Exercise 7.1: Entity Relationships in CMP 2.0, Part 1
This exercise walks you through implementing a complex set of interrelated entity beans defined in Chapter 7 of the EJB book.
Start Up JBoss
If JBoss is not running, start it up. If it’s already running, there’s no reason to restart it.
Initialize the Database
The database table for this exercise will automatically be created in JBoss’s default database, HypersonicSQL, when the EJB JAR is deployed.
Build and Deploy the Example Programs
Perform the following steps:
Open a command prompt or shell terminal and change to the
ex07_1directory created by the extraction process
JBOSS_HOMEenvironment variables to point to where your JDK and JBoss 4.0 are installed. Examples:
C:\workbook\ex07_1> set JAVA_HOME=C:\jdk1.4.2 C:\workbook\ex07_1> set JBOSS_HOME=C:\jboss-4.0
$ export JAVA_HOME=/usr/local/jdk1.4.2 $ export JBOSS_HOME=/usr/local/jboss-4.0
antto your execution path.
C:\workbook\ex07_1> set PATH=..\ant\bin;%PATH%
$ export PATH=../ant/bin:$PATH
Perform the build by typing
As in the last exercise, you will see
rebuilt, copied to the JBoss
and redeployed by the application server.
Examine the JBoss-Specific Files
This chapter introduces no new features in JBoss-specific files. Please review Exercise 6.1 to understand the JBoss-specific files in this example. Also, this chapter implements nonperformance-tuned entity beans and ...
