          Hey,

Looking for feedback on best way to implement a login action mechanism using Struts2/Spring/JPA

Initially I had declared userName and userPassword setters inside my action class and proceeded to call
a validateUser method inside my userService class.

the userService class injects a userdao object and I validate through calling the userdao method validate(String username, String password).

This validate method instantiates a new UserEntity object and a query is performed (jpa) grabbing all entities where login = username (which will be a single entity since username must be unique).

I have this approach working. I would like to know if there is a better way to do this though. Perhaps by declaring a UserEntity obj inside my LoginAction class and having setters called for this obj.

Then I could change my validate to pass along the new UserEntity obj via validate(UserEntity user).
My problem is I'm not entirely sure how I would compare against data in my db using JPA?

Would your validate method then have a findAll() method and then iterate through the list comparing against new UserEntity obj? That make sense?

That would seem very poor though to be since a large userlist could be taxing to iterate over.

Any guidance or tips? :)

Thanks all!

Paul
