Enterprise JavaBeans 3.0, 5th Edition

Chapter WORKBOOK 12. Exercises for Chapter 15

This chapter implements the interceptor examples shown in Chapter 15 of the EJB book.

Exercise 15.1: EJB Interceptors

This exercise implements the profiling interceptor shown in Chapter 15. The @javax.interceptor.Interceptors annotation is applied to the TravelAgent EJB’s bookPassage( ) method to show method-level interception.

Start Up JBoss

If you already have JBoss running, there is no reason to restart it. Otherwise, start it up as instructed in Chapter 15.

Initialize the Database

The database tables will be created when Exercise 15.1 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 ex15_1 directory created by the extraction process.

2. 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\ex15_1> set JAVA_HOME=C:\jdk1.5.0
   C:\workbook\ex15_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

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

   Windows:

   C:\workbook\ex15_1> set PATH=..\ant\bin;%PATH%

   Unix:

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

4. 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, and redeployed by the application ...
