Exercise 7.2:Entity Relationships in CMP 2.0, Part 2
The example programs in Exercise 7.2 illustrate the remaining four types of entity-bean relationship:
Many-to-one unidirectional (Cruise-Ship)
One-to-many bidirectional (Cruise-Reservation)
Many-to-many bidirectional (Customer-Reservation)
Many-to-many unidirectional (Cabin-Reservation)
Start Up JBoss
If you already have JBoss running, there is no reason to restart it.
Initialize the Database
No database is initialization needed; JBoss will create the needed tables at bean deployment.
Build and Deploy the Example Programs
Perform the following steps:
Open a command prompt or shell terminal and change to the
ex07_2directory created by the extraction processSet the
JAVA_HOMEandJBOSS_HOMEenvironment variables to point to where your JDK and JBoss 4.0 are installed. Examples:Windows: C:\workbook\ex07_2> set JAVA_HOME=C:\jdk1.4.2 C:\workbook\ex07_2> set JBOSS_HOME=C:\jboss-4.0Unix: $ export JAVA_HOME=/usr/local/jdk1.4.2 $ export JBOSS_HOME=/usr/local/jboss-4.0Add ant to your execution path.
Windows: C:\workbook\ex07_2> set PATH=..\ant\bin;%PATH%Unix: $ export PATH=../ant/bin:$PATHPerform the build by typing
ant.
As in the last exercise, you will see titan.jar
rebuilt, copied to the JBoss deploy directory,

Examine and Run the Client Applications
This exercise uses six example programs to demonstrate ...
