JBPM 3.0 Documentation

[ramirini]

The 7.4 Chapter says that in order to get the database connection is necessary call to:
Connection connection = ctx.getProcessInstance().getJbpmSession().getSession().getConnection();

However the ProcessInstance object doesn't have the getJbpmSession method.

How I can retrieve the JbpmSession?

I am working with Jbpm 3.0

Thanks!

Try

JbpmSession jbpmSession = JbpmSession.getCurrentJbpmSession();

[ramirini]

It doesn't work with

JbpmSession jbpmSession = JbpmSession.getCurrentJbpmSession();

The jbpmSession is null.

I think that the JbpmSession Object should be retrieved from the ExecutionContext.

Thanks!

In order for JbpmSession.getCurrentJbpmSession() to return a valid session, the current thread should have opened a JbpmSession earlier via JbpmSessionFactory.openJbpmSession(). This is normally achieved by opening a session from the enclosing application, loading a token using that session and then signaling the token, so that the session is available for user-defined actions.

Why? What other ways are there to create JbpmSessions besides "new JbpmSession(JbpmSessionFactory, Session)" and "JbpmSessionFactory.openJbpmSession()"?

Or you mean that JbpmSession.getCurrentJbpmSession() will only return null if you never opened a JbpmSession (in the current thread, of course)?
