Exercise 6.1: Basic Persistence in CMP 2.0
This exercise begins walking you through the intricacies of CMP 2.0. In this chapter, you will learn more detailed JBoss CMP 2.0 configuration mechanisms by creating the Customer EJB described in the EJB book.
Start Up JBoss
If you already have JBoss running, there is no reason to restart it. Otherwise, start it up as instructed in the JBoss Installation and Configuration chapter.
Initialize the Database
The database table for this exercise will automatically be created in JBossâs 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
ex06_1directory created by the extraction process
JBOSS_HOMEenvironment variables to point to where your JDK and JBoss 4.0 are installed. Examples:
C:\workbook\ex06_1> set JAVA_HOME=C:\jdk1.4.2 C:\workbook\ex06_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\ex06_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.
