Bug in parser? 2003-05-24 - By Michael Rafael Glavassevich
Hi Jon,
It would be great if you posted a snippet of code before and including
the invocation of SAXBuilder.build, in order to diagnose your problem. It
seems that there is something wrong with the location specified for your
XML file (either an invalid URI, or java.net.URL doesn't recognize the
protocol/scheme of the URI). In either case, Xerces is unable to read
your file.
As a separate issue, I noticed that the system ID that you specified for
your DTD is not a valid URI. It should be
"file:///C:/temp/projects/EventRegistrations.dtd" instead of
"file:///C:\temp\projects\EventRegistrations.dtd" ('\' isn't a valid URI
character). Xerces (by default) will fix up the system ID before it's
used. However, if you want your documents to be portable across different
XML parsers, then you need to make sure that URIs you specify actually
meet the URI spec.
Hope that helps.
