Servlet & JSP Programming using WebSphere Studio Application Developer (WSAD)
Duration
Five days
Description
This workshop will teach students a variety of java and Servlet programming skills in a WSAD environment. The class begins with exploring WSAD and how it works with Java. The students then learn to use Servlets and JDBC. The course also covers JSP syntax, deployment and application models with some exploration of Java as a scripting language. The students will learn about the capabilities and architecture of Servlets. They will discuss the advantages of Servlets over CGI and how to deal with exception handling and session management.
Audience
This course is designed for programmers.
Pre-requisites
The student should have a working knowledge of Java programming and some experience with HTML.
