Authentication successful but Authentication object is empty null

amy

Hi all
I have quot;IllegalArgumentException: null sourcequot; exception when using Websphere authentication according to the log - Authentication was successful,  
But Authentication object passed to EventObject is empty
What am I doing wrong?

Thank you!Code:

Apart from that it's almost impossible to say really from the information here. I would use a debugger to track the progress of the authentication progress and work out why a null argument is passed.
