problem in database connection

[Joseph Bashir]

I am using mysql and hibernate. While running my application, if there is an error or exception thrown, the connection with the database is lost and the connection is not restored until I restart the tomcat. Can somebody please tell me why it happens and how to overcome this problem.

Thanks.

Why do you think the database connection is lost? What exception is thrown if you try to execute a select statement?
