It is likely that you are using the old Xalan release packaged in JDK 1.4.
Please read this FAQ (http://xml.apache.org/xalan-j/faq.html#faq-N100CB) on
how to use Xalan with JDK 1.4.

I can't get the math:abs() or any other EXSLT function to rock. I'm
hitting the java.lang.NoSuchMethodException every time.
The shell dump below should give all the details:
