[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - Trying out Hibernate

Hi. I'm trying to use Hibernate for the first time within JBoss AS 4.0.4. I'm including hibernate-service.xml in my jboss-app.xml file in the META-INF directory of my EAR and I have an ejb jar file included in the ear that contains a mapping file. I have ScanForMappingsEnabled set to true in my hibernate-service.xml file and I can see that that's working. When JBoss starts, I can see in the server log that Hibernate is finding my mapping file. However, I don't see any log messages about anything having been mapped and when I attempt to execute a query from a SessionBean after retrieving the current session from the SessionFactory, I'm told that the class I've mapped is not mapped. I'm wondering if there's some ClassNotFoundException getting swallowed during initialization or something like that. Here's some useful log output:
from server.log:
2007-01-17 17:29:02,023 DEBUG [org.jboss.hibernate.jmx.Hibernate] Passing archive [/Applications/JBoss/jboss-4.0.4.GA/server/default/tmp/deploy/tmp53389myApp.ear-contents/myEntityEjb.jar] to Hibernate Configration2007-01-17 17:29:02,023 INFO  [org.hibernate.cfg.Configuration] Searching for mapping documents in jar: myEntityEjb.jar

I thought I'd see some output between the entries at 17:29:02,034 and 17:29:02,299 regarding what got mapped.

Here's my mapping file:

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping
	PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
	"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd" >

Here's the query from the Java code:

		try {
			Session hbmSession = MyHomeFactory.getMyInstance()
			Query q = hbmSession.createQuery("from InventoryItem a where a.productType = :pType");
			q.setShort("pType", type);
			answer = q.list();
			int size = answer.size();
			log.info("There are " + size + " inventory items of type " + type + ".");
		} catch (Exception e) {

I've tried setting priority value="TRACE" on org.hibernate in the log4j.xml file to no effect.
Can anyone give me a clue as to how I can try to solve this problem?
