Thanks to the guys on the GWT forum for helping me solve this problem. It did turn out to be a classpath problem and there follows an explanation of the steps I took to discover the issue and how I solved it:
To find out the classpath used: In Eclipse select Debug view by going to "Window|Open Perspective|Debug" and then select the debug window by going to "Window|Show View|Debug" then right click the last item in the list shown and select "properties" I found that my appengine SDK path was being references about 21 times as: C:\Program Files\eclipse\plugins \com.google.appengine.eclipse.sdkbundle. 1.3.2_1.3.2.v201003241245\appengine-java-sdk-1.3.2 so I copied it to "C:\appengine-java-sdk-1.3.2" And then linked to it by doing the following: In Eclipse select the Java view by going to "Window|Open Perspective| Java" and then select the project properties by going to "Project| Properties" then select "Google|App Engine" and click on "Configure SDK's" then click "Add" on the right hand side and select the path you just created eg "C:\appengine-java-sdk-1.3.2" and add a "Display Name" eg "Short App Engine SDK". Click OK as needed to close all the windows, and everything should start working again!!!
