RE: Re : Unknown entity and SessionFactory null

Hi Angela,

Looks liek you didnt specify any entities in your hibernate cfg mapping file.

If you model an entity under your model/entity package, yes you need to tell 
your AppModule.JAVA about that directory...

But you also need to tell hibernate about those entities.

We do this by specifying them in our hibernate.cfg.xml

Here is mine..
