This very short exercise demonstrates the use of the automatic cascade-delete feature of CMP 2.0 containers. It does this with an example Customer bean and some other beans related to it.
Perform the following steps:
Open a command prompt or shell terminal and change to the
ex07_3
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:workbookex07_3> set JAVA_HOME=C:jdk1.4.2 C:workbookex07_3> set JBOSS_HOME=C:jboss-
|
Unix:$ export JAVA_HOME=/usr/local/jdk1.4.2 $ export JBOSS_HOME=/usr/local/jboss-4.0
|
Add ant
to your execution path.
Windows:C:workbookex07_3> set PATH=..antin;%PATH%
|
Unix:$ export PATH=../ant/bin:$PATH
|
Perform the build by typing ant
.
As in the last exercise, you will see titan.jar
rebuilt, copied to the JBoss deploy
directory,
and redeployed by the application server.
There are no new JBoss configuration files or components in this exercise.
Client_73
is a simple example to
demonstrate cascade-delete. The example code is pretty
straightforward and needs no explanation.
In order to run Client_73,
invoke the Ant task
run.client_73
. Remember to set your
JBOSS_HOME
and PATH
environment
variables. The output should look something like this:
C:workbookex07_3>ant run.client_73 Buildfile: build.xml prepare: compile: run.client_73: [java] Creating Customer 10078, Addresses, Credit Card, Phones [java] Creating CreditCard [java] customer.getCreditCard( ).getName( )=Ringo Star [java] Creating Address [java] Address Info: 780 Main Street Beverly Hills, CA 90210 [java] Creating Phones [java] Adding a new type 1 phone number..
