Cannot compile or run the sample

[GoogleCodeExporter]

I spent half a day on this and still am not able to get this sample compiled or 
run. I'm not very familiar with Maven and I'm stuck when the instructions don't 
work.

What steps will reproduce the problem?
1. Follow the steps for running GWT samples:
http://code.google.com/p/gwt-platform/wiki/RunningGwtpSamples
2. Try compiling and running from the command prompt.
3. Try compiling and running from eclipse.

What is the expected output? What do you see instead?
I see error message when compiling. (Please see attachments)

What version of the product are you using? On what operating system?
Revision 20 in the Hg repository.
Windows 7 x64

Please provide any additional information below.

It looks like this sample is old now and does not follow the current best 
practices. It is using some deprecated APIs such as RequestFactory and even the 
online demo at gwtgae2011.appspot.com does not seem to work (how do you save a 
new sketch?!) and does not work in all browsers (i.e. Internet Explorer). This 
can be a very useful sample for learning GWTP. I would appreciate if you update 
the sample and add some more documentation to it. Thank you.
