Spring Security implementaion for a web application ?

We are developing java based Web application having different users

we have classified the users on role basis.

Roles defined as below:

1. Office Admin - Admin can access entire application screens and links related to particular office

2. Senior Employee-this employee should access particular screens and links where permissions allowed by Office Admin

3. Normal Employee-this employee should access particular screens and links where permissions allowed by Senior Employee

Query: 1. How to define role permissions using Spring Security?

2. Is it possible screen/jsp page locking using Spring security?

3. How many ways spring security can be implemented for (domain, screen , table ) permissions or locking?

Please find the attached screen shot and anyone can give better solution , it will be great for me.

Thanks ,

Hmm im no expert, but iv tried using spring security (and is still using it now).

This reference is quite straign forward.

Basically you need these fields: username, password, role and enabled defined in your database.

and im not sure spring security is capable of page/jsp locking. i think not.
