Answer 1

It would depend on what property is giving you the NullPointerException (NPE). If you're using Spring MVC then it's likely that your DAO or Manager is giving you the NPE because it hasn't been initialized before you attempt to use it.

Could you share your the code in your Controller where you declare either your DAO or Manager?

Okay, looking at your code I would imagine you're receiving your NPE at this line:

ArrayList list = (ArrayList)edao.findAll();

I would begin looking at the EmpJB class and ensure you have all of the dependent properties initialized.
