This document is for developers interested in logging client-side code in their GWT applications. Logging is the process of recording events in an application to provide an audit trail to understand how the application executes and to diagnose problems. Logging makes it easier to troubleshoot issues encountered by developers and users. The following sections walk through a logging example application and introduce the basic functionality of the Logging framework and configuration options. Developers should already be familiar with developing a GWT application. Overview of the Logging Framework Developer's Guide - Logging - Google Web Toolkit

Google™ Web Toolkit Applications: InformIT “Ryan clearly understands the GWT value proposition and how GWT integrates into a diverse web technology stack–and not just in a theoretical way. With the popularity of gpokr.com and kdice.com, Ryan can speak with the authority of concrete success.” –Bruce Johnson, creator of Google Web Toolkit “This book distinguishes itself from other books on GWT in that it walks through the entire process of building several nontrivial GWT applications, not the toy applications that most books present.” –R. Mark Volkmann, Object Computing, Inc. “Google™ Web Toolkit Applications is an excellent resource for any GWT developer.
HTML color codes are hexadecimal triplets representing the colors red, green, and blue (#RRGGBB). For example, in the color red, the color code is #FF0000, which is '255' red, '0' green, and '0' blue. These color codes can be used to change the color of the background, text, and tables on a web page. Major hexadecimal color codes Below, are some of the common color names and codes.

GWT Developer's Plugin for Firefox 14
How To Downgrade Firefox? Dear Firefox users, I have upgraded to the latest version of Firefox recently. After upgrading to Firefox 10, Firefox is crashing a lot. I tried to disable all installed add-ons, but failed to get any solution. I want to downgrade to Firefox 9 now. But, I am totally clueless about the downgrading process. I wish that there should be an option to downgrade Firefox to a specific version easily.
GWT Java Game Coding Basics: The GameLooper The first class I am going to code for my game is what I am calling the 'GameLooper'. The GameLooper will handle a never ending (unless paused) while loop. At this point I'd like to acknowledge the great work by Mark Wilcox at Rebel Ideas who has kindly left his game "Hoth Strike" open source and un-obsfucated. It saved me a good couple of hours headache around looping. The gaming mechanics will behave much like a television screen, the game looping will calculate if the FPS (frames per second) is too high (not much we can do about low FPS), cap if is it is too high, and then animate the next frame, rinse and repeat.
At this point, you've created the initial implementation of the StockWatcher application, simulating stock data in the client-side code. In this section, you'll deploy this application on Google App Engine. Also, you'll learn about some of the App Engine service APIs and use them to personalize the StockWatcher application so that users can log into their Google Account and retrieve their list of stocks. Note: For a broader guide to deploying, see Deploy a GWT Application. This tutorial builds on the GWT concepts and the StockWatcher application created in the Build a Sample GWT Application tutorial.

Uploading Your Application - Google App Engine
App Engine Datastore is a schemaless object datastore providing robust, scalable storage for your web application, with the following features: No planned downtime Atomic transactions High availability of reads and writes Strong consistency for reads and ancestor queries Eventual consistency for all other queries The Java Datastore SDK includes implementations of the Java Data Objects (JDO) and Java Persistence API (JPA) interfaces, as well as a low-level Datastore API. The primary data repository is the High Replication Datastore (HRD), in which data is replicated across multiple datacenters using a system based on the Paxos algorithm. This provides a high level of availability for reads and writes. Storing Data - Google App Engine
RequestFactory is an alternative to GWT-RPC for creating data-oriented services. RequestFactory and its related interfaces (RequestContext and EntityProxy) make it easy to build data-oriented (CRUD) apps with an ORM-like interface on the client. It is designed to be used with an ORM layer like JDO or JPA on the server, although this is not required. RequestFactory
Layouts Panels in GWT are much like their layout counterparts in other user interface libraries. The main difference is that GWT panels use HTML elements to lay out their child widgets. Panels contain widgets and other panels.
LoginSecurityFAQ - google-web-toolkit-incubator - Explains how to do logins with GWT in a secure fashion. - The Official incubator of widgets and libraries for Google Web Toolkit This FAQ page is slightly more hands-on, but you should definitely also read Security for GWT applications. This article describes how to do the following: Create a 'login' page that is based on user/password authentication. Store this data in a secure fashion on your server. Allow users to 'remain logged in' for as long as you want so they don't have to enter their user name and password every time.
