Major New Features in the GWT SDK
- In-Browser Development Mode
- Prior to 2.0, GWT hosted mode provided a special-purpose „hosted browser“ to debug your GWT code. In 2.0, the web page being debugged is viewed within a regular-old browser. Development mode is supported through the use of a native-code plugin called the „Google Web Toolkit Developer Plugin“ for many popular browsers. In other words, you can use development mode directly from Safari, Firefox, IE, and Chrome.
- Developer-guided Code Splitting
- Code splitting using GWT.runAsync(), along with compile reports (also known as The Story of Your Compile) allows you to chunk your GWT code into multiple fragments for faster startup. Imagine having to download a whole movie before being able to watch it. Well, that’s what you have to do with most Ajax apps these days — download the whole thing before using it. With code splitting, you can arrange to load just the minimum script needed to get the application running and the user interacting, while the rest of the app is downloaded as needed.
- Declarative User Interfaces with UiBinder
- GWT’s UiBinder now allows you to create user interfaces mostly declaratively. Previously, widgets had to be created and assembled programmatically, requiring lots of code. Now, you can use XML to declare your UI, making the code more readable, easier to maintain, and faster to develop. The Mail sample has been updated to show a practical example of using UiBinder.
- Bundling of Resources via ClientBundle
- GWT introduced ImageBundle in 1.4 to provide automatic spriting of images. ClientBundle generalizes this technique, bringing the power of combining and optimizing resources into one download to things like text files, CSS, and XML. This means fewer network round trips, which in turn can decrease application latency — especially on mobile applications.
- Simplified Unit Testing with HtmlUnit
- Using HtmlUnit for running test cases based on GWTTestCase: Prior to 2.0, GWTTestCase relied on SWT and native code versions of actual browsers to run unit tests. As a result, running unit tests required starting an actual browser. As of 2.0, GWTTestCase no longer uses SWT or native code. Instead, it uses HtmlUnit as the built-in browser. Because HtmlUnit is written entirely in the Java language, there is no longer any native code involved in typical test-driven development. Debugging GWT Tests in development mode can be done entirely in a Java debugger.
Major New Features in the Google Plugin for Eclipse
- Development Mode Launch View
- Integrates your Development Mode logs right into Eclipse, which means one less window to shuffle around
- UiBinder Support
- The UiBinder template editor provides auto-completion and formatting for editing ui.xml files (and embedded CSS blocks)
Validation of UiBinder templates and backing Java classes
New UiBinder wizard to quickly get started- ClientBundle Support
- „New ClientBundle“ wizard to bundle CSS and other resources together to minimize HTTP round-trips
As-you-type validation ensures that your app’s static resources are always in the right place- RPC Refactoring
- Automatically updates sync/async pairs of RPC interfaces and their methods
- JNSI Reference Auto-completion
- Auto-completion takes the pain out of referencing Java members from JSNI methods
Das wäre ein grund von NetBeans zu Eclipse zurück zu kehren. Oder gibt es ähnlich gute GWT-Plugins für NB?
