Developing Java Web Applications:
Hands-On

What is this course about?

This course is about building enterprise Web applications using server-side Java. Java servlets and JavaServer Pages (JSP) allow developers to leverage the power of the Java EE 6 platform and create object-oriented, scalable, n-tier applications. Using Java servlets and JSP, developers can implement server-side logic for their Web-based applications, including creating a Web interface to a database. In the course, the participants integrate servlets and JSP for a complete Web solution.

Who will benefit from this course?

This course is useful for programmers, software engineers, analysts and managers involved in developing Web applications with server-side Java. Those who want to use Java applets in their Web pages should instead take Course 470: Developing a Website: Hands-On.

What background do I need?

You must have 3-6 months' Java experience and should:

• Understand Java classes and the inheritance model
• Be able to use the standard Java APIs

In addition, familiarity with intranet/Internet development technologies such as HTML, HTTP and TCP/IP is helpful. If you don't have Java experience, you can take Course 471: Java Programming: A Comprehensive Hands-On Introduction. For an introduction to intranet/Internet development, you can take Course 470: Developing a Website: Hands-On.

What version of Java does this course cover?

This course has been fully updated to Java EE 6.

What are Java servlets?

Java servlets are a powerful way of extending functionality of Java-enabled Web servers. They are commonly used to generate HTML documents on the fly.

What are JavaServer Pages (JSP)?

JavaServer Pages allows developers to easily create dynamic, interactive Web pages by embedding scripts directly into HTML. Using JSP, you can quickly create powerful intranet and Web applications that incorporate enterprise resources such as databases, networked servers and distributed objects.

What is JSF and how is it used in this course?

JSF, or JavaServer Faces, is a Sun standard for developing rich user interfaces to Web applications. The programming model is similar to Java Swing development, but for browser-based clients. By leveraging the JSF framework, the developer can quickly build a Web application by simply focusing on the business logic. In this course, we investigate installing and configuring the JSF framework.

What version of JSF is used in this course?

In this course, we use the current version of the JSF 2.0 technology.

What systems and software are used?

The normal classroom setup uses PCs running a Web browser, and a Web server hosting servlets and JSP. The course also uses a Windows platform running Oracle as a database server. However, everything you learn during this course applies to UNIX, Macintosh and other systems.

Which application server is used in this course?

You use the Apache Tomcat application server for the classroom exercises. However, the course notes and exercises adhere to Sun's servlet and JSP standards. The applications developed in the course are portable to all Java EE 6 application servers including WebLogic, WebSphere, iPlanet, Oracle JServer, JRun, JBoss, etc.

Does the course use Sun's development tools, the JDK or any IDEs?

This programming course uses Sun's Java Platform, Standard Edition (Java SE 6). The course also uses the Eclipse Java IDE. The concepts you learn in the course will also work in Borland JBuilder, IBM WebSphere Studio and other Java IDE tools.

How much time is devoted to each topic?

What is covered during the hands-on exercises?

Approximately 50 percent of this course is spent in hands-on exercises. During the exercises, you learn how to integrate servlets, and JSP technologies for a complete Web solution. You learn how to publish the contents of your database on the Web. The course also covers the techniques for keeping track of users by utilizing cookies and sessions. You learn how to build Web applications based on the JSF framework. A final exercise guides you through the steps for adding security to your Web site with Secure Sockets Layer (SSL).
