6.1.2. Building the Example

The simplest way to compile this and all examples is to go to the
directory and enter the following command line as user
ant -find build.xml install
This command compiles all examples in the
6.1.3. Configuring Database Access
In order to run this example, you must be able to access a relational database. Typically you would
use PostgreSQL, as it is preconfigured with Red Hat Application Server. JOnAS will create and use
a DataSource object that must be configured for the database you intend to use. These DataSource
objects are configured via properties files and are referenced in the
Section 4.1.2 JOnAS Configuration Files).
The file for your database needs to be in a location where your JRE can find it. (For example, if
jar
you are using PostgreSQL—Red Hat Edition and the IBM JRE, the following is necessary:
$ su
# cd /usr/lib/jvm/java-java_version-ibm-IBM_java_version/jre/lib/ext
# ln -s /usr/share/java/rh-postgresql3.jar .
6.1.3.1. Defining a Datasource
This example requires that a datasource named

6.1.3.2. Creating the Database
JOnAS does not automatically create the database for you—you have to create it prior to running this
example. The
