[jboss-user] [Messaging, JMS & JBossMQ] - Re: Bug: Injected EJB objects instantiated on every MDB call

[doktora]

I'd bet my software hat on it.

I've added some sop's to the constructors of CalculatorMDB and RecordManagerBean just to make sure that the container is playing by the rules when calling postConstruct:

 CalculatorMDB() {
  |     System.out.println("CalculatorMDB() CONSTRUCTOR");
  |   }
  | 
  |   RecordManagerBean() {
  |     System.out.println("RecordManagerBean::CONSTRUCTOR()");
  |   }
  | 

And here is the output from hitting the "Calculate" button three times on /EJB3Trail/serviceobjects/injection/calculator.jsp

One CalculatorMDB object was created and four (?) RecordManagerBean objects. 

Doesn't seem right to me.
