Using JAR files

[Michael Day]

Hi,

I have a servlet that requires classes from xalan.jar. I've tried placing
this JAR file in TOMCAT_HOME/lib, WEB-INF/lib, in the CLASSPATH and
nothing seems to work. When the servlet runs it invariably fails with a
NoClassDefFound exception when it tries to access
org.apache.xpath.XPathAPI.

Any advice on how to get tomcat to see JAR files required by a servlet?
Thanks,

Michael
