Hi,
I find this assessment test not very difficult. I have never used EJB, only web components. I don't have a clue what a home interface is used for.
I passed the test and needed only 20 minutes to answer the questions. I also passed the XML assessment test on the first attempt.
Cheers,
Roland (taking the real XML exam this Friday)

Well, I would still say, though that this ICE exam is a fair example of the examination, though I think it is easier than the real exam.
There is, somewhere, a site with the answers and explanations to the mock exam questions, if memory serves...

Theo,
Would you mind if I tell you correct my following statement. I am asking because I know the any one or two data in the statement is wrong.
IBM J2EE Connectivity Test is a 55 questions exam requiring 69% to pass and the allotted time is 120 minutes.

Actually, it's 'T.J.', but why quibble.
You can tell me anything - doesn't mean I'll do it. (Sorry, feeling obnoxious this morning.) In all seriousness, sure, I'll be happy to correct this, but I need to double-check when I get home.
What I do know is it's a 58 question exam. I seem to recall that it allows the examinee 90 minutes to answer all the questions and is looking for a 60% or better score, but I might be mis-remembering.

Try these answers.
Q1. Answer B, C, D are correct. As that question allows 1 answer only, the question itself is WRONG. The question should be
In deployment descriptors, WHICH OF THE FOLLOWING IS WRONG ABOUT security roles and method permissions:
and the answer is A.
Q11. The correct answers are A, B, D.
