What is problem?

You need to do more debugging. Make sure you are catching and logging or printing out exceptions. They should indicate a more specific problem. Make sure you have all the needed drivers and depended libraries in the class path of the .jar you are trying to run.

May be you missed to pack MySql jar in your jar.
