Sorry, but I am repeating my question, because the error has not been rectified.
I made service and dao layers as interfaces. I didn't made any hibernate cfg xml file, but I wrote all the hibernate configurations under application context.
this is only a test program.
When I am trying to get the username and and password from entity class, the session factory points to null always. If you need more specific code just mention it.
