Congratulation on your pass.
Unfortunately, I took the beta exam in June and I failed.
Such is life. Well at least we have a forum now and with
the great notes provided, I hope to pass when I retake.
Thanks. I was hoping that I would get my results today as the exam went live today and therefore Sun would need to determine the pass mark.
Has anyone taken the exam and had theirs results yet?
It seems that Sun are now providing trial SCWCD exams (for payment ) from their website.
To my knowledge there is no site which can offer additional information as it has not been publicly released. I believe that it will become publicly available in August.
I just thought it would be nice to have a dedicated forum so that
I can share revision tips with other prospective candidates as there seems to be an awful lot to learn. (Basically a group of people sharing knowledge and resources similiar to the J2EE_SCEA discussion on egroups).
The Servlets and JSP forum seems to concentrate on real-world issues and not on exam questions, and I would be inclinded to believe that it should stay that way. Perhaps a new forum which discusses other exams in general ? (i.e. not only SCWCD but also IBM ICE and Oracle JDeveloper)

Out of interest, is there going to be a new forum for the Sun Certified Web Component Developer exam? (Similiar to the SCJP, SCJD and SCEA forums)
If yes, when can we have it?
18 years ago
Thank you very much indeed.

There was a seminar held about it within the states.
Unfortunately, I have not been able to find any other information on www.javasoft.com.

I believe so. However to achieve SCEA status can take a consider amount of time. It would be great if there was another exam which covered the web basics though....
Yes, it is definently from Sun.
This is now being discussed in the JSP and Servlets forum.
As I have already passed my SCJP and my SJCD, I have been asked if I would like to participate in this beta examination. Please note that this is invitation only, so if you have not received an email from the relevant sources, you are unable to participate.
Unfortunately, I have no other information. So I can't even tell you if this will become an actual exam or it is just an idea which will be put on the back burner for a while.
For the moment, my recommendation is to take the SCJP and the SCJD and then consider whether it is waiting for this exam (if it ever appears) or take the SCEA (for which I am currently revising).

Does anyone have any details about this emerging certification?
Sun Certified Web Component Developer Java 2 Platform, Enterprise Edition Technology.
This certification will cover JSP and Servlet technology. This exam is ideal for Developers who are Sun Certified in Java Programming and Developing.
