XALAN 2 - Using Java Extension Functions

[Morten Grue Nielsen]

Hi

I have made a Translate class, in which a replace method is found. This
method replace words, with other in a string. I have a problem trying to get
to this method by using xslt extension functions with xalan j_2_2_D14.
Instead of using the replace method in my Translate class, it uses the
replace method in the java.lang.String class. Can you help me ??

---------- The xslt script : -----------

xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
 xmlns:lxslt="http://xml.apache.org/xslt";
 xmlns:bdf="dk.bording.axt.tc.xsl.Translate"
 extension-element-prefixes="bdf"
 version="1.0">

 <lxslt:component prefix="bdf" functions="replace">
  <lxslt:script lang="javaclass"
src="xalan://dk.bording.axt.tc.xsl.Translate"/>
 </lxslt:component>

 <xsl:output indent="yes" method="xml" encoding="iso-8859-1"
cdata-section-elements="VALUE NAME KEY SOURCE pling"/>

 <xsl:template match="/">
  <xsl:apply-templates select="text()"/>
  <document>
   <pling>
    <xsl:for-each select="function/test">
     <xsl:value-of select="bdf:replace(string(text()),'asd','abc')"/>
    </xsl:for-each>
   </pling>
  </document>
 </xsl:template>
</xsl:stylesheet>
