Hi,
we are considering to use Jboss 4.0 (using Hibernate) in our future 
developements. We have successfully compiled and executed a small java app 
using just Hibernate.  However, we have been unable to port that small app to 
Hibernate on Jboss.
Using the JBoss 4.0 manual, and googling around, I think we have correctly 
configured and deployed our app in Jboss (then, maybe not, because it's not 
working). However, when we try to execute a simple query, this is the resulting 
error:

12:00:23,651 ERROR [LogInterceptor] EJBException in method: public abstract 
java.util.List 
com.aitanasbs.conexion400.interfaces.Fachada.getArticulos(java.lang.String) 
throws java.rmi.RemoteException:
  | javax.ejb.EJBException: in expected: ob [from CdCliente ob where 
ob.CdClienteApellidos like '%Rafael%']

We have both tried to connect to a MySQL and a DB2-400 database, and we are 
always getting the same error. Could anybody help us to find what the problem 
is? :-(

This is the code that executes the query (we are using the classes created by 
the Eclipse plug-in Hibernate Synchronizer):

Context ctx = new InitialContext();
  | SessionFactory factory = 
(SessionFactory)ctx.lookup("java:/hibernate/SessionFactory");
  | Session hsession = factory.openSession();
  | return hsession.find("from CdCliente ob where ob.CdClienteApellidos like 
'%Rafael%'");
  | 

We are using MySQL 4.1 + JBoss 4.0 on Windows, and developing with JBoss-IDE.
