Java™ Servlet and JSP™ Programming

This intensive, hands-on course provides an introduction to Web application development using Java Servlets and Java Server Pages (JSP). Students will learn how to create powerful server-side programs that benefit from the Java enterprise environment.

A sound knowledge of Java is essential. Those unfamiliar with Java should take an introductory Java course first, such as Java 2 Programming Language. Some knowledge of HTML would be beneficial.

On completion of this course, the student should be able to

• Design a multi-tier Java Web application
• Develop Java Servlet Web applications
• Design forms to post requests to Java based Web applications
• Implement Web applications with JSP technology

Java programmers or architects who plan to develop distributed, multi-tier Java Web applications. This course is particularly targeted to those developers writing Web server applications that utilize Java enterprise technologies.

3 Days
