Get JackrabbitSession with Jackrabbit-JCA on Glassfish

[Stefan Hagedorn <na...@gmx.de>]

Hi,

I am running my application that uses the Jackrabbit repository on a 
Glassfish v3 application server. I am using jackrabbit-jca 2.1.0

In order to use jackrabbit ACLs I am doing

Session s = repo.login(...);
UserManager umngr = ((JackrabbitSession) s).getUserManager();

But this cast is not possible and throws an exception:

java.lang.ClassCastException: org.apache.jackrabbit.jca.JCASessionHandle 
cannot be cast to org.apache.jackrabbit.api.JackrabbitSession


So, could anyone please tell me how to receive an JackrabbitSession 
object (or any other way to get the user manager)?

Regards,
Stefan

Looks like JCA is putting a wrapper around the session, if JCASessionHandle does not have an exposed method to get the JackrabbitSession or the class definition that was used to create the JackrabbitSession is not available to the classloader you are working in then you might be able to do it with reflection. (IIRC Glassfish v3 is OSGi based, is JackrabbitSession exported from its bundle ?)

In Apache Sling (also OSGi based), AccessControlUtils in the server bundle does just this, although there isn't the added complexity of JCA.
