Re.[xsl] calling extension java functions. ( Saxon Vs Xalan)

["Laura" <xsl_list@xxxxxxxxxxx>]

 Thanks Dave and Cams..
 I did the stuff and had it running with Xalan..and everything is fine with
 XALAN. Fails with Saxon. The saxon.jar and the str-utils.jar( this contains
 my specific java stuff) are in classpath. The following is the Dos Result
 Screen

 D:\tests>java org.apache.xalan.xslt.Process -IN str.xml -XSL str.xsl -OUT
 RED
 BLUE
 BLACK
 GREEN
 ---------------------------------------------------------------------------
----------------------------
 With Saxon:

 Transform failed:  At xsl:value-of on line 18 of file:/D:/tests/str.xsl: No
 method matching upperCase with 1 parameter found in class
 com.myutils.utils.StringUtils

 This was just to test the extension functions in saxon. I know I could have
 used translate() method  to get the uppercase. But this is kind of a test
to
 get the Java thing running with Saxon.
 The bit that calls the extension element:
 <xsl:value-of select="str-utils:upperCase($colors)"/>

 and the namespace is:
 <xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
 xmlns:str-utils = "com.myutils.utils.StringUtils"
 extension-element-prefixes ="str-utils">

 I cant understand why this  fails  with Saxon

 thanks
