Hi,
I am trying to create a dispatcher to define the access levels for the
current user. I have followed the steps from the Wiki pages:
http://wiki.apache.org/tapestry/Tapestry5HowToCreateADispatcher
http://wiki.apache.org/tapestry/Tapestry5HowToCreateADispatcher2
This seems to work. But as I try to do
asm.exists(UserPermissions.class) it returns false. I checked the
classpath for the class my.project.services.UserPermissions. And there
it does exist. I also tried to make it an interface but this didn't
work out either.
My classes:
----------------------------------------------------------------------------------------------
AccessController.java:
public class AccessController implements Dispatcher {
private ApplicationStateManager asm;
public AccessController(ApplicationStateManager asm) {
this.asm = asm;
}
public boolean dispatch(Request request, Response response) throws
IOException {
boolean canAccess = true; // to avoid the access violation for
now
if (asm.exists(UserPermissions.class)) {
UserPermissions perms = asm.get(UserPermissions.class);
canAccess = perms.canAccess(request);
}
if (!canAccess) {
throw new RuntimeException("Access violation!");
}
return false;
}
}
----------------------------------------------------------------------------------------------
UserPermissions.java:
public class UserPermissions {
public boolean canAccess(Request request) {
return true;
}
}
----------------------------------------------------------------------------------------------
AppModule.java:
public class AppModule {
public static void bind(ServiceBinder binder) {
binder.bind(AccessController.class).withId("AccessController");
}
public void
contributeMasterDispatcher(OrderedConfiguration<Dispatcher>
configuration,
@InjectService("AccessController") Dispatcher
accessController) {
configuration.add("AccessController", accessController,
"before:PageRender");
}
}
----------------------------------------------------------------------------------------------
Does anyone have a clue what I am doing wrong?
Yours,
Kasper
