Google_Web_Toolkit

Google ウェブ ツールキット（GWT）は、Google の AJAX 開発ツールです。そして、Java 開発者の目標とされます。

ウェブアプリケーション（GUIとRPC）は、GWT API を使用している Java で記述されます。Java ファイルは、それからコンパクトな、混乱する、ブラウザに特有の JavaScript ファイルに編集されます。JavaScript をロードする小さなビットは、どのブラウザに特有のスクリプトファイルがユーザーエージェントに従い使われるかについて決定します。

API libray は、Apache ライセンス2.0 の下で認可されます。GWT-Compiler は、当初、所有者の免許の下で認可されました。最新版は、アパッチ2.0 の下でも認可されるライセンス。

The Google Web Toolkit (GWT) is an AJAX development tool from Google, targeted for Java developers. Web applications (both GUIs and RPCs) are written in Java using the GWT API. The Java files are then compiled into compact, obfuscated, browser-specific JavaScript files. A small bit of loading JavaScript determines which browser-specific script file gets used depending on the user-agent. The API libray is licensed under the Apache License 2.0. The GWT-Compiler was originally licensed under a proprietary license, but the most recent version is also licensed under the Apache 2.0 License.

サードパーティのライブラリ / Third-party libraries[]

As of Janurary 2010, Ext GWT, Smart GWT and GWT-Ext are the most used and cool widget frameworks on top of the GWT.[1]

Ext GWTExt GWT (a.k.a. GXT) is a GWT widget library based on the Ext Js look and feel, but developed as pure Java GWT. Ext GWT is lighter and faster than GWT-Ext. Ext GWT is based on the previously independent, pure-Java/GWT MyGWT project by Darrell Meyer, who (as of May 2010) is part of Ext Js, Inc.License: GPLv3 and commercial[2] (Ext JS was controversially switched from LGPL to GPLv3)Creator: Ext JS, Inc. (Jack Slocum)Smart GWTSmart GWT is a wrapper library for the SmartClient JavaScript library. Smart GWT supersedes GWT-Ext.License: LGPL and commercialCreator: Sanjiv JivanGWT-ExtGWT-Ext is a wrapper library for the Ext JS JavaScript library. It was superseded by Smart GWT circa November 2008. The support forum on gwt-ext.com closed at the end of 2009. Jack Slocum, author of Ext JS, supposedly pressured Sanjiv Jivan to switch GWT-Ext from LGPL to GPL, but Jivan refused.License: LGPL, making it compatible with Ext JS 2.0.2 (LGPL) but not newer versions (GPLv3)Creator: Sanjiv Jivan

ウィジェット / Widgets[]

The GWT has only a small set of 20 widgets but it is very easy to extend. There is already a large list of open source extensions. If you have written your own widget then you can add it to the list. If you have no place to host your component then you can save it in this Wiki. If you host it in this Wiki then it will be license under the public domain. If you want save it under LGPL then you can add it to the GWT Component Library.

プラグイン / Plugins[]

The support for the different integrated development environments (IDEs) and tools is very poor currently. But there are some plugins under construction. Here is a list of such plugins. If we have overlooked one then add it.

• Google eclipse plugin for gwt and app engine
• Cypal Studio for GWT A plugin for Eclipse.
• GWT4WTP Construction of a visual designer for Eclipse.
• GWT Studio A plugin for IntelliJ IDEA.
• AJAX Developer Suite A Maven plugin.
• GWT Designer A plugin for Eclipse
• GDevelop A plugin for Oracle JDeveloper
• GWT4NB A plugin for Netbeans IDE
• hibernate4gwt A plugin for hibernate

ツール / Tools[]

• Ant task for GWT
• XDoclet module for GWT Used to generate service interfaces automatically.
• GWanTed Create and use GWT widgets directly from JavaScript.

他の言語のために / For other languages[]

• GWTPHP is a PHP port for GWT Server (RemoteServiceServlet). With GWTPHP you can connect GWT application with PHP. It decodes/encodes GWT requests/responses using the GWT native data interchange format. No JSON or XML-RPC is needed.
• Pyjamas In exactly the same way that GWT is a Java-to-JavaScript compiler and AJAX widget set, Pyjamas is a Python-to-JavaScript compiler and AJAX widget set (with an identical API to that of GWT's widget API). In 2008, Pyjamas was ported to the desktop, bypassing all of the JavaScript completely.
• RubyJS, a port of GWT to Ruby
