Servlets and JavaServer Pages (JSP)
Duration:   Three days
Audience Prerequisites

This course is designed for developers who already have some experience in Java.

  • Architects
  • Designers
  • Consultants
  • Developers

Description
Java Servlet technology provides a Java-based replacement for CGI scripts. It offers better performance, portability among different platforms, and full access to the Java technology. It also enables enterprise developers to build server-side components that generate and serve web pages dynamically. JSP is based on Servlets. It enables web designers to embed Java code in HTML pages through easy-to-use tags. Using JSP, developers can access other Java applications and business objects to build dynamic Web pages.

This is a highly hands-on course. At least 50% of the time will be spent on labs. This course may be delivered using WSAD 5.x, Rational Application Developer 6.x, WebSphere 5.x/6.x, Tomcat, or WebLogic 8.x. Please contact us if it is needed on other platforms.
