DataBase connection interupted while application is running using JPA

[Esaki muthu]

I am running the application and after that now the database connection is not received .At this time i see application is idle and i see the progress bar running.

How can i achieve that the database connection is cut at this time.because the no error is displayed in log.


I want an exception regarding this to cath and inform the user that DBConnection is Failed

Is the connection doing something when it cuts out? If it is idle this is called time out and is a natural life cycle event.

No .It does not do anything .That is after connection is cut i just click an screen in application it is still loading ...but i want to catch this an display an message to the user that database connection is cut ...
