I'm making a simple call to get a parameter from the request. The underlying impl of Tomcat is throwing an NPE. A partial dump of the stacktrace is below.

I can't find the matchin source, but from what I can tell I'm thinking the org.apache.catalina.Context is null. Is there anything that would cause this object to not have a valid value?

Thanks in advance for any help.
