Java Servlet Programming

Revision: TE2404_20060318

Course Length:

2 Days

Course Description:

Prior to Java servlets, dynamic content from your Web server was accomplished by CGI and proprietary APIs. This course details a third way - the Java Servlet Development Kit (JSDK). The JSDK lets you extend a Java-enabled Web server with servlets, server-side components written in Java. These components are platform and protocol independent. Servlets can be used to replace CGI, process forms, interact with the database or as a middle tier in a three-tiered architecture.

Who Should Attend:

This course is designed for CGI programmers, JavaScript programmers, Java Applet programmers and authors of Web pages.

Benefits of Attendance:

Upon completion of this course, students will be able to:

• Understand how and when a servlet is loaded, and how and when it is executed.
• Understand how threads are managed and how to handle the synchronization issues in a multi-threaded system.
• Understand how a servlet can generate HTML, return errors, redirect requests, and write data to the server log.
• How to maintain security with servlets.
• Have servlets communicate with one another.
• Understand which charsets servlets may use to generate content in several languages.

Prerequisites:

Experience with Java programming is required.
