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.
Yes, I saw it on the Java One Developer Conference brochure. They are having a Weekend session there on the new certification. I will quote it here. "Java 2 Platform, Enterprise Edition (J2EE) vendor's represent nearly 90 percent of the application server market. With the vast number of developers in the workforce, your success depends upon your ability to demonstrate your expertise with Java Servlets technology (JSP pages), JavaBeans technology-based components (JavaBeans components) and Enterprise JavaBeans (EJB) technology-based components (EJB Components). This full day session developed and taught by the lead member of the exam development team, provides a code-level, detailed review of the skills and knowledge necessay to pass Sun's soon-to-be-released certification exam for Web component developers. The session focuses on developing and deploying Web applications using Java Servlets technology, JSP pages, JavaBeans components and EJB components. This course discusses each of those technologies seperately, in addition to how they are best used together. At the conclusion of the session, you will receive a complimentary exam voucher ($150), that can be used to take the exam." There you have it Mark
Yes, they are in the beta test for this exam. Some SCJPs (including me) have been invited to participate this beta. The beta phase will be in may / june but I don't know when this will be internally finalised and promoted. Probably I am allowed to tell you more after the cert... Rainer

Sun sends out the Objectives in StarOffice's sdw format, and it took me hours to download the whole StarOffice.
Hi all Thanks a lot for this post and discussion. I am now a SCJD and have been invited to appear for the Beta Exam for free. I was also in a difficult position to get the objectives as I don't have star office. I tried mailing to Troia but he/she didn't reply.(nothing unusal) I found sun customer service very slow. I just let me see javaranch and oh boy did i get the clue..I got the whole objective here.Thanks a lot all of you especially Yang..Cheers all the best.
Hi all , Can somebody tell me how to register for this exam? Where can i find the details? Thanks, Manjunath B.S

Manjunath this exam is not yet open to all. Only 250 scjp and scjd's have been invited to do the beta exam free from 15th may till 9th june. After this the exam will be open. So wait until it is open Hope this helps.
Hi all, I am an SCJP and I wanted to know whether this new examintaion requires one to be an SCJD as well.Also when approximately will the exam be open to everyone. Since SUN is still conducting the beta test , I guess it would take some time for them to actually make this available to everybody.I am planning to get my SCJD certification but after having read this post I was thinking if I could wait and just give this one exam. Please advice. Thanks, Pooja

It sounds that Sun won't release SCWCD till several months later. If you didn't get the BETA exam invitation, it's better to get SCJD first. Yang-Chi Jeng
Any Ideas on the cost of this exam. I really cannot wait to give this one, it is really going to interesting. Is Javaranch going to open a new posting area for SCWCD ??? Thanx Vivek Viswanathan SCJP SCJD
Hi Yang, I would be grateful if you could please provide the link to the .sdw file containing the objectives for SCWCD, or send it to me by email. I have StarOffice 5.1 on CD, got it when I had attended a Sun Technology Day in Mumbai, India. Thanks in advance Prasanna SCJP2 email@example.com PS: I think at present, the only official link available about this exam is this: http://www.sun.com/java-university/javaone_2001/sessions.html#c2 What a session it must have been for those who actually attended it! For example, have a look at this:
Prepare for the Sun Web Component Developer Certification Exam Increase your understanding of Java technology Web applications Understand how Java Servlets and JSP pages are best used together Gain insights into developing extensible Web applications Learn how EJB components are used with Java Servlets and JSP components Explore Web application architectures Examine Web components Learn the rationale for the certification test Receive multiple code examples and sample test questions
WOW!!! I wonder if Sun is going to conduct similar sessions in India... [This message has been edited by Prasanna Wamanacharya (edited June 11, 2001).]
i took the exam on 09 june. overall, it was not as difficult as SCJP. There seemed to be a disproportionate number of questions on jsp tags (not a strong area for me) so bone up on custom tags and how to configure them in the deployment descriptor. the servlet and jsp parts i found easiest. i spent the majority of my preparation on these aspects of the exam. some really good sources to prepare are the actual servlet and jsp specifications from sun and sun's j2ee "blueprints". also a tip: when they ask you to give "the name of the tag..." do just that and do not type in the tag as it would go in the descriptor. for instance, the name of the tag that defines a servlet definition in web.xml is "servlet" and not "". i think i gave a couple answers like that which probably cost me a few points.
Sun is previewing a next version of the J2EE specification. Will it make the upcoming SCWCD obsolete by 2002 ? or will the next version simply enhance internal technology for speed and add a few more API's therefore not changing the test objectives ? Just wondering ...
sun is offering this from 31 july , as far as i know can i take the beta test is a beta test offered everywhere on-line i live in lhr , pakistan is there is no java one here so can i still take the beta tests can any body please guide me
