java.io.FileNotFoundException at org.apache.naming.resources.DirContextURLConnection.getInputStream

Question

I am working with JSF 2.0, tomcat 7.0, eclipse 3.0. Until a couple days ago, my web application was doing fine. When I started it up and tried to login, the servlet throws this error:

SEVERE: Servlet.service() for servlet [Faces Servlet] in context with path [/app] threw exception

I have no idea what file it is looking for. Any ideas on how to debug this? Thanks.

Answer 1

I've found a few similar posts and they both seem to point to config issues in your web.xml.

I would start there with debugging it.

Answer 2

Nevermind, found it by painstakingly going through every file association. Turns out the template file called by a UI file was missing. If there is a better way of finding such missing files I would love to know. Thanks.
