Stylesheet first won't compile under Java 1.5, then can't find function tokenize

OK, I had a stylesheet that was working fine in Java 1.4, but when I tried and compile it in 1.5 I was getting a FATAL ERROR: Cant' compile stylesheet.  So, I searched the net and found out that 1.5 is packaged with an old version of Java and that you need to override it by creating a directory called "endorsed" in the jre lib

see:
http://xml.apache.org/xalan-j/faq.html#faq-N100D6

SO ... I created C:\Program Files\Java\jdk1.5.0_05\jre\lib\endorsed
and put the following jars in it as it specifies (from Xalan 2.7)
serializer.jar
xalan.jar
xercesImpl.jar
xml-apis.jar

and now I'm getting the following error:
SystemId Unknown; Line #79; Column #61; Could not find function: tokenize
SystemId Unknown; Line #79; Column #61; function token not found.
(Location of error unknown)java.lang.NullPointerException
Error: java.lang.NullPointerException

So basically I'm at my wits end.  The stylesheet works fine when I am running it in Oxygen XML editor using Saxon 8B.

So I guess my question becomes, how do I make the program use Saxon 8B, or do you know of a way that I can fix this?

This is how i set up the transformer
                  Transformer transformer = TransformerFactory.newInstance().newTransformer();
                  transformer.setOutputProperty(OutputKeys.METHOD, "xml");
                  transformer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
                  transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "4");
                  transformer.setOutputProperty(OutputKeys.INDENT, "yes");
                  transformer.transform(source, result);
