Problems with Session and transaction handling?

I have issue on random session close on my hibernate ejb:

Code:

public OrderHandler() throws NamingException {
logger.debug("Enter c'tor of OrderHandler()");
InitialContext ctx = new InitialContext(); 
SessionFactory sessionFac_report = new Configuration().configure().buildSessionFactory();
sesReporting = sessionFac_report.openSession(); 
} 
...

public void saveToDatabase() throws Exception { 
Transaction txReporting = null;        
try{              
   txReporting =sesReporting.beginTransaction(); 
...
}catch (Exception e) {             
if (txReporting != null) {
   // Something went wrong; discard all partial changes
   txReporting.rollback();
    }
    throw e;
   }        
}

it runs fine with small msg size (translate from a file 50 kb), and keep getting the session is closed when it reaches large msg size(translate from a file 2 Mb) with this:

Code:

Are you creating a configuration object every time you need a session?
It doesn't work that way.
The program is complaining because the original session is closed, and you try to create new ones each time.

What strategy are you using to manage your sessions?

Does something like this count?

Code:

public void onMessage(Message recvMsg)
   {...
OrderHandler oHandler = new OrderHandler(); 
...
 oHandler.saveToDatabase(); 
...
}
