jBPM and @Unwrap question

[bsmithjj]

Hello,

I am trying to come up with a pattern for initializing the Seam Actor for jBPM in my system. There is no login action in my system - we're authenticating using a custom Tomcat Valve (integration with an enterprise SSO system). So I tried to use the @Unwrap approach here:

@Name("initjBPMActor")
public class InitjBPMActor {

 @Logger Log log;

 @In
 private Principal userPrincipal;

 @Unwrap
 public Actor getActor() {
 // get an instance of Actor, set it's id using the userPrincipal.name value
 Actor actor = Actor.instance();
 actor.setId(userPrincipal.getName());
 log.info("getActor() : Actor -> "+actor);
 // todo - remove logging...
 return actor;
 }
}

I have a SFSB in which the Actor is @In'jected. When I invoke a method that uses the actor, it doesn't seem that getActor() is ever called (I don't see the log.info() message in my logging output). Furthermore, I think that this attempt to @Unwrap the Actor is causing problems with Seam, because once I attempt to invoke a method in my SFSB which does nothing but log.info()'s, I do not see output of the log.info()'s and the test case appears to fail (SeamTest).

If it's not possible to use Actor with @Unwrap (because it gets special handling by Seam), then is it possible to specify that the Actor ALWAYS gets its id from userPrincipal.name? (i.e. - some kind of default strategy - maybe it's a good idea to provide a few different strategies in the framework to pick from, including a custom strategy).

Thanks,

Oops - @Name("initjBPMActor") should be @Name("actor") - but that still doesn't work.

Just subclass Actor like this:

@Name("actor")
public class AutoActor extends Actor
{
 public String getId() { return UserPrincipal.instance().getName(); }
 ...
}

Or maybe:

@Name("actor")
public class AutoActor extends Actor
{

 @Create
 public void init() { setId( UserPrincipal.instance().getName() ); }
 ...
}

This worked!

Thanks!
