Google Web Toolkit News - onGWT.com

Stephen Callaghan

This article will show how to build a SOA-based system using Spring Services, a GWT client to talk to those services, and Maven 2 as a build tool to hold it altogether. There is also an associated reference project, created here at Shine Technologies and now open-sourced on Google Code using the Apache 2 License.

This article will start by covering the setup of a build environment using Maven. Then we'll start working through each of the layers in sequence, beginning with getting up-and-running with a compatible Spring Service layer. Next we'll add a bridge between GWT and the Spring Services. Finally, we'll introduce a GWT client that can attach to the bridging layer and thus communicate with the Spring services.

The Three Amigos - Maven, Spring and GWT

I have finally compiled a tutorial on how to make a GWT app that works
with GWT, Hibernate and Spring.

The Tutorial can be found at:

Historically, the development of Ajax web applications has been a complex process. This is due mainly to the requirement to learn and use a variety of technologies, possibly including HTML, JavaScript, XML, ASP.NET, Java servlets, various scripting languages, etc. Recently several products have emerged that make it possible to develop Ajax web applications using the Java development environment. Some use exclusively Java, while others use mainly Java. One development environment that allows you to use mainly Java for the development of web applications is the Google Web Toolkit (GWT), which is the primary topic of this tutorial lesson. Most of the client-side code for a GWT Ajax application can be written in Java. There is no requirement to write JavaScript code.
The main purpose of the tutorial is to teach you how to write the Java code necessary to accomplish event driven programming using the GWT.

Google Web Toolkit (GWT) allows ordinary Java Programmers to produce highly responsive web user interfaces, without needing to become experts in JavaScript. Here we demonstrate a little maths game for practicing your arithmetic. Included is an Easter egg.

This tutorial walks you through the process of putting together a simple GWT application from creating a GWT Java Project to deploying your module using GWT Designer.

This article describes how to integrate JFreeChart and GWT. It assumes development is being done in Eclipse. It also assumes that the reader has an understanding on how Remote Procedure Calls (RPCs) are created and accessed in GWT. For more information on this, go to the GWT Developer Guide (apparently I can't have urls in my post since I'm new, so just do a web search and find it) and follow the Remote Procedure Calls link.

I wrote this guide thinking in the user's who want's develope dynamic application's with the GWT (Google Web Toolkit) in an AMP(Apache,MySQL,PHP) environment's. The basic idea is write a small and very simple application using MySQL and PHP at the server side, and GWT for the client interfaze, using JSON for the communication between the client and the server.

AJAX applications are all the rage these days. And why not? They're simple to use, accessible from anywhere, free of sneaky installers and generally safer from the malware gremlins. But behind every good web app, there's a group of exhausted AJAX developers driven to the brink of madness with worry of browser quirks, memory leaks and load times. In this session, we'll build a small web app and demonstrate how the Google Web Toolkit relieves the nervous twitching troubling AJAX developers by allowing them to practice sound engineering using Java and Eclipse and still end up with fast, light-weight JavaScript applications.
