    Two EJB Related Question

    Deepak Jois Newbie

      1. Can I have stateful session bean that extends a normal Java object and implements the Session bean interface, and the calls a public method in the parent class inside a business method of the bean.

      For eg

      public class AnalysisTestBean extends AnalysisObject implements SessionBean {
      
       public AnalysisTestBean() {
       super();
       }
      
       public void setSessionContext(SessionContext ctx)
       throws EJBException,
       RemoteException {
       }
      
       public void ejbRemove() throws EJBException, RemoteException {
      
       }
      
       public void ejbActivate() throws EJBException, RemoteException {
      
       }
      
       public void ejbPassivate() throws EJBException, RemoteException {
      
       }
      
       public void ejbCreate(String param) throws CreateException {
      
       }
      
       /**
       * Business method
       * @ejb.interface-method view-type = "remote"
       */
       public void analyze() {
       super.analyze();
       }
      }
      


      Here I have an Analysis parent object with ONLY a public method analyze(), no static members, and I am trying to design an EJB by inheriting it.


      2. Where do I put the Jar file containing the parent object Analysis in the Jboss distribution tree, so that it can be discovered by JBoss during deployment?

          1. yes, if the base class has a public constructor without arguments or is constructed within the beans constructor (but I would rather prefer delegation since I can't imagine why to use inheritance). And the base class must be serializable, when implementing a stateful session bean.
          2. depends on your deployment. Just deploy all your jars within one ear or just throw them into your deploy directory.
