EXSLT problem - XalanJ 2.5.1

[Everett Stauffer <ev...@chem.ucsd.edu>]

Hi folks-

Maybe I'm missing something but I can't seem to get exslt functions
to work with XalanJ 2.5.1.

I've declared the namespace:
   xmlns:set="http://exslt.org/sets"

I'm trying to setup a nodelist with:
   <xsl:variable name="orgs" select="set:distinct(//ORG)"/>


I get the following error:
javax.servlet.ServletException: java.lang.NoSuchMethodException
For extension function, could not find method 
org.apache.xpath.axes.DescendantIterator.distinct([ExpressionContext,] ).

This is on Tomcat 3.2.3, with JDK 1.4.0.

Mind you, I've been using Xalan for a couple of years without any problems.


Just for kicks, I tried something even more brain-dead:

   xmlns:date="http://exslt.org/dates-and-times"

The following:
   <xsl:value-of select="date:dateTime()"/>
produces:
javax.servlet.ServletException: javax.xml.transform.TransformerException: 
Instance method call to method dateTime requires an Object instance as first 
argument

Which is pretty surprising considering that the API docs state:
static java.lang.String 	dateTime()
    The date:date-time function returns the current date and time as a
    date/time string.


Soooo, what am I missing in using EXSLT functions?


TIA,

Everett
