IllegalStateException using javax.xml.parsers.DocumentBuilder.parse()

[steven.bagnall]

Hi,

Have a java application that attempts to create a DOM document from an
XML f
ile by validating against an XSD which is defined in the code. The
RuntimeE
xception, IllegalStateException is raised on the line:

document = builder.parse(new File(argv[0]));

If you validate the XML with the XSD using say an online validation
utility
it validates fine. I have posted the stack trace, and the Java file
below.

Thanks in advance.

Steve.
