DOCBOOK: docbook.xsl VS chunk.xsl (xalan problems!)

Hi,
   I've been using docbook lately for writing some notes and
I really want to get them into multiple files rather than one
single cumbersome file.  Anyway, I tried using chunk.xsl
instead of docbook.xsl (which was working fine!) by entering
the xalan directory and typing:

java -cp
bin/xalan.jar;bin/xercesImpl.jar;bin/runtime.jar;bin/xsltc.jar;bin/xml-apis.
jar org.apache.xalan.xslt.Process -IN D:\EE557\notes\EE557.xml -PARAM
xalan.extensions 1 -XSL ../dbookxsl/html/chunk.xsl -OUT
D:\EE557\notes\index.html

However, using chunk.xsl I now get back:
(Location of error unknown)XSLT Error
(javax.xml.transform.TransformerConfigurationException):
java.xml.transform.TransformerException:
java.lang.ArrayIndexOutOfBoundsException

Could anyone please clarify to me what is going on please?  And if possible
a suggestion as to how to fix it please!
Thanks in advance,

David Molloy
