"...in case a document author (human or not) created a document with a particular schema in view, and warrants that some or all of the document conforms to that schema, the schemaLocation and noNamespaceSchemaLocation [attributes] (in the XML Schema instance namespace, that is, http://www.w3.org/2001/XMLSchema-instance) (hereafter xsi:schemaLocation and xsi:noNamespaceSchemaLocation) are provided. The first records the author's warrant with pairs of URI references (one for the namespace name, and one for a hint as to the location of a schema document defining names for that namespace name). The second similarly provides a URI reference as a hint as to the location of a schema document with no targetNamespace [attribute]."
Left unsaid is the fact that lists in XML are whitespace-separated.

Didn't notice the slash when cut and pasting. Should be, e.g.,
String location = "http://www.xyz.net/oagis file:///D:/ASAP/Test/Test/xyz/Origination/Standalone/GetLoan.xsd";

Looks like a different problem. I'm pretty sure you need to specify a namespace, URI pair in a schemaLocation, like you did in your document.
E.g.,
String location =
"http://www.xyz.net/oagis file://D:/ASAP/Test/Test/xyz/Origination/Standalone/GetLoan.xsd";

I'm trying to achieve the same thing. It doesn't seem to work for me too. XML document looks like:

From the trace it seems like the *external-schemaLocation* propertyis not
being used. The other question that I had was that, the 'GetLoan.xsd' schema
refers to umpteen other schemas through <include>s and <import>s. Should the
*external-schemaLocation* property include a comma separated list of the
file URLs for ALL the schema documents referred to directly or indirectly ?

What you have specified as an argument is pretty clearly not a URI. It doesn't begin with a scheme. It's hard to tell from reading it what the correct URL should be, but the form must be:
jar:file:/path-to-jar-file!/path-within-jar-file
Just guessing, yours would be:
jar:file:/home/peter/.dpml/main/dpml/test/jars/dpml-test-testschema.jar!/net
/dpml/test/testschema/ConfigurableB.xschema
What did you think the
/home/peter/metro/svn/development/main/metro/composition/test/
at the beginning would accomplish?

Hi,
trying to set the feature on a 2.6.2 SAXParser (validation enabled etc.):
m_parser.setErrorHandler(handler);
m_parser

m_parser.parse( new InputSource( new ByteArrayInputStream( xml

with a path to the schema that sits inside a .jar file it seems that the schema is not found, since I get an error saying that
the
root element cannot be found:
org.xml.sax.SAXParseException: cvc-elt.1: Cannot find the declaration of element 'configuration'.
What kind of schema location is supported by the feature?
Thanks for help
