Newbie: resolveEntity always passes null arguments

[Hugo Ferreira <hm...@inescporto.pt>]

Hi,

I have recently downloaded the Xalan library and have encountered a small
yet
difficult problem. I have based my class on the Dom2Dom example. I changed
this example to pass a stream instead of a file name. When I parse the xml
file,
the DTD entity is not found (if no DOCTYPE is used in the XML file, all is
ok).
After searching the archives I implemented an EntityResolver class.

This class is used by the parser after I do a:

         DTDResolver er = new DTDResolver( "xsl" );
         DocumentBuilder  ...
        dBuilder.setEntityResolver( er );

When executing the class, the callback method is invoked, but the
parameters are always null.

Can anyone tell me if in fact this is a known problem/feature or
if I am attempting to do the impossible.

TIA.
Hugo Ferreira.
