Struggling with Acegi authentication....

Hey guys!!!

I'm completely new to using Spring, Hibernate and Acegi security. I've gotten a hang of Spring and Hibernate, so that's not a problem. ...but, I'm really really struggling with Acegi security. I'm trying to write validation code for my web application using Acegi security. Here's what I want to do:

1) Validate the username/password against my DB2 database using spring and Hibernate (e.g. Cbo & Dao objects).

2) Verify the user has security roles to access certain pages.

My problem is figuring out how to configure the applicationContext.xml file and how to implement AuthenticationDao, PasswordAuthenticationDao or JdbcDaoImpl to read in the username/password.

I can't find examples for show how to implement this approach using Acegi and most of the ones I see use InMemoryDaoImpl, which I don't want.
Please please....I'll appreciate all the guidance you can give me to figure this out.

Here's the code I have so far:
