for web services exam. I heard that JAX-RPC is the older model, now everybody using JAX-WS, even my company is using the same. SO I just want to know is there any changes going to happen in the syllabus. If not I am planning to prepare for this exam, so pls advise me.
