Java EE 6 Web Services Developer Certified Expert Exam - Study Help

[Navin KumarD]

Can someone provide Detailed objectives for J2EE 6 version of web-services exam. I need to know the versions of SOAP, WSDL and BP.
Do we have UDDI and JAXR topics as part of this exam?

I am reading Richard Monson-Haefel Book for this exam do i need to read topics other than XML, SOAP, WSDL and JAXP from this book?

Please reply ..

[Rajeish Mittal]

I assume UDDI and JAXR topics are not part of the topics as per the response received. A little bit exploring the forum will take you long way to get info required.

I am beginning to study for this exam, and am finding it difficult to understand what is relevant and what is not. I'm hoping to bypass as much outdated material, as possible. I will try to update this post, as I discover more. So far this is what I found..

Language:Version:reference site
SOAP:1.1:http://www.w3.org/TR/2000/NOTE-SOAP-20000508/
WSDL:1.1:http://www.w3.org/TR/wsdl
JAX-WS:not sure:http://jax-ws.java.net/nonav/2.2.7/docs/index.html. Includes: JAXB & SAAJ

Not relevant
JAX-RPC:deprecated by JAX-WS - reflects move away from RPC-style to document-style WSs.

If anyone can provide me with more insight, it would be greatly appreciated.

I have also just started preparing for JWS 6, and believe RMH book ch. 22, 23, 24 would be helpful to build a base for these topics.
Once we have some understanding of these topics, then one can google for specific topics & issues or discuss here.
