SEVERE: A web application registered the JBDC driver [com.mysql.jdbc.Driver] but failed to unregister it when the web application was stopped. To prevent a memory leak, the JDBC Driver has been forcibly unregistered.
Please tell me how to solve this.I tried a lot to solve it But i was not able to solve this error.

Basically, you are trying to register the same MBean twice under the same name. Don't do that.
Either rename one of the instances, or do not deploy the webapp twice. Also check the code that this MBean is properly removed when a webapp is undeployed.
