[jdom-interest] malformed URL exception exception in saxbuilder.build due to unreachable URL

[Oliver Ruebenacker]

     Hello,

  I would guess the fact that a piece of XML content appears where a
URL is expected points to some kind of coding error. Can you post a
few lines of your code?

     Take care
     Oliver
