Developing web application under STS 3.4.0.RELEASE (Spring). I have working JPA example under Eclipse Juno and want to port it as part of Spring application. I have to copy persistence.xml file. Where should it be located exactly?

So far I get "javax.persistence.PersistenceException: No Persistence provider for EntityManager named ..." which may be related to location or may be not.

Is there a need for "provider" element and if so what should be the value? (It worked fine under Eclipse without that element).

Please Help!!!

The persistence.xml file should be placed in META-INF/persistence.xml in your classpath.
