Bob,
It's not clear from your post where the problem is. Chances are either
you have set up the RPC servlet wrong in your module xml file (i.e. it
doesn't match ((ServiceDefTarget)
selectionSearchService).setServiceEntryPoint
(GWT.getModuleBaseURL() +
"/selectionSearchService");
so the servlet cannot be found, or there is something wrong with your
code causing an exception somewhere.
If you are running hosted mode you should see any exceptions in the
dev shell window - it should tell you if it can't find
SelectionSearchServiceImpl and how it's trying to find it. That's what
we need.
Does your program get to
public void onFailure(Throwable caught) {
setMessage("Selection search failed. ");
}
in which case what is caught.getMessage()?
