Thanks for letting know. No I am not having Ethuware mock exam, I have already been fooled by one mock exam provider called as "ezpractise" http://www.epractizelabs.com/
I hate them with passion. Since then, I have stopped following such exam softwares.
I think we should see oracle recommended training in such a case and follow the topics included in it; for this certification oracle recommends following courses:
Java EE 6: Develop Web Services with JAX-WS & JAX-RS: http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=609&get_params=dc:D77754GC10,p_preview:N
Developing Web Services Using Java Technology, Java EE 6: http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=609&p_org_id=1001&lang=US&get_params=dc:D65185GC10,p_preview:N
If you notice the topics for best practises in them you will find:
Trade-Offs Associated with the Java Web Services APIs
Understand the trade-offs involved in the choice to implement a web service using either JAX-WS or JAX-RS technology.
Web Services Design Patterns
Describe web services-based design patterns
Describe web services-based deployment patterns
Best Practices and Design Patterns for Use with JAX-WS
Describe JAX-WS-specific design patterns
Recognize and apply best practices associated with implementing web services using JAX-WS
Best Practices and Design Patterns for Use with JAX-RS
Describe JAX-RS-specific design patterns
Recognize and apply best practices associated with implementing web services using JAX-RS
Suppose we go for both of these course and pay 7000$ (highly unlikely - similar to finding life on moon) and after that we appear for exam and suppose we fail, then just imagine that the complaint process and nightmare you will give oracle.. it will be an embarssing situation for the tutor that the course was not suitable to qualify the exam, and that oracle provided false info on there site! so, i guess you realize where i am going with this, so the logic is if i am covering these topics then i may be safe.
Its better to cover more rather than less ground so to be on safe side. anyways, let me know if you feel i am mistaken, thanks.
btw, when are you planning to appear for the exam?
