Subject Xalan Java Extensions and Cocoon
Date Fri, 28 Mar 2003 17:05:34 GMT

I am new to Cocoon and Xalan. I am trying to use the Xalan extensions so that I can write
Javascript programs within XSL and tranform them into html using Cocoon.

I am trying the example given in http://xml.apache.org/xalan-j/extensions.html

This does not work with Cocoon. 

XML Source Document:

 <?xml version="1.0"?>
<doc>
  <name first="David" last="Marston"/>
  <name first="David" last="Bertoni"/>
  <name first="Donald" last="Leslie"/>
  <name first="Emily" last="Farmer"/>
  <name first="Jack" last="Donohue"/>
  <name first="Myriam" last="Midy"/>
  <name first="Paul" last="Dick"/>
  <name first="Robert" last="Weir"/>
  <name first="Scott" last="Boag"/>
  <name first="Shane" last="Curcuru"/>
</doc>
 

XSL for transforming is:

<?xml version="1.0"?> 
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:xalan="http://xml.apache.org/xalan"
                xmlns:counter="MyCounter"
                extension-element-prefixes="counter"
                version="1.0">

  <xalan:component prefix="counter"
                   elements="init incr" functions="read">
    <xalan:script lang="javascript">
      var counters = new Array();

      function init (xslproc, elem) {
        name = elem.getAttribute ("name");
        value = parseInt(elem.getAttribute ("value"));
        counters[name] = value;
        return null;
      }

      function read (name) {
        // Return a string.
        return "" + (counters[name]);
      }

      function incr (xslproc, elem)
      {
        name = elem.getAttribute ("name");
        counters[name]++;
        return null;
      }
    </xalan:script>
  </xalan:component>

  <xsl:template match="/">
    <HTML>
      <H1>Names in alphatebical order</H1>
      <counter:init name="index" value="1"/>
      <xsl:for-each select="doc/name">
        <xsl:sort select="@last"/>
        <xsl:sort select="@first"/>
        <p>
        <xsl:text>[</xsl:text>
        <xsl:value-of select="counter:read('index')"/>
        <xsl:text>]. </xsl:text>
        <xsl:value-of select="@last"/>
        <xsl:text>, </xsl:text>
        <xsl:value-of select="@first"/>
        </p>
        <counter:incr name="index"/>
      </xsl:for-each>
    </HTML>
  </xsl:template>
 
</xsl:stylesheet>

The Sitemap Configuration is:

      <map:match pattern="xalaneg.html">
      
        <map:generate type="file" src="content/xmlsrcdoc.xml" />
        <map:transform type="xslt" src="style/xalan.xsl" />                       
         
        <map:serialize type="html" />
        
        
      </map:match>

I have bsf.jar, js.jar and jsstyle.jar in WEB-INF\lib of cocoon and also in the server classpath.

Environment:

OS: Windows XP

App Server: Weblogic 7.0 (SP1)

JDK: JDK1.3.1

Cocoon version: Cocoon 2.0.4

The HTML output I get is:
Names in alphatebical order
[

What have I missed here?

Thanks.
