Hello David,
I have followed your instructions and it worked great. Unfortunately, I
haven't been able to find a way to expose jackrabbit as a JNDI resource.
This was possible in JBoss by defining a *-ds file like the following:
<connection-factories>
<tx-connection-factory>
<jndi-name>jcr/local</jndi-name>
<xa-transaction/>
<rar-name>etask-jackrabbit-jca.rar</rar-name>
<connection-definition>javax.jcr.Repository</connection-definition>
<config-property name="homeDir"
type="java.lang.String">C:/path/to/repository</config-property>
<config-property name="configFile"
type="java.lang.String">classpath:repository.xml</config-property>
<config-property name="bindSessionToTransaction"
type="java.lang.Boolean">true</config-property>
</tx-connection-factory>
</connection-factories>
I didn't find any documentation as to the way to deploy such a resource (the
repository). Do you know of any site where I can find this?
Regards,
Camilo.

Once the Resource Adapter is deployed you should be able to use any of
these techniques to get a reference to any object that the Resource
Adapter can create.
http://openejb.apache.org/3.0/resource-ref-for-datasource.html
This doc shows DataSource, but the @Resource annotation can be used to
get references of Resource Adapter created objects put into JNDI for
lookup and optionally for injection.
Hope that was the answer you were looking for. Let me know if that
doesn't do the trick.
