[George M. Coles]

Thanks.

Now I have corrected that. Still no change - the DataSource retrieved is
null.

The <ResourceParams> element should *not* be nested inside the <Resource>
element.  Instead, it should *follow* <Resource> at the same level.

    <Context path="..." ...>
      <Resource name="..." .../>
      <ResourceParams name="...">
        ... parameter elements ...
      </ResourceParams>
    </Context>
