RE: Specifying a DTD file when parsing XML files that don't contain !DOCTYPE lines

[Mike O'Leary]

Will,

When I try this, I get an error that says:

 

javax.xml.parsers.ParserConfigurationException: jaxp_feature_not_supported:
Feature "http://xml.org/sax/features/use-entity-resolver2"; is not supported.

What am I doing wrong?

Mike

One more note about a bug I found in this code. It only works once. When you
parse a second document, you get an exception because the FileReader for the
DTD has already been closed.
