[jdom-interest] JDOM and XML Schema

[Richard Baldwin]

Two related questions:

1.  It seems necessary to invoke new SAXBuilder(true)
to turn validation on with JDom.  What is the purpose
of the method in the SAXBuilder class named
setValidation(boolean validate)?  It doesn't seem to do
anything.

2.  I can validate the following XML file named
Schema001.xml against the schema file named
Schema001.xsd using a validator derived from xerces
1.3.0 (based on validate.bat in example01 from Roger L.
Costello's, XML Schema Tutorial at
http://www.w3.org/XML/Schema).  I know that validation
is working, because I can corrupt the XML file and
cause validation errors.

When I try to process Schema001.xml with a simple
printing program written using JDOM, I get a screen
full of validation errors, complaining about
http://www.somedummyurl


File Schema001.xml
<?xml version="1.0"?>
<book xmlns="http://www.somedummyurl"
xmlns:xsi="http://www.w3.org/2000/10/XMLSchema-instance"
xsi:schemaLocation=
"http://www.somedummyurl Schema001.xsd">
This is a string
</book>



File Schema001.xsd
<?xml version="1.0"?>
<xsd:schema
xmlns:xsd="http://www.w3.org/2000/10/XMLSchema"
targetNamespace="http://www.somedummyurl"
xmlns="http://www.somedummyurl"
elementFormDefault="qualified">
<xsd:element name="book" type="xsd:string"/>
</xsd:schema>


What am I doing wrong?
Thanks,
Dick Baldwin
