IDfSession treatment

jmeabe

Hi!

I'm deploying some java code for documentum, and I've a doubt. To get an IDfDocument, I previously get an IDfSession with the method getSession() defined in the class IDfTypedObject:

IDfSession session = getSession();

IDfDocument document = (IDfDocument)this.session.getObject(getObjectId());

My question is, do I need to release or disconnect the session? For the moment I'm not doing it, and in my jboss log file it appears many times an error that says that unreleased sessions during garbage collector are found, which gives me the suspicion that something is wrong with my sessions treatment... and if so, which method should I use to do it? I've been looking through the IDfSession class methods but no session releasement methods are defined...

Thanks in advance!

Yes - sessions should be released via IDfSessionManager.release(). You can get the session manager from the session.

The one thing to bear in mind is that some of the frameworks handle sessions automatically. For example, in WDK component a session is made available through component.getDfSession() but you don't have to release it as the underlying framework handles this.

There is no automated session management in Java server methods so, yes, you should release the session. Having said that most people tend to write an abstract server method class that contains logic for getting a session,invoking an abstract method (where your business logic would go) then releasing the session.
