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?

Section 9: Designing and Developing Reusable Web Components 9.1 Given a description of required functionality, identify the JSP directive or standard tag in the correct format with the correct attributes required to specify the inclusion of a Web component into the JSP page Section 10: Designing and Developing JSPs Using JavaBeans 10.1 For any of the following tag functions, match the correctly constructed tag, with attributes and values as appropriate, with the corresponding description of the tag's functionality: Declare the use of a JavaBean within the page. Specify, for jsp:useBean or jsp:getProperty tags, the name of an attribute. Specify, for a jsp:useBean tag, the class of the attribute. Specify, for a jsp:useBean tag, the scope of the attribute. Access or mutate a property from a declared JavaBean. Specify, for a jsp:getProperty tag, the property of the attribute. Specify, for a jsp:setProperty tag, the property of the attribute to mutate, and the new value. 10.2 Given JSP attribute scopes: request, session, application, identify the equivalent servlet code. 10.3 Identify techniques that access a declared JavaBean. Section 11: Designing and Developing JSPs Using Custom Tags 11.1 Identify properly formatted tag library declarations in the Web application deployment descriptor. 11.2 Identify properly formatted taglib directive in a JSP page. 11.3 Given a custom tag library, identify properly formatted custom tag usage in a JSP page.

Section 12: Designing and Developing A Custom Tab Library 12.1 Identify the tag library descriptor element names that declare the following: the name of the tag the class of the tag handler the type of content that the tag accepts any attributes of the tag 12.2 Identify the tag library descriptor element names that declare the following: the name of a tag attribute whether a tag attribute is required whether or not the attribute's value can be dynamically specified 12.3 Given a custom tag, identify the necessary value for the bodycontent TLD element for any of the following tag types: empty-tag custom tag that surrounds other JSP code custom tag that surrounds content that is used only by the tag handler 12.4 Given a tag event method (doStartTag, doAfterBody, and doEndTag), identify the correct description of the methods trigger.
12.5 Identify valid return values for the following methods: doStartTag doAfterBody doEndTag PageConext.getOut 12.6 Given a "BODY" or "PAGE" constant, identify a correct description of the constant's use in the following methods: doStartTag doAfterBody doEndTag 12.7 Identify the method in the custom tag handler that accesses: a given JSP implicit variable the JSP page's attributes 12.8 Identify methods that return an outer tag handler from within an inner tag handler. Section 13: 13.1 Given a scenario description with a list of issues, select the design pattern (Value Objects, MVC, Data Access Object or Business Delegate) that would best solve those issues. 13.2 Match design patterns with statements describing potential benefits that accrue from the use of the pattern, for any of the following patterns: Value Objects MVC Data Access Object Business Delegate
Since we already have the Servlets and JSP forum that takes care of many of these objectives, I think we should wait atleast until this certification becomes publicly available.

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)
Paul, I would like discussions to occur for IBM ICE in my forum located at IBM Application Servers, at least till a new forum for this is created which would be based on need. I think it is premature to create a Sun Certified Web Component Developer forum till it becomes official. We can however undertake discussions in our JSP and servlets forum for this temporarily. ------------------ Mahindrakar IBM Application Server Forum Moderator SCJP

Sun took some sort of random sample of people that passed the SCJP and SCJD exams world-wide, chose 250 of them, and then sent them emails inviting them to register to take this beta exam for free. No one else has pointed out though, that since it is a beta it will be way harder than the actual final exam that will eventually be released for public consumption. We have been told to expect the beta exam to have around 150 multiple choice questions and we will be given around 4 hours to complete it.
Forgive me as I am a new member to the JavaRanch, but how do you create a forum? In addition, with this certification being so new, are there any books available (or courses) for taking this exam?

You have to be all powerful to create a forum. In terms of JavaRanch that means that you have to be a sheriff. Of course no sheriff is going to do anything a drastic as create a new forum until Paul Wheaton gives the OK. As far as the new cerification, there are not books or classes that are directly intended to help you pass the exam yet because the certification doesn't exist yet. However the topics that the exam covers have been around a while and there are books and classes that cover those. Check out the BunkHouse for books on J2EE and such.

The Sun certification page has announced that the sun certified web component developer exam will be made publicly available as of July 31. I for one think would like to take it. I think it willbecome quite populare as most of the java developers that I know are more comfortable with servlets/jsp than the swing and file io topics that were tested on the SCJP exam. I think a new discussion would be a great idea as there is not alot of info on this exam out there. I'll post my ideas on the exam after I take it in the first week of Aug. Jeff Anderson
