I only had 64%.
regarding webservices it is suggested to read tutorials from xyzws.com It covers so much of details, but you only have to get an overview of the webservices technology.
I feel you can read MZ guide to SCEA fot security objectives.

It was a difficult test for me.
questions were from all the Java EE technologies.
design pattern questions were revloved around only two or three patterns out of 44 patterns from GoF patterns and core J2EE patterns books.
a lot of questions from JSF, i was not very much familiar with JSF.
You are tested on a broad area and some times tested for indepth knowledge in a partcular area.
I have done Java EE Tutorial.
read Head first design Pattterns.
GoF book ( Core J2EE book was not available to buy)
MZ notes and EJB 3.0 spec and a lot of related material on the web.

Dear All,
I cant understand what is expected under following objective in SCEA5

�Explain how you would design a Java EE application to repeatedly measure critical non-functional requirements and outline a standard process with specific strategies to refactor that application to improve on the results of the measurements.

Hi
can any one explain the difference between three-tier and multi-tier ?
also better if you can

Explain the advantages and disadvantages when each of them examined under the following topics: scalability, maintainability, reliability, availability, extensibility, performance, manageability, and security (flexibility)
