Exercise 4.1: A Simple Entity Bean
The Cabin EJB demonstrates basic CMP 2.0 capability for a simple entity bean mapped to a single table. The following sections outline the steps necessary to build, deploy, and execute the Cabin EJB example. Please note that because you’re using JBoss’s default embedded database, you don’t need to configure the database or create tables. The code you’ll see here mirrors the example code provided in Chapter 4 of the EJB book.
Start Up JBoss
Start up JBoss as described in the JBoss Installation and Configuration chapter at the beginning of this workbook.
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

Open a command prompt or shell terminal and change to the
ex04_1directory created by the extraction process.Set the
JAVA_HOMEandJBOSS_HOMEenvironment variables to point to where your JDK and JBoss 4.0 are installed. Examples:Windows: C:\workbook\ex04_1> set JAVA_HOME=C:\jdk1.4.2 C:\workbook\ex04_1> set JBOSS_HOME=C:\jboss-4.0Unix: $ export JAVA_HOME=/usr/local/jdk1.4.2 $ export JBOSS_HOME=/usr/local/jboss-4.0Add
antto your execution path. Ant is the build utilityWindows: C:\workbook\ex04_1> set PATH=..\ant\bin;%PATH%Unix: $ export PATH=../ant/bin:$PATHPerform the build by typing
ant. Ant usesbuild.xmlto figure out what to compile ...
