RE: Proper way to get ApplicationStateManager?

[Wes Bramhall]

Are you able to use Java 1.5? The way we do it is by injection using
annotations.

@InjectState("adminVisit")
Public abstract AdminVisit getAdminVisit();

We inject the visit on our base page and have a convenience method on
our base component to get it from the page. ASOs can also be accessed in
other Hivemind services by injecting the ApplicationStateManager into
the service and asking the ASM for the ASO by name.

Subject: Proper way to get ApplicationStateManager?

I need help with ASO's.

In my Application Servlet..

        public class PCTAdminApplicationServlet extends
ApplicationServlet ..

I have a static variable "asm". I have my init() method with the
following :

public void init() throws ServletException
  {
    super.init();
    .......
    Registry myRegistry = RegistryBuilder.constructDefaultRegistry();
    PCTAdminApplicationServlet.asm =
(ApplicationStateManager)myRegistry.getService(ApplicationStateManager.c
lass);
    ...
  }


Is this the proper way to do things? I'm getting a NullPointerException
when trying something like

AdminVisit aVisit = (AdminVisit)
PCTAdminApplicationServlet.asm.get("adminVisit");



Thanks,
Greg
