gwt-rpc

I've written a quick GWT app with the following code: MyTaskService package com.google.gwt.mytasks.client; import com.google.gwt.core.client.GWT; import com.google.gwt.user.client.rpc.RemoteService; import com.google.gwt.user.client.rpc.RemoteServiceRelativePath; @RemoteServiceRelativePath("taskAction") public interface MyTasksService extends RemoteService { public void addTask(String title, String description); } web.xml <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd"> <web-app>

I'm currently working on a GWT application as a proof of technology for future projects. I like the way of building my AJAX code in Java instead of JavaScript. But I seem to be running into a memory problem when I repeat calls to an RPC service. The browser memory usage keeps growing and growing. When searching Google I keep reading about how great GWT is and that its impossible to get memory leaks so can anyone explain why my browser (Firefox and Chromium) memory is rocketing? Thanks in advance for helping me, Bram The code: ... class ExampleTable extends Composite private RPCService

rpc.call(mycallback); { //subsequent code block } How does the single threaded async callback work? When will the callback get called? Will the subsequent code block always finish executing before the callback is allowed to run (i.e. will the callback only run once all code has finished?)? #1 javascript is single-thread, but the browser is not, so the js-thread sends the xhr call to the browser to resolve it, and the browser returns the control to it inmediately. #2 when the browser gets the response from the server, it queues the callback into the js thread, so it will be executed when js

I'm successfully able to integrate Spring and Spring4GWT. Everything is working fine. The only problem I'm facing is How do I get HttpServletRequestObject in the @service class? Some of the configuration and code web.xml <servlet> <servlet-name>test</servlet-name> <servlet-class>org.spring4gwt.server.SpringGwtRemoteServiceServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>test</servlet-name> <url-pattern>/ui/test/*</url-pattern> </servlet-mapping> Service class public class LoginServiceImpl implements ILoginService { private IUserService

I have a Appengine connected Andorid project, to enable RPC calls between the server and the Android device. When I'm doing calls on the GWT client everything works perfectly, but when I'm doing calls from the Android app the server throws this nullpointer exception. I'm making RPC calls with a Requestfactory.
