I think this might happen if you restart the context without a shutdown of the transaction manager.

If this is in a unit test, then make sure you are not running tests in parallel. By default, maven runs tests in parallel and this happens too.

thanks Guy Pardon for your reply.
i was calling the spring xml configuration file twice .

My pleasure, glad it works!
