org.hibernate.ejb.HibernatePersistence cannot be cast to javax.persistence.spi.PersistenceProvider

I am developing an application using SPRING 3.0.4, JPA 2, Hibernate 3.5.5.

I an trying an existing example given on link http://www.javacodegeeks.com/2010/05/jboss-42x-spring-3-jpa-hibernate.html.

only difference is that I am using latest versions of libraries and JBOSS server.

Now when I am trying to complile it using JBOSS server it gives me following error

Can anyone here help me to solve the problem.

Please let me know if you need anything else from me.

Thanks.

I personally never succeeded using JPA 2.0 with JBoss 5.1.x (due to too tight integration with JPA 1.0) although it seems possible with JBoss 4.2.

My suggestion would be to either use JBoss 6.0 M4 (at the time of writing this) and to remove all the hibernate related JARs from the webapp:

• antlr-2.7.6.jar
• commons-collections-3.1.jar
• dom4j-1.6.1.jar
• hibernate3.jar
• hibernate-jpa-2.0-api-1.0.0.Final.jar
• javassist-3.9.0.GA.jar
• jta-1.1.jar

Or to simply use Tomcat (and deploy your webapp as is) since you're not using anything from JBoss.

See also

• JBoss 5.1.0.GA, JPA 2.0, and EClipseLink 2.0 (which is not answered)
• Hibernate 3.5-Final in JBoss 5.1.0.GA

I guess you don't need hibernate-jpa-2.0-api-1.0.0.Final.jar in /WEB-INF/lib, since JBoss have its own set of JPA classes.

So, you have two sets of JPA classes loaded by different classloaders, and these classes can't be casted to each other.

I have created a workaround for this specific issue. Check it out here : How to use JPA2 on JBoss 5.x ? (or How to eliminate class loading isolation issue?)
