Google Web Toolkit (GWT) 2.0 includes several new features that improve developer productivity and application performance. These include running GWT applications directly in hosted mode within the browser, faster compilation times, developer-guided ways to split applications into modules for deferred loading, and generated deferred JavaScript that improves load performance. GWT 2.0 also features CSS with conditional processing, declarative user interface binding, and compiler optimizations like disabling class metadata checks and cast checking to reduce script size and improve speeds.

- 1. Google Web Toolkit PGT T3CHNOLOGY SCOUTING Mit Adwords und Google Wave sind die ersten großen GWT basierten Anwendungen von Google erschienen. Mit einem optimierenden Kompiler und pfiffige Codegeneratoren werden mit GWT maßgeschneiderte JavaScript Anwendungen erstellt, die Entwicklung findet allerdings in Java statt. In dem Vortrag werden Konzepte, Neuigkeiten aus 2.0 und die aus Adwords gewonnenen Architektur Best Practices vorgestellt. © 2009 Papick G. Taboada | pgt technology scouting GmbH | http://pgt.de

Google Web Toolkit Google Web Toolkit (GWT) is an open source Java development framework that lets you escape the matrix of technologies that make writing AJAX applications so difficult and error prone. With GWT, you can develop and debug AJAX applications in the Java language using the Java development tools of your choice. When you deploy your application to production, the GWT compiler translates your Java application to browser-compliant JavaScript and HTML. © 2009 Papick G.

Editor's Notes
- Hard to define – what is the web 2.0? Set of public web applications? Survivors of the .com crash? Set of Buzzwords? Set of technologies used?
- What are Web 2.0 Apps, and where did they come from? DoubleClick → Google AdSense Ofoto (Kodakgallery) → Flickr „Akamai → BitTorrent mp3.com → Napster (iTunes?) Britannica Online → Wikipedia personal websites → blogging Evite → Upcoming.org and EVDB domain name speculation → search engine optimization page views → cost per click screen scraping → web services publishing → participation content management systems → wikis directories (”taxonomy“) → tagging (”folksonomy“) stickiness → syndication
- Web 2.0 buzzwords we probably should know... RSS Atom Trackbacks Pingbacks Social bookmarking Podcasting (audio, video) Blogs, blogosphere RIAs – Rich Internet Applications
- Builds on known DHTML technologies HTML Javascript CSS Less plugin based… no Java applets no Flash applets etc…
- Rich user experience by great ideas by great user interface by good services by low pricing
- Mashups More than eye candy Integration happens “on the client” Browser as runtime engine JS as programming language (outch) Google (and others) as service providers
- No Plugins Just Javascript, HTML and CSS

- Browsers where dumb html terminals Page roundtrips Latency High amount of data transferred over and over again High server side resource consumption
- With Ajax Background, asynchronous communication With DHTML Application runtime platform Easy, really VERY *easy* deployment
- GWT application are standalone rich client applications running in the browser Can use RPC to fetch/ send data to the server, as rich clients do.
- No eye candy out of the box
- Use your favorite Java IDE to write and debug an application in the Java language, using as many (or as few) GWT libraries as you find useful.

- GWT provides performance twirks that would be hard to do by hand Image bundles Ressource bundles (sandbox) RPC optimization Code optimization Remove unused code Code compression/ obfuscation
- - DOM Abstraktion - Json, HTTP, HTML API - Browser History API - Unified event modell
- - obfuscation - code inlining - generate per browser per language permutationen (minimal code per instance)
- GWT defines coarse grained components called modules Young (huge, active) community developing many modules Logging, drag and drop, UI components, etc… Write your own UI-Components By composition By using JSNI By working with the DOM
- GWT provides a simple and powerful RPC framework Server side is backed by servlets Code gets optimized by the compiler Sends serializable Java objects over the wire (between browser and server) Simple integration to Java backends

- GWT Can Do What?!?! A Preview of Google Web Toolkit 2.0 Google Web Toolkit Track - Bruce Johnson One of the nicest things about working on an open source project is the atmosphere of community collaboration and brainstorming that it fosters. The GWT engineering team has been listening hard to the community about how GWT can be improved, and we're excited to take you on a tour of the powerful new features that have resulted. GWT 2.0 contains huge improvements, including dynamic script loading, a new catalog of compiler optimizations, and a new approach to hosted mode debugging that promises to revolutionize your productivity. Without a doubt, it will change the way you use GWT. http://code.google.com/events/io/2009/sessions/GwtPreviewGoogleWebToolkit2.html
