Cannot Load Hibernate object
Hibernate3.0, JBoss4.0.2, JDK-1.4.2_01
I have two files. techdesk.har and techdesk.war. The har file has only three classes made persistent, and deploys correctly, and the SessionFactory bound correctly in JNDI:
2005-07-26 22:40:52,511 INFO [org.jboss.hibernate.jmx.Hibernate] SessionFactory successfully built and bound into JNDI [java:/TechDesk/SessionFactory]
However, when I access my servlet with code to load a class from hibernate, nothing comes back (not even errors or exceptions). I even have ShowSQL=true in my hibernate parameters, but no SQL statements were output'd. Here is the log from when I access the servlet:

Here is a snip of the code that calls the hibernate lookup:
Transaction tx = null;
Session session = null;
try {
InitialContext ctx = new InitialContext();
SessionFactory factory = (SessionFactory) ctx
.lookup("java:/TechDesk/SessionFactory");
session = factory.openSession();
} catch (NamingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
PrintWriter out = resp.getWriter();
tx = session.beginTransaction();
try {
List results = session.createCriteria(Ticket.class).list();
for (Iterator i = results.iterator(); i.hasNext();) {
Ticket ticket = (Ticket) i.next();
out.println(ticket.getId() + " " + ticket.getProblem());
if (ticket.getOwner() != null) {
out.println(ticket.getOwner().getUsername());
} else {
out.println("No Owner");
}
}
} catch (HibernateException e) {
e.printStackTrace();
} finally {
tx.commit();
}
Can anyone point out what I'm doing wrong? I've been staring at this code for too long, and need a fresh set of (experienced) eyes. This code works correctly outside of JBoss and Tomcat using a POJO.
Thanks so much!
