hi!

i'm using cocoon (http://xml.apache.org/cocoon) to publish
xml-documents as html. i was trying to use the docbook format, but
for some reason, i am unable to get the stylesheets to work correctly
on my machine.

the versions i'm using:

docbook-xml 4.2
docbook-xsl 1.53.0 
xerces 2.0
xalan 2.3.1
jdk 1.4
operating system: windows2000

the xml-file i'm using is validated against the DTD, and still cocoon
(which uses xalan) throws an error. i tried the same with the
xslt-plugin for jedit (which uses xerces), and it also returns an
error.

specifically, jedit gives the following error:

java.lang.RuntimeException: 5 >= 1

xslt.XSLTUtilities.transform(XSLTUtilities.java:83)
xslt.XSLTProcessor$6.actionPerformed(XSLTProcessor.java:313)

cocoon is a bit more detailed:

i've snipped most of the stacktrace.

what could be the cause of this error? i'm really stuck, because the
error seems to occur in one of the docbook-stylesheets?

i'm sorry if this question was already covered, but i didn't find
anything in the mailing list archive or on the web.

thanks,

rick
