Looks like you should be requesting /filename/filename.htm instead of
filename/ ... that is unless you've set a welcome file in the app's
web.xml file.

If that doesn't work, also take a look at the tomcat logs for the moment
in time you a. started tomcat, b. deployed your app (if different from
the time tomcat was started) and c. when you requested the file.
