I want to know how to call Java methods from XSLT - I think it has to look like this:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:counter="de.mycompany.mypackage.myClass>

<xsl:value-of select="counter:myMethod('Paramter1',string(Paramter2))"/-->

But i get alway the Exception

Call to extension function failed: de.mycompany.mypackage.myClass
I also set the Classpath.
what do i wrong ?
Thx again,
Holger

Holger,
I wish it was that simple, but I learnt it isn't

You will have to make use of XSLT Java extensions. Here is the example from apache website, of XSL that uses XSLT extensions.

<?xml version="1.0"?> 
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

                xmlns:lxslt="http://xml.apache.org/xslt"
                xmlns:counter="MyCounter"
                extension-element-prefixes="counter"
                version="1.0">

<lxslt:component prefix="counter"
                   elements="init incr" functions="read">
    <lxslt:script lang="javaclass" src="MyCounter"/>
  </lxslt:component>
  <xsl:template match="/">
    <HTML>
      <H1>Names in alphabetical order</H1>
      <counter:init name="index" value="1"/>
      <xsl:for-each select="doc/name">
        <xsl:sort select="@first"/>
        <p>
        <xsl:text>[</xsl:text>

        <xsl:value-of select="counter:read('index')"/>

        <xsl:text>, </xsl:text>
        <xsl:value-of select="@first"/>
        </p>
        <counter:incr name="index"/>
      </xsl:for-each>
    </HTML>
  </xsl:template>
 
</xsl:stylesheet>

Ofcourse, if you find an easier way, please share with us !

I didn't like the taste of tongue and it didn't like the taste of me. I will now try this tiny ad:
