If any body uses hibernate 3.5 and WAS then they should use the version 7.0.0.15 which can support JPA2.0 as hibernate 3.5 uses JPA2.0.

Hey Rodrigo! All the steps I took to resolve our issue is written here. Have you tried the steps outlined above? What errors did you find?

I have the same problem (Hibernate 3.5, Spring 3..0.2) and i need to use Websphere 7.
I need this version of hibernate. Do you have any idea?

Hi Mike,

If you’re using Hibernate and getting that error message, make sure you’re doing the 2nd bullet point in the solution above. WebSphere uses OpenJPA, by default.

Good luck!

Hi mihaela,

WebSphere 7.0.0.7 supports Java EE 5, which includes JPA 1.0. Hibernate 3.5.0-Final uses JPA 2.0. Therefore, with just the Hibernate JARs in your application, I don’t think it will work with WebSphere 7.x. I checked the Hibernate Entity Manager documentation for 3.5 (http://docs.jboss.org/hibernate/stable/entitymanager/reference/en/html_single/#configuration) and they have provided a Hibernate JPA JAR that you would need to add to your classpath, if you’re not running on a JEE6 server. Just to mention, it would be difficult to remove the JPA JAR from WebSphere, since there is none. The persistence API is bundled in with j2ee.jar.

I did take the liberty to plug in Hibernate 3.5.0-Final into our existing configuration (without the JPA JAR) and the application did fail to run. Unfortunately, I did not have enough time today to try and muck with the classpaths. I’ll let you know when I get the chance.

Good luck! Let me know how it goes.

Hello,

Do you know if Hibernate 3.5.0-Final may be used as JPA provider on WebSphere 7.0.0.7? I am working on a project with seam 2.2.0, hibernate 3.5.0-Final, DB2 as database server and Websphere 7.0.0.7 and I cannot obtain an EntityManager injected with @PersistenceContext. Until now we have worked with the Seam EntityManager but we are facing strange behaviour when inserting data with ManyToMany relations and OneToMany with join tables. It doesn’t insert the values in the join table.

I don’t know where is the problem. Any hints will be helpful.
Thanks in advance.
