Performing form based authentication with entities

Question

Hey everyone,
Im in a major dilemma.Im trying to perform form-based authentication using entities.I have created the entity class from the database,and I used a SLSB to access the bean method via JNDI(when I tried using dependency injection,there was an exception).I also cannot use hibernate as a persistent provider.I used toplink since it is the default in netbeans 5.5.1 and it did not raise any issues.But then,I noticed that toplink is most compatible with the oracle application server,and I use sun java system application server 9.1.I have not been able to successfully perform the authentication.
here's the code:note,there are still bugs as ive been going back and forth trying to find a solution and also because Ive been working with preexisting code.
