        Key: HB-330
    Summary: Loading mapping files from ManagedConnectionFactoryImpl in WebLogic
       Type: Bug

     Status: Assigned
   Priority: Minor

    Project: Hibernate2
 Components: 
             core
   Versions:
             2.0.1

Environment: Windows 2000, WebLogic 8.1 (on windows 2000)

Description:
ManagedConnectionFactoryImpl.initialize() passes the contextClassLoader from the thread to load the mapping files in Configuration.addResource.
This works fine (in both JBoss and WebLogic) IF the mapping files are on the class path of the application server.

It also works on JBoss when the mapping files are packaged with the connector deployment (-ds.xml).  (The mapping files are found through JBoss' UnifiedClassLoader architecture.)

However, in WebLogic, the configuration files are not found when they are packaged with the individual deployment.  This seems to be because the thread that deploys the component corresponds to the root thread on the application server, and therefore uses the Launcher$AppClassLoader.  The actual class loader used to load the deployed connector (GenericClassLoader) is managed by the deploymer components of weblogic.

Changin the class loader passed to Configuration.addResource by the ManagedConnectionFactoryImpl to getClass().getClassLoader() seems to result in the desired ability to load the mapping files from the deployment directory.
Since the ManagedConnectionFactoryImpl is only used when deploying to an application server, I would assume that this has no adverse affects and it seems correct, but these class loader issues are quite mind boggling.
