!! Move from GWT to GXT

!! Create the GWT project

* Create Eclipse project with GWT's @@webAppCreator@@ shell command (e.g. @@webAppCreator -out subdir com.example.myapp.MyApp@@)
* Import project into workspace (File -> Import... -> Existing Project into Workspace etc.)
* Remove the GWT jar files from the project
* Add the GWT and GXT user libraries (see [[Set up Eclipse for GWT and GXT]]) to the project

!! Movie from GWT to GXT

!!! Adapt the GWT module
* Open @@src/com.example.myapp.MyApp.gwt.xml@@
* Comment out the line @@<inherits name='com.google.gwt.user.User'/>@@ (and potentially others)
* Insert the line @@<inherits name='com.extjs.gxt.ui.GXT'/>@@

!!! Copy GXT resources (the style) to your project

* Create directory @@war/gxt@@
* Copy @@/path/to/gxt/resources/*@@ to the Eclipse project's @@war/gxt@@ folder (i.e. there must be a file at @@war/gxt/css/gxt-all.css@@ now)


!!! Adapt the hosting HTML file
* Open @@war/MyApp.html@@
* Find the section in the HTML file's @@head@@ part, where the CSS files are linked in (search for @@.css@@ in the file)
* Add a reference to the GXT styles (@@<link rel="stylesheet" type="text/css" href="gxt/css/gxt-all.css" />@@)

!! Optional part: Drop non-GUI parts

In case this application will consist of a GUI only, you can get rid of the server specific parts. To remove the non-GUI parts from the Eclipse project do this:

* remove the @@com.example.myapp.server@@ and @@com.example.myapp.shared@@ packages
* remove @@war/lib/gwt-servlet.jar@@
* edit the @@war/WEB-INF/web.xml@@ file and remove (or comment out) the @@servlet@@ and @@servlet-mapping@@ parts, so that only the default page section remains
