Dear Francis,
(Paraphrasing from a previous answer on essentially the same question:)
The problem is that since using an Input"Stream"Source you have provided
no way for the parser to determine where to resolve paths to the
resource you are parsing, it only has this stream of bytes, no origin.
So, if you want to use an InputSource, you should set the system id on
the
inputsource:
is.setSystemId("../testresolve.xml");
so Xerces knows where to look for the DTD relative to.
Kind regards,
--Sander.
