Hello,

I have been banging my head against a problem that seems to be a JBoss -Hibernate class loader problem for a couple days now. (Note, for reason I don't care to go into, I can not use the JBoss MBean configuration option.)

I am trying to configure my hibernate session factory in the following way:

Configuration cfg = new Configuration().addClass(PurchaseOrderImpl.class);
SessionFactory sessFac = cfg.buildSessionFactory();

When I fire up my application in jboss I get the following stack trace:




I am using JBoss 3.2.1, and I have the following jars (among others) in my server's lib dir:

commons-collections.jar
commons-lang.jar
commons-logging.jar
cglib-asm.jar
hibernate2.jar
odmg.jar

In WEB-INF/lib and WEB-INF/classes I have all of my applicatioin code, including my hibernate specific dao, whos factory is blowing up durring initialization. Also, note that the mapping file that can not be found (PurchaseOrderImpl.hbm.xml) is sitting right next to the class (PurchaseOrderImpl.class) under WEB-INF/classes, which is being successfully loaded.

Hibernate version is 2.0.3

Any insight would be greatly appreciated!

As it turned out, I had a bug in my ant script where a jar was getting built with all the code, but none of the resources (i.e. no hibernate mapping files). I didn't realize the jar had the hibernate and Dao code in it, I thought that code only live in WEB-INF/classes... Anyway, this explains why the class loader couldn't find the resource files.

The moral of the story is that a quick code review (even a review of your build script that has seemed to work perfectly for so long) can save hours and even sometimes days in the trial-and-error debug cycle!

Thanks,

Troy
