Application Module instance...

Question

Hi ,
I face a very strange/interesting issue as follows,
I have a class which extends the ApplicationModuleImp to overrides the prepareSession and beforeDisconnect methods say class X . And I have made all the app modules to extend this class. The thing is I find too many times the prepareSession methos is called.
When I used the SOP to print the class names, I found that when other appmodules get instantiated, this Class X is also made to instantiate and call prepareSession method even though it is not an app module by itself.
Can anyone explain the reason for this behavior or is it a issue........... ?

Vijai,
You must be doing something different then - here is my test case:
public class X
  extends ApplicationModuleImpl
  public X()
    super();
  @Override
  protected void prepareSession(Session session)
    System.out.println("*******name********* (in superclass)" + this.getClass().getName());
    System.out.println("****obj*****" + this);
    super.prepareSession(session);
public class AppModuleImpl
  extends X
   * This is the default constructor (do not remove).
  public AppModuleImpl()
   * Container's getter for CountriesView1.
   * @return CountriesView1
  public ViewObjectImpl getCountriesView1()
    return (ViewObjectImpl) findViewObject("CountriesView1");
  @Override
  protected void prepareSession(Session session)
    System.out.println("*******name*********" + this.getClass().getName());
    System.out.println("****obj*****" + this);
    super.prepareSession(session);
}And the result:
*******name*********model.AppModuleImpl
****obj*****model.AppModuleImpl@3253be7c
*******name********* (in superclass)model.AppModuleImpl
****obj*****model.AppModuleImpl@3253be7c
