Access Bean

An AccessBean is the implementation in VisualAge for Java of SeshKumar 's ClientViewOfEjb idiom. It basically is a wrapper for an Enterprise Java Bean that implements the methods in the Remote Interface of the EJB as methods of a JavaBean. The methods in the Home Interface become constructors to the class or static members (in the case of findByXXX methods).

It sort of works like this:

public class MyEJBWrapperBean {

 private MyEJB ejb;

 MyEJBWrapperBean(String arg) {
   // do the initial context lookup
   // obtain the home (MyEJBWrapperHome)
   ejb = MyEJBWrapperHome.create(arg);
  }

  String doFoo(int arg) {
    // pass-through method to the underlying ejb   String result = null;
   try {
     result = ejb.doFoo(arg);
   } catch (RemoteException e) {}
    return result;
  }

}

Hopefully you get the picture... You generate these things by selecting an EJB inside VA's EJB Development Environment tab and clicking on "Add-->AccessBean".
