The registry is stored in the servlet context.
You can retreived it by :
String REGISTRY_KEY_PREFIX =
"org.apache.tapestry.Registry:";
ServletContext context = getServletContext();
Registry registry = (Registry)
context.getAttribute(REGISTRY_KEY_PREFIX +
"testPojoASO");
IInjectEnhancementWorker stateWorker =
(IInjectEnhancementWorker)
registry.getService(IInjectEnhancementWorker.class);
(In your case you need to replace testPojoASO by the
servlet name in web.xml.)
In your orginal post,
you have a custom ApplicationServlet.
I have try the following approach with the code in
your orginal post.
Step 1) Use the framework ApplicationServlet.
Step 2) Retrieve the registry as described above.
Then I have no problem retrieving the stateWorker in
the Home page using the
above method. (As long as you have access to the
context servlet, you can get stateWorker.)
Joseph : I am sending your a war file (binary and
source) of the above example off the list.
