Hibernat 2.1.6+Jboss 3.2.5:
I made a hibernate Mbean of jboss. It's sar, not har. I failed to make a call from a client app. to a session bean which uses the Hibernate Mbean by the
Lazy instantiation problem at last. Looking at the steps I passed, there are some info. usful to you guys to help me go out the problem. Thanks ahead
The Mban was deployed with
two possible problems ( marked in red color) as follows:

When I make a call from the client app. to a session bean, using code like this:
try {

System.out.println("1. create bean");
Sen sen = (Sen)myBean.load(Sen.class, new Long(166));
System.out.println("2 find Sen");
String str = sen.getStatus();
System.out.println("3 call Sen.get(.)");
System.out.println("Sen status="+sen.getName());

The session bean is like this:
public void ejbCreate() throws javax.ejb.CreateException

}

{
if( _sessionFactory == null )
{
InitialContext initialContext = new InitialContext();

sess.close();

{
logger.error( "load failed " + ex );

return ret;
}

At last when I make a call from the client app. the the session bean, The Mbean shows errors like this:

The client app log is as bellow:
------------
1. create bean
2 find Sen
Exception in thread "main" java.lang.NullPointerException
at com.gmms.ee.client.HibernateTestClient.testBean(HibernateTestClient.java:55)
at com.gmms.ee.client.HibernateTestClient.main(HibernateTestClient.java:79)
-------------------
logs of both sides show the there is no problem on the topics published on Hibernate and Jboss web site. --> The session bean get the JNDI of the mbean and even get the object of the table row. Unfortunately, When the session really retrieve the data properties of the class, the Hibernate is broken.
Another peice info may be usful: for The SEN table is the test, there is a CMP bean is deployed in the JBoss server. Does it matter? CMP and Hibernate share one DS?
Any idea is appreciated.
