Hi everybody,
I'm trying to deploy an EAR with a new version of hibernate and I'm encountering some problems with class loading (I've read the articles on the wiki but it didn't help).
I've installed a fresh version of JBoss 4.2.3.GA.
ear-deployer is configured with default values (isolated = false, callByValue = false, javaee5lib=true).
I deploy an EAR with isolated class loading with following configuration:
My jboss-app file
| <jboss-app>
| <loader-repository>
| com.example:loader=example-loader
| <loader-repository-config>
| java2ParentDelegation=false
| </loader-repository-config>
| </loader-repository>
| </jboss-app>
|
I've a lib directory with following jars:
- hibernate-entitymanager-3.3.1.ga.jar
- hibernate-annotations-3.3.0.ga.jar
- hibernate-common-annotations-3.0.0.GA.jar
- hibernate-3.2.4.sp1.jar
- hibernate-validator-3.0.0.GA.jar
- ejb3-persistence-1.0.1.GA.jar
- jasperreports.jar
- drools-compiler.jar
- drools-core.jar
When I deploy my app, I've a ClassCastException for HibernatePersistence because the entitymanager jar is loaded twice: once from the default lib of jboss and once from the ear lib. How is it possible with my jboss-app configured with isolated class loading and no parent delegation ?

It looks like the ejb3 deployer requires the loading of jboss-ejb3.jar located in server\default\deploy\ejb3.deployer which then requires the loading of some dependencies like hibernate-entitymanager from the jboss default lib. Only after my own hibernate-entitymanager is loaded resulting in a ClassCastException.
Can somebody explain me what I'm missing here and how I can solve this?
Thanks a lot,
Michael
