I've written some classes which I'd like to use to provide input to some XSLT transformations.  While I can use XSLT
namespaces to call methods in tjee SDK's java.* or even included libraries such as JAXB, I do not seem to be able to
create new instances of objects in jars I've created myself and added to my project's libraray.  

Attempts to apply the transform by right clicking on the xsl and xml files in the Projects window and selecting XML
transformation fail.  Attempting to validate the XSLT also fails with a message saying that it cannot find the class I'm
referring to.

My XSLT looks like:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
                xmlns:ws='http://www.kitfox.com/schema/puzzle'
                xmlns:java="java"
                xmlns:puz="com.kitfox.puzzle"
                version="1.0">
    
    <xsl:output method="xml" media-type="text/svg" indent="yes"/>
    
    <xsl:template match="ws:puzzle">
        <svg:svg>
            <xsl:attribute name="date">
                <xsl:value-of select="java:util.Date.new()"/>
            </xsl:attribute>
            
            <xsl:attribute name="myAttr">
                <xsl:value-of select="puz:SimpleObj.new()"/>
            </xsl:attribute>


the error message I get when validating is below.  I am certain this class exists in this package in the jar in my library:
