I am trying to run a dbtest but I get the following error :

This sounds like a ClassLoader conflict. I'd bet you have the javax.persistence api 1.x on the classpath somewhere, whereas Spring is trying to access ValidationMode, which was only introduced in JPA 2.0.

Since you use Maven, do mvn dependency:tree, find the artifact:

    javax.persistence
    persistence-api
    1.0

And remove it from your setup. (See Excluding Dependencies)

AFAIK there is no such general distribution for JPA 2, but you can use this Hibernate-specific version:

    org.hibernate.javax.persistence
    hibernate-jpa-2.0-api
    1.0.1.Final

OK, since that doesn't work, you still seem to have some JPA-1 version in there somewhere. In a test method, add this code:

System.out.println(EntityManager.class.getProtectionDomain()
                                      .getCodeSource()
                                      .getLocation());

See where that points you and get rid of that artifact.

Ahh, now I finally see the problem. Get rid of this:

    org.springframework
    spring-jpa
    2.0.8

and replace it with

    org.springframework
    spring-orm
    3.2.5.RELEASE

On a different note, you should set all test libraries (spring-test, easymock etc.) to

test
