[jdom-interest] EntityResolver (DTD Not Found)

[Szegedi, Attila]

Right. The solution suggested originally is wrong. When an EntityResolver
returns null from resolveEntity, it means "I have no clue about this entity,
you (the parser) try looking it up however you can" -- which usually means
the parser will try interpreting the system id as an URL or a file, then
give up. If you really want to provide an empty entity, you could try
returning

  new InputSource(new StringReader(""))

instead of null.
