Newbie questions: How do I get to EXSLT functionality in XALAN?

Two questions:

1) I'm using xalan-j_2_5_D1 on Win2K

I am trying to use the EXSLT functions - the str XSL functions in
particular. I am not having much luck with XALAN
recognizing any of the "exsl:xyz" or "str:xyz" references

After reading the doc on Extensions and Extension Libraray, I have in my
CLASSPATH: xalan.jar; xml-apis.jar; xercesImpl.jar, bsf.jar (where is
js.jar, btw?). Do I need anything else in the my classpath? or anything in
some config area?

I wrote the xsl test script below.. The ONLY function that reports its
available is "xalan:nodeset". None of the other functions below are found.

This is probably something really silly I'm overlooking. Any help would be
appreciated.

2) Also, assuming I get past the above problem.. Reading through the xalan
EXSLT support docs, it appears that str:replace in particular is not yet
supported natively in xalan. I am planning on copying over
str.replace.template.xsl from the EXSLT str.zip to the dir containing my
other XSL scripts and importing it as follows.

<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:str="http://exslt.org/strings"
extension-element-prefixes="str">
<xsl:import href="str/functions/replace/str.replace.template.xsl" />

<<< Use the str:replace function here >>>

Is this the right way? Or is there a better approach? Thx.

Ashok
