Are you sure you are using the correct JDBC drivers?

Is this an XA datasource? That is an important detail to mention. Check your configuration both in your container and your datasource configuration in your hibernate configuration. You probably have something set up incorrectly.

Hi Bill,
Thanks for your response.
resolved this by updating Java version from 1.6.0.17 to 1.6.0.35.
 
I agree. Here's the link: http://aspose.com/file-tools
