Hi,
Environment: Redhat Linux
Tomcat: Version 6.0

I'm getting exception like
javax.naming.NamingException: Resource 
/WEB-INF/classes/META-INF/services/com.sun.org.apache.xml.internal.dtm.DTMManager
 not found

javax.naming.NamingException: Resource 
/WEB-INF/classes/net/sourceforge/jtds/jdbc/Driver.class not found

in lookup method of org.apache.naming.resources.ProxyDirContext.

In my application this isn't causing a logic issue, but this bug is manifesting 
as a notable performance problem. Every time a bad path is passed into the 
ProxyDirContext it's actually causing quite a lot of NamingExceptions to be 
thrown as it tries alternative paths (see BaseDirContext.lookup). All of these 
exceptions are swallowed but what I'm seeing is that this is happening many 
times over the course of a request as my application is looking up different 
resources, and the time it takes to build all of these swallowed 
NamingExceptions has become significant.

The path where the tomcat tries to search the resource doesn't exists. I tried 
searching the configuration files in conf folder of Tomcat but nowhere this 
type  of path  is mentioned.
Any help/pointer on how tomcat figures out resource path will be of great help.

Thanks,
Rajeev.
