WA1321 Servlets & JSP Development with Rational Application Developer (RAD) v6 Training and Courseware

Quick Enroll

Students will learn to develop and test server-side applications based on the Java 2 platform, Enterprise Edition (J2EE) component model using the IBM software platform of products and tools. Develop and test server-side applications that use servlets and JavaServer Pages (JSPs) for the control and flow of e-business applications.

Topics
	Develop and test servlets Develop and test JavaServer Pages (JSPs) Develop and test J2EE applications following the Model/View/Controller architecture Integrate business logic using Java Beans and Java Database Connectivity (JDBC) Apply best practices to servlet and JSP development

Practical Work
	Students will have the opportunity to build a simple Java program, servlets and JSPs using RAD v6. Students will also deploy a J2EE application into WebSphere Application Server v6.

What you will learn
	After completing this course, the student should be able to: Use RAD v6 as a truly integrated development environment Build servlets according to the current Servlet 2.4 specification Build JSPs according to the current JSP 2.0 specification Build custom JSP tag libraries Integrate servlets and JSPs into a complete J2EE application Test servlets and JSPs using the WebSphere Test Environment Deploy a J2EE application to WebSphere Application Server

Audience
	Java programmers who build server-side web applications interested in leveraging RAD v6 to streamline their development cycle.

Prerequisites
	You should understand essential concepts of Object-Oriented Programming and be able to write simple Java programs with assistance

Duration
	Five days
