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.
