Managed to sort the classpath/loading issue and have got a stage
further.

The external class now loads OK but I think my xslt is wrong somewhere?

Any guidance would much appreciated!

XML:

<dataelements>
    <dataelement>
        <data>New York</data>
    </dataelement>
    <dataelement>
        <data>Boston</data>
     </dataelement>
     <dataelement>
        <data>Denver</data>
     </dataelement>
</dataelements>

XSLT:

<?xml version="1.0" ?>
<xsl:stylesheet version="2.0"
      xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
      xmlns:PGP="iPGP.iPGP"
      exclude-result-prefixes="PGP">

<xsl:template match="dataelements">
   <xsl:value-of select="PGP:setArmor(true()),
    PGP:setConventional(true()),
    PGP:setInputIsText(true()),
    PGP:setOutputIsText(true())"/>

   <xsl:param name="passphrase">mypswd</xsl:param>
   <xsl:param name="asciiresult"></xsl:param>
   <xsl:param name="errormessage"></xsl:param>

   <xsl:variable name="datain" select="data"/>
   <xsl:variable name="encryptData" select="PGP:encrypt($passphrase,
$datain, $asciiresult, $errormessage)"/>
   <xsl:value-of select="$encryptData"/>
</xsl:template>
</xsl:stylesheet>
