In the Hibernate application is it necessary to place the contact.hbm.xml file in class path.

So, you can put the contact.hbm.xml in src directory or in bin directory of your eclipse project.

So, just try out both and try to fix the error.

Remember in mind that contact.hbm.xml must be present the classpath.
