Yes, but I *MAY* have a web.xml for JUnit testing only and it has
minimal configuration just to get the REST stuff to fire up and it
will not be shipped in the REST module, REST Web module will have its
own web.xml. Another point to adding a web.xml to JUnit test is, IMHO,
I would also like my web.xml to be part of the test just to ensure
that it works as expected as well. Also one could take the approach
mentioned by Paul Sandoz as well. IMO, it depends on the approach you
take.
