I am trying to access DB by hibernate through JBoss DataSource in order to get benefit of connection pooling. But encounter problem now.
When I lookup SessionFactory from JBoss server, through my java code like this:
Code:
public String getCompany(Integer custno) {
String company = "";
try {
Properties env = new Properties();
env.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
env.put(Context.PROVIDER_URL, "jnp://localhost:1099");
InitialContext ctx = new InitialContext(env);
SessionFactory sessionFactory = (SessionFactory)ctx.lookup("java:/HibernateFactory"); // Error here.
Session session = sessionFactory.getCurrentSession();
Customer customer = (Customer) session.get(Customer.class, custno);
if (customer != null) {
company = customer.getCompany();
}
} catch (NamingException e) {
e.printStackTrace();
}
return company;
}
The error messages are:
Code:

While application console told me that HibernateFactory not bound, JBoss console told me that HibernateFactory is bound indeed when it starts up.
Code:
JBoss startup console:--

May be some configuration file is missing, I post related xml files here.
Hope there are helpful to explain my mistake.
Code:
jboss-service.xml:--

Please help. Thank you very much.
