I am using tomcat 5.x and everything including the package is in the
web-inf directory. The mappings are correct to the best of my
knowledge......am i making a mistake somewhere or have i run into a
bug in the software? Is there any way to work around this problem? I
have been struggling with this problem for a long time and any help
would be greatly appreciated. I must also add that i am using JDOM in
my package to read an XML document. Could this be a problem with JDOM?

I never use JDOM, but generaly its WAR file should be in
your_app/WEB-INF/lib
or in /tomcat/common/lib
or in /tomcat/shared/lib.

I hope it helps.
