The CX310-082 (Sun Certified Web Component Developer for the Java 2 Platform, Enterprise Edition 1.4 Upgrade Exam) test checks your ability to use the basic syntax and structure of the Servlet and JSP pages. This test requires you to have a good understanding of Java, Servlets, and JSP pages, and the ability to write code for well-defined design applications. For this purpose, along with studying books and taking various practice tests, you should also practice with Servlets and JSP code. This will let you learn a lot of things that are of great importance from the test point of view. The test asks all sorts of tricky questions that you might not consider in the real world. Practicing the following things with the subject will make you confident enough of scoring well in the test:

• Describe the purpose of the Servlet life cycle.


• Describe the event sequence of the Servlet life cycle.


• Write code using the HttpServletResponse interface.


• Construct the correct structure of the deployment descriptor.


• Describe the Web container request processing model. Describe the use of a filter and a wrapper and write code to configure them.


• Describe the life cycle of a listener. Create and configure scope attribute listener classes. Identify the proper use of attribute listener in a given scenario.


• Write code to add an object to a session using session listeners. Write code to respond to an event when a session object migrates from one VM to another.


• Describe session management mechanism and cookies to manage sessions. Describe URL rewriting that might be used to manage sessions. Write servlet code to perform URL rewriting.


• Declare the login configuration and a security constraint and a Web resource in the deployment descriptor.


• Write JSP code for the page (with attributes 'import', 'session', 'contentType', and 'isELIgnored'), include, and taglib derctives. Write XML based JSP documents.


• Configure the deployment descriptor for deactivating the evaluation language and for deactivating the scripting language.


• Write EL code to access the following in your code : implicit variables, property access (the . operator), collection access (the [] operator), arithmetic operators, relational operators, logical operators, and EL function.


• Write code snippets using the following standard actions: jsp:include, jsp:forward, and jsp:param.


• Use an appropriate JSP Standard Tag Library (JSTL v1.1) tag from the core tag library.


• Write tag handler code to access the parent tag and an arbitrary tag ancestor. Describe the semantics of the simple custom tag event model.


• Study the following list of patterns: Intercepting Filter, Model-View-Controller, Front Controller, Service Locator, Business Delegate, and Transfer Object.


• Match design patterns with statements describing potential benefits that accrue from the use of the various J2EE patterns.
