Customize Eclipse to work with Ext - GWT

Google Web Toolkit (GWT) is a set of AJAX components for developing user interfaces for web 2.0 applications. This library should be familiar to us from GMail, Google Reader and many other projects. A distinctive feature of this framework is that programs can be written in Java. Ext-GWT (or GXT) is an extension of GWT using the popular ExtJS web UI library.

Attention
GXT beta 2 requires GWT 1.5 milestone 2, which supports J2SE 6.0. Download links in the Resources section.

Setting the variable GWT_HOME

It is done for each of the developers once:
')
1. In the Eclipse main menu, we find the management of the Classpath Variables. To do this, go to: Menu - Window - Preferences - Java - Build Path - Classpath Variables;
2. Create a variable GWT_HOME. New button:
* specify the name. Name: GWT_HOME;
* Specify your path to the GWT root folder, for example “D: \ Projects \ gwt-windows-1.4.62 \” like mine.

Creating a new project on GWT

1. We use standard utilities to create a project:
* projectCreator -eclipse NewApplication -out d: \ Projects \ NewApp
* applicationCreator -eclipse NewApplication-out d: \ Projects \ NewApp com.brainitup.client.NewApplication
2. Import the created project in Eclipse. To do this, go to Menu - File - Import - Existing Projects into Workspace. Specify where the project is, for example “d: \ Projects \ NewApp”
3. Configure the gwt-user library via GWT_HOME:
* right click on project root - Properties - Java Build Path - Libraries
* delete gwt-user.jar
* Add Variable - GWT_HOME - Extend - gwt_user.jar - Ok
4. Configure the gwt-dev-windows.jar library via GWT_HOME:
* Run - Java Application - NewApplication (your name) - Classpath
* gwt-dev-windows.jar - Remove
* Advanced - Add Classpath Variables - GWT_HOME - Extend - gwt-dev-windows.jar - Ok

Cyrillic characters support

1. Project Properties -> Resources -> Text File encoding install UTF-8
2. In the Package Explorer, we find the file NewApplication-> src-> com.brainitup-> public-> NewApp.html and we prescribe the tag meta tag
/>

Add Ext - GWT

1. Set up the GXT_HOME variable in the same way as with GWT_HOME
2. Set up the gxt library through the GXT_HOME variable (similar to the one described above) and also do not forget to add it as a library for launching (similar to section 4 of the section “Creating a project on GWT”)
3. Add the following line to the project xml module

4. Add a style file to your host page.
