Tomcat 3.2.1 bug if not root-context defined.

[Klaus Friedel]

Tomcat 3.2.1 fails to deliver a resource, if no root-context is defined in serverl.xml.
If you do not define the root-context "" in server.xml and request a non-existing 
resource,
Tomcat will loop forever in PrefixMapper.getLongestPrefixMatch() trying to find a 
Container for "".

Bye,
Klaus.
