GWT 2.1.RC1 Expenses Sample Failure

The sample fails on the server-side because
somehow the EMF does not get initialized.

I've imported the sample into Eclipse 3.6 on
Windows 7 and running the LoadExpensesDB
module via Debug As menu item of Eclipse
Property Context Menu.

Can anybody please shed some light on how to
initialize the server-side DB and services?

The exception is:
[ERROR] javax.servlet.ServletContext log:
Exception while dispatching incoming RPC call
com.google.gwt.user.server.rpc.UnexpectedException:
Service method 'public abstract java.util.List
com.google.gwt.sample.expenses.client.DataGenerationService.getCounts()'
threw an unexpected exception: java.lang.ExceptionInInitializerError
