Xalan issue in Cocoon java-util.EmptyStackException

[John Austin <jw...@sympatico.ca>]

I posted the following  on the Cocoon-users list and was directed
to this list as one of the local experts (J. Pietschmann) felt the
issue might be a recurrance of an old Xalan problem.

Does this item ring a bell here ?



Just started playing with Cocoon again after striking out
with it about a year ago. The product is MUCH improved.


I have just installed Cocoon 2.1.2 on my RedHat 9 system and
am attempting to generate RTF from a DocBook file.

1) RH 9 2.4.20-20.9
2) JAVA_HOME: /opt/j2sdk_nb/j2sdk1.4.2
3) Cocoon: 2.1.2; simple build and invoked as ./cocoon.sh servlet
    so it runs Jetty and services port 8888
4) The XML file(s) I use all produce RTF output when I use
    the Linux scripts docbook2pdf, docbook2html and docbook2rtf
5) Cocoon successfully generates PDF, HTML and apparently
    produces PS and other outputs (My browsers have no PS helper 
    applications)
6) Cocoon chokes when I ask it to produce RTF output.

Question 1: 

What should I do ?

Question 2:

Has this got anything to do with versions of Xerces and Xalan shipped
with the SDK 1.4.2 ? I followed the instructions on the Cocoon site
about copying the newer versions into jre/lib/endorsed directory but
there was no improvement. See output of EnvironmentCheck following
