You re on the right way Roger...
Now you have to tell jBoss that he shall bind Hypersonic (pr whatever to
your sessions environment under the specified name. You do this in
jboss.xml.
My version of EJX doesnt support that dont know if wether I missed
something or it isnt implemented yet...
Anyway
You must create a resource-manager (this works with EJX):
<resource-managers>
...
<resource-manager>
<res-name>your_resource</res-name>
<res-jndi-name>Hypersonic</res-jndi-name>
</resource-manager>
</resource-managers>
the <res-name> is the logical name you give your resource
the <res-jndi-name> is the jndi name of your real DataSource you want to
use (eg: Hypersonic)
in the enterprise-beans section you have to specify the resource-ref
then:
<enterprise-beans>
<session>
...
<resource-ref>
<res-ref-name>jdbc/database</res-ref-name>
<resource-name>your_resource</resource-name>
</resource-ref>
</session>
...
</enterprise-beans>
<res-ref-name> is the same <res-ref-name> as in the <resource-ref>
section in your ejb-jar.xml file.
<resource-name> is the logical name you gave the resource manager in the
resource-manager section.
