[xsl] java servlet with xsl/xml transform. or java/xml listserv(xalan/tomcat)

[Robert Koberg <rob at koberg dot com>]

(using Xalan and Tomcat & my classpath is at the bottom of this post)

I don't know if this is the correct forum for this question (please point me
to the correct one?).  I am trying to use the servlet example from the
xml.apache.org and xalan2
(http://xml.apache.org/xalan-j/samples.html#servlet).  I am new to java, but
I have servlets working. I compile the source provided by the servlet
example and put it into the examples directory provided by tomcat (servlets
work there).  But when I try to hit the servlet I get:

Error: 500

Internal Servlet Error:

So that would seem to me to be a classpath problem but I am pretty sure I
have everything there:
