I have downloaded and finished the new trial SCDJWS mock exam and I don't see any question about UDDI and JAXR. My question is, this topic is not or less covered in the real exam or questions are available in full question bank?
I certified in OCJWCD and SCBCD with support of Enthuware mock exams and I know it's a really good product.
Himai Minh is correct: UDDI and JAXR are not on the EE6 exam. The only thing you should know about them is what they do roughly as you might get a question with the JAXR or UDDI terms in it (but they won't ask anything about how it works)
