If you are like me and use Eclipse to develope your GWT application there is a nice change that is part of this release. You no longer need to run these commands to create a new GWT Eclipse project:

C:\Program Files\gwt-windows-1.5.3>applicationCreator.cmd -eclipse MyGWTProject -out c:\MyGWTProject com.mynumnum.client.MyClass
Created directory c:\MyGWTProject\src
Created directory c:\MyGWTProject\src\com\mynumnum
Created directory c:\MyGWTProject\src\com\mynumnum\client
Created directory c:\MyGWTProject\src\com\mynumnum\public
Created file c:\MyGWTProject\src\com\mynumnum\MyClass.gwt.xml
Created file c:\MyGWTProject\src\com\mynumnum\public\MyClass.html
Created file c:\MyGWTProject\src\com\mynumnum\public\MyClass.css
Created file c:\MyGWTProject\src\com\mynumnum\client\MyClass.java

C:\Program Files\gwt-windows-1.5.3>projectCreator.cmd -eclipse MyGWTProject -out c:\MyGWTProject

Created directory c:\MyGWTProject\test
Created file c:\MyGWTProject\.project
Created file c:\MyGWTProject\.classpath

Now all you need to do is run the command webAppCreator:

C:\Program Files\gwt-windows-1.6.0>webAppCreator.cmd -out c:\MyGWT16Project com.
mynumnum.MyClass
Created directory c:\MyGWT16Project\src

Created file c:\MyGWT16Project\MyClass.launch

Your new GWT 1.6 Project will be ready for import into Eclipse. Also you will notice that a simple client and server class is created in the example that demonstrates how to send and receive RPC requests.

Errors when launching your Eclipse GWT project in the GWT shell

You must create a lib folder in your 'project folder'/war/WEB-INF folder and copy gwt-servlet.jar into that folder.
After this is done you should be able to launch your new Project without this nasty error message:
