Friends, My project is based on online banking.

In this project,i need one code to make session's part work.

Suppose, when the user log's -in to check his account status, and suddenly the power goes off, then how his data is protected?

How the session can be automatically terminated and logg's off the application opened by the USER?

Please Help me with your answer's.And I hope this is really a useful question for every JAVA Programmer.
