Are you still using the provided GreetingServiceImpl on server side
that expects a GWT RPC call?
yes. that code is the same except for choosing a response to send to
the client.
Because the way you're setting this up is not sending a GWT RPC
request, you're just get/put/post'ing that plaintext
request. It's perfectly valid to do that, but if your GreetingService
servlet is
still extending RemoteServiceServlet it's going to be expecting a GWT
RPC request..hence the check for 'text/x-gwt-rpc' content-type..and
reject your non-RPC request.
If you want to stick with GWT RPC, you don't use RequestBuilder like
this.
ok.
i am a newbie, so i don't really know. so far all of the stuff that i
want to send and receive is just strings.
Based on just your simple use case for timing out an RPC call you can
do something like this with an RpcRequestBuilder implementation that
sets the request timeout to 60000:
ServiceDefTarget async = GWT.create(MyAsync.class);
async.setRpcRequestBuilder(builder);
((MyAsync) async).method(data, callback);
i will try this.
thanks
