    Second Call fails

      A struts-action makes these 2 calls in its execute-method:


      bd.executeRegistration(playerRegistrationForm);
...
bd.getInstructionsAfterRegistration();



      bd is a business-delegate. Between these 2 calls, no other method of the bd is called by the action. bd is a normal (not static) class, holding a local reference to a stateful session-bean as instance-variable called session. The 2 methods called from the action are: 

       public String executeRegistration(PlayerRegistrationForm form) throws DuplicatePKException {
 instructionsAfterRegistration = session.getInstructionsAfterRegistration();
 return session.executeRegistration(form);
 }

 public String getInstructionsAfterRegistration() {
 return session.getInstructionsAfterRegistration();
 }


      The method bd.executePlayerRegistration() is first called. In this method, both calls on the stateful sessionbean 

      session.getInstructionsAfterRegistration();
session.executeRegistration(form);


      work greatly. But when the action calls (second call) the bd.getInstructionsAfterRegistration() - method, the bd can't call session.getInstructionsAfterRegistration() again . Here is the Exception, that is thrown:

      17:00:30,805 DEBUG [PlayerRegistrationBD] getInstructionsAfterRegistration() entered

      in the EJB-JAR.XML: 
      for the session-bean:

      So: Why fails the second call, while the first works?
