Question

I am running into an issue with GWT :

The exception stack looks like :

Caused by: java.lang.RuntimeException: Deferred binding failed for 'com.cme.reg.fltrs.common.service.AnnouncementService' (did you forget to inherit a required module?)

    at com.google.gwt.event.shared.HandlerManager.fireEvent(HandlerManager.java:127)

Its failing at : announcementService = GWT.create(AnnouncementService.class);
Notes:

I have my service class : AnnouncementService
@RemoteServiceRelativePath( “announcement.srvc” ) has been added to AnnouncementService.

Async service class: AnnouncementServiceAsync

Configurations.xml :

entry key="**/announcement.srvc" value-ref="announcementServiceServlet"

Any help, where I am doing wrong or missing anything ?

Thanks Thomas.
Few The things to be checked:

1.Service must have a matching ServiceAsync class
2. Make sure all types used in Service implement IsSerializable

I was missing these two condition at few places.
