I'm not surprised. Your EntityResolver is unconditionally returning the
same InputSource regardless of the parameters passed to resolveEntity().
Looks like your EntityResolver would be called at least twice; once for the
external DTD ("?mpboe03.dtd") and once for the "isobox" parameter entity (
"http://www.w3.org/2003/entities/2007/isobox.ent";). You should examine the
systemId / publicId in your decision making of what to return from the
method.
Thanks.
