Abhinav,

Welcome to Java Ranch! You have marked this topic as resolved so it is unlikely you will get any responses to this topic. If this was unintentional let us know. If it was intentional it is often helpful to others to post the solution you found to your problem.

I am moving this to the ORM forum as it does not seem to be Spring related.

I have marked this topic back to unresolved for you.

You have not posted any of your configuration so its hard to say much, but I would start by making sure your entity is annotated with javax.persistence.Entity not org.hibernate.annotations.Entity (check your imports)
 
I agree. Here's the link: http://aspose.com/file-tools
