Hi,

What is the name of mapping (model) class file? Is it CONTACT.java?

In this you are writing table name in query. You have to write the name of java class file in query.

You query should:

String hql="delete from Contact c where ID=6";
         Query query=session.createQuery(hql);

Where Contact is the name of java class file.

Thanks
