Enterprise JavaBeans 3.0, 5th Edition

Chapter WORKBOOK 9. Exercises for Chapter 11

This chapter implements exercises that illustrate the concepts introduced in Chapter 11 of the EJB book.

Exercise 11.1: Stateless Session Bean

This exercise utilizes the ProcessPayment EJB described in Chapter 11 of the EJB book. The code for this stateless bean is copied as is from Chapter 11, but a few additional classes are implemented to facilitate the example.

Start Up JBoss

If you already have JBoss running, there is no reason to restart it. Otherwise, start it up as instructed in Workbook 1.

Initialize the Database

The database tables will be created when Exercise 11.1 is deployed to JBoss. If you have problems running this example, shut down JBoss and run the clean.db Ant task.

Build and Deploy the Example Programs

Perform the following steps:

1. Open a command prompt or shell terminal and change to the ex11_1 directory created by the extraction process.

   Set the JAVA_HOME and JBOSS_HOME environment variables to point to where your JDK and JBoss 4.0 are installed. Examples:

   Windows:

   C:\workbook\ex11_1> set JAVA_HOME=C:\jdk1.5.0
   C:\workbook\ex11_1> set JBOSS_HOME=C:\jboss-4.0.x

   Unix:

   $ export JAVA_HOME=/usr/local/jdk1.5.0
   $ export JBOSS_HOME=/usr/local/jboss-4.0

2. Add ant to your execution path. Ant is the build utility.

   Windows:

   C:\workbook\ex11_1> set PATH=..\ant\bin;%PATH%

   Unix:

   $ export PATH=../ant/bin:$PATH

3. Perform the build by typing ant.

As in the exercises in earlier chapters of this workbook, titan.jar is rebuilt, copied to the JBoss deploy directory, ...
