Yes, I wrote a servlet that uses Xalan-Java. You're in for a ride,
depending on the version of Tomcat you're using.
(1) if you're willing to use the same parser that Tomcat uses (ProjectX
or Crimson for Tomcat 3.x and 4.x respectively), you can just put
xalan.jar in the CLASSPATH.
(2) if you need to use Xerces, or if you need to use Xalan 2 (which
comes with a modified copy of JAXP):
(a) if you're under Tomcat 4.0 AND if you're not using JSP,
delete crimson.jar from the lib directory. Otherwise the
version of JAXP 1.1 included will conflict and cause a
"Sealing violation" SecurityException. This is due to the
way Sun packaged it--it chokes if a ClassLoader attempts
to load one of those "sealed" packages from another JAR
(b) if you're under Tomcat 3.x, I think you actually have
to replace the parser Tomcat uses with Xerces, because
otherwise you'll get a MissingMethodError (the XML parser
shipping with Tomcat 3.x has an older version of the DOM
without namespace support).
I don't know what you can do if you're on Catalina AND you need to keep
using Jasper--I'd be interested in the answer myself....
