Hi!
I am using EJB3 persistence API's to create my entities ie JPA. However, I am not using the complete EJB3 architecture of session beans, entities etc. I want to use hibernate as my persistence provider. My client will be a standalone java program which will be calling my entities. Has anybody worked on this architecture?
My doubt is:
1) I have created a jar with these entities and persistence.xml configuration file. Within my persistence.xml file, I am using hibernate properties like hibernate.connection.username, hibernate.connection.password etc. I have no separate hibernate.cfg.xml file. If somebody has used it, then please tell me whether the procedure I am following is correct or not.
2) I am using jboss cache as my 2nd level caching. When I compile my java program with the entity jar in my classpath, it compiles without giving error. But when I run it, it gives me error:
Exception in thread "main" javax.persistence.PersistenceException: org.hibernate.HibernateException: Could not instantiate TransactionManagerLookup 'org.jboss.cache.TransactionManagerLookup'
at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:720)

at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:51)
at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:33)
at TestPersistence.main(TestPersistence.java:18)


My persistence.xml file has the following properties:
<property name="hibernate.cache.use_second_level_cache" value="true" />
<property name="hibernate.cache.provider_class" value = "org.hibernate.cache.TreeCacheProvider"/>
<!-- JBoss Cache configuration file name -->
<property name="hibernate.cache.provider_configuration_file_resource_path" value="cache-config.xml" />

<property name="hibernate.transaction.manager_lookup_class" value="org.jboss.cache.TransactionManagerLookup" />
<property name="hibernate.generate_statistics" value="true" />
<property name="hibernate.cache.use_structured_entries" value="true" />


"cache-config.xml" file is in my META-INF.

I will be thankful if someone could sugest me a solution

Maybe this will be helpful
hibernate.transaction.manager_lookup_class = org.hibernate.transaction.JBossTransactionManagerLookup

Thanks jsshop for the information..
My problem is that I am still getting that error when I use jboss cache as my 2nd level caching mechanism
