Answer 1

You are mixing artifacts from Spring 2.x and 3.x.

Replace old versions of spring-hibernate3 and spring-jpa with

<dependency>
     <groupId>org.springframework</groupId>
     <artifactId>spring-orm</artifactId>
     <version>${spring.version}</version>
     <scope>compile</scope>
</dependency> 

Answer 2

I had a very similar problem with Hibernate 4.x, Spring 3.x, JPA 2.x, and CXF 2.7.5. I removed the reference to the spring-jpa artifact in my maven POM file, and inserted your recommended snippet. Worked magic! I no longer see the exception. Thanks!

Answer 3

I had exactly the same problem. I was hibernate validator (4.2), tomcat 6 and spring 3.0.6. But I also upgraded hibernate from 3.2 to 3.6, but I forgot to remove the hibernate-entitymanager.jar (which is an old hibernate jar) from the classpath.
