How can I refer to XSD with CLASSPATH to validate my XML?

As part of my XML transformation (using XSL), I create an attribute for the layout of the schema so that the result of the transformation can be verified. However, since I am trying to run this as a standalone test, I want to be able to set the appropriate attribute / value for the location of the schema from my CLASSPATH.

After a bit of googling, I tried various schemaLocation attributes, the last attempt:

.. <xsl:attribute name="xsi:external-noNamespaceSchemaLocation"> <xsl:value-of select="$schemaLocation"/> </xsl:attribute> ..

What after conversion leads to:

 <?xml version="1.0" encoding="UTF-8"?> <emrException xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:external-noNamespaceSchemaLocation="emrException_1_0.xsd"> .. <!-- more well-formed XML --> </emrException>

I double-checked that my emrException_1_0.xsd file is explicitly in CLASSPATH when starting authentication. This is a DOM validator, and I am using Xerces 2.9.1 / Xalan 2.7.1, the result of which is:

 Caused by: org.xml.sax.SAXParseException: cvc-elt.1: Cannot find the declaration of element 'emrException'.

However, when I switch to using a schema location where the XSD file is read from the file system or an external URL, then the validator works fun.

How can I get an XSD to read from my CLASSPATH?

One way is to implement your own LSResourceResolver and LSInput, so that the system identifier that is passed can be resolved, but you want to.
