Course Description
This training course teaches you how to create Web interfaces using JavaServer Pages technology. It covers the very latest technologies that are now available to the Java Web application developer, including the JSP Standard Tag Library, Struts, JavaServer Faces, Portlets and the JSP Expression Language as well as JSP architecture, working with JavaBeans, and how to interface with Enterprise JavaBeans and Web services. The training course can be delivered using a number of development tools, including IBM Rational Application Developer, Oracle JDeveloper, Eclipse, or a basic text editor.The training course can be delivered on most deployment environments, including Tomcat, WebSphere, Oracle AS, JBoss, and WebLogic.
Target Student
Web developers who need to be able to build enterprise Java based Web applications using JSP.
Prerequisites
- Delegates must be familiar with XML, and they must also be familiar with Web technologies such as HTML and HTTP. Java programming experience is desirable but not essential for this training course. If you do not have Java, then some scripting experience would be extremely advantageous.
Delivery Method: Instructor led, group-paced, classroom-delivery learning model with structured hands-on activities.
The training course combines lectures with practical exercises that help the delegates to put what they have learned on the training course into practice. The exercises specifically build on what has been recently taught and are built up as the training course progresses.
