MuleESB -3.4 CE : jpa and hibernate version support? - spring

Question

I test a POC with Service include in Mule like bean spring, I have a issue with Hibernate and Jpa dependencies. Every body now which version of Hibernate and JPA are supported/use in Mule 3.4 CE.
I have a lot of exception when i wan't to run the flow : whith hibernate 3.6.0.Final :

My spring service run in test context whithout muleESB, is OK.

Answer 1

Mule distribution contains Hibernate core JARs at ${MULE_HOME}/lib/opt. But for some reason it doesn't contain Hibernate entity manager JAR. So, if you include hibernate-entitymanager.jar-4.0.1.Final in your classpath, it will try to access core hibernate classes from ${MULE_HOME}/lib/opt JARs which has been loaded by a different classloader and thus gives java.lang.IllegalAccessError.
Solution is to delete Mule provided Hibernate JARs from ${MULE_HOME}/lib/opt and add your own. Please ensure that you have a backup before you carry out such operation.

Answer 2

the suppression of hibernate-core-3.6.0.Final.jar in /opt/mule help to run muleEsb.

Answer 3

As pointed out by mmeyer this is a Class Loader issue. You can fix this in Mule 3.2 Mule provides a Fine Grained Class Loading option. To fix the above we can provide the following property in src/main/app/mule-deploy.properties and it loads both org.hibernate.engine.CascadeStyle and org.hibernate.engine.EJB3CascadeStyle using the application class loader:
FIX: Add the following to src/main/app/mule-deploy.properties
loader.override=org.hibernate
Note: Mule Studio still continues with this issue and hence one has to add hibernate entity manager jar to \MuleStudio\plugins\org.mule.tooling.server.3.4.1.ee_3.4.1.201312062152\mule\opt
My observation using mule CE standalone:
Scenario 1: (Deployment Fails)
My Mule App /lib
- has hibernate-entitymanager-3.6.0.Final .
- I excluded all other hibernate jars including hibernate-core-3.6.0.Final.jar
MuleCE3.4.0/lib/opt
- has hibernate-core-3.6.0.Final.jar and other hibernate jars
Error when app is deployed:
Caused by: org.mule.api.config.ConfigurationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [persistenceContext.xml]: Invocation of init method failed; nested exception is java.lang.IllegalAccessError: tried to access method org.hibernate.engine.CascadeStyle.()V from class org.hibernate.engine.EJB3CascadeStyle$1 (org.mule.api.lifecycle.InitialisationException)
Scenario 2 (Deployment Successful)
My Mule App /lib
- has hibernate-entitymanager-3.6.0.Final .
- I excluded all other hibernate jars including hibernate-core-3.6.0.Final.jar
MuleCE3.4.0/lib/opt
- has hibernate-core-3.6.0.Final.jar and other hibernate jars
- [Different from Scenario 1] Copy hibernate-entitymanager-3.6.0.Final to MuleCE/lib/opt
