RE: calling extension java functions. ( Saxon Vs Xalan

The way I call extension functions in Saxon is:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
		    xmlns:str-utils="java:com.myutils.utils.StringUtils">

<xsl:value-of select="str-utils:upperCase($mystring)"/>

Somewhere in the documentation you can find: 

The SAXON namespace URI "http://icl.com/saxon" is recognised as a special
case, and causes the function to be loaded from the class
com.icl.saxon.functions.Extensions. This class name can be specified
explicitly if you prefer.

So I think you shouldn't refer to the SAXON namespace. Probably it looks in
the Extensions class for this method, and of-course it doesn't exist in this
class.

Hope this helps.

Kind regards,
Ismaël

Subject:  calling extension java functions. ( Saxon Vs Xalan)


I have a java extension method that i call from my XSL
the way i call is
<xsl:value-of select="str-utils:upperCase($mystring)"/>
it works fine with Xalan but fails with Saxon.
saxon gives
 Transform failed:  At xsl:value-of on line 264 of
file:/tests/saxon-test.xsl: No method matching upperCase with 1 parameter
found in class com.myutils.util.StringUtils

the namespace declaration is:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:saxon="http://icl.com/saxon" xmlns:str-utils =
"com.myutils.utils.StringUtils"
                extension-element-prefixes="saxon str-utils"  version="1.0">
It however doesnt give any error with the Xalan ( with a different namespace
declaration)
Am i calling it correctly?? is there any difference in the way you call
extension functions with xalan and saxon?
Thanks
