RE: [xsl] Frustration High (Possible path problems?)

["Josh Canfield" <Josh.Canfield@xxxxxxxxxxxx>]

This is an xalan specific question, they have a mailing list here: http://xml.apache.org/mail.html

It's usually better to start simple to start tracking things down. Since you didn't include the stylesheet element I can't be sure, but I'm betting that you declared the java namespace incorrectly. 

The xsl below works, but if I change the xmlns:java to "frog" I get: 

java.lang.ClassNotFoundException: frog.java.lang.Math
        at java.net.URLClassLoader$1.run(URLClassLoader.java:195)
        at java.security.AccessController.doPrivileged(Native Method)


<?xml version="1.0" encoding="UTF-8"?>
 <xsl:stylesheet version="1.0" 
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; 
    xmlns:java="http://xml.apache.org/xalan/java";>
  <xsl:output method="xml" encoding="UTF-8" indent="yes"/>

  <xsl:template match="/">
    <three><xsl:value-of select="java:java.lang.Math.floor(3.14)"/></three>
  </xsl:template>

</xsl:stylesheet>

Extension functions depend on which processor you are using, so that's the
first thing you should tell us.

It's also possible of course that you aren't using the processor you think
you are...
