Retrieving username from JBoss for db call setting application_context in Oracle [message #642035]

Hello,

I'm implementing VPD using an Oracle application_context.
For initializing it, I want to pass the username to oracle.

For this to happen, I have implemented a SessionEventListener which does the calls to the database.
Now my only problem is retrieving the username reliably.

If I retrieve the EJBContext via JNDI (all my db calls come from EJBs), then I sometimes get NullPointerExceptions stating, that the EJBContext is not available.

Are there more reliable ways?
How do you retrieve the username which is logged in ?

With kind regards

Where does your username come from?

You could try setting it in a thread local, or setting it as a EntityManager or EclipseLink Session property so it is accessible to the event.

Odd that the app server EJBContext would be null, when is it null vs not? What is the stack to the null-pointer.
