User Management for Google App Engine Java

Question

I am using GAE Java for a multi-user application. There are several users with different roles. Each user can log in, perform some operations and log out. The business limits me to using the Google User Service, and I need to implement my own for authentication and session management.

Can someone please share with me how I should implement my own user management? I read it is very difficult to implement my own user management. Any pointers in terms of best approaches / design / existing structures, if any?

I could see some similar messages, but they are intended for python.

Well, to authenticate the quality and security of the product, I finally decided to use "Spring-Security". This seems to be the best solution if you use spring in your application and can perform settings at the best levels.
