Database connection closed.
Is there any solution from java programming side to resolve this issue.

Answer 1

Check your code to make sure that you're closing your Connections, Statements, and ResultSets properly. My guess is that you are not, so your application has exhausted these scarce resources.
If you don't know what "closing properly" looks like, here's a decent link:
