Hi Ana Belen
I quite often see this when there is some exception in the setUp phase that
isn't caught and printed out. The result is that scaDomain remains null and
hence JUnit calls tearDown() and calling scaDomain.close() causes a null
pointer exception. Try putting a try/catch around the code in setUp and
print out any exceptions that are thrown.
Hope that helps
Simon
