Tomcat 3.2b upgrade installation trouble

[Brad Johnson <br...@papermedia.com>]

I apologize in advance for the basic question.  
 
In moving from Tomcat 3.1 to 3.2b, I keep getting a 500 error when I try to
run my servlets (these worked with the earlier version).  
Here's Tomcat's response upon startup:
 
2000-08-06 09:58:21 - ContextManager: Adding context Ctx( /papernet )
Starting tomcat. Check logs/tomcat.log for error messages
2000-08-06 09:58:21 - ContextManager: Adding context Ctx(  )
2000-08-06 09:58:21 - ContextManager: Adding context Ctx( /test )
2000-08-06 09:58:21 - ContextManager: Adding context Ctx( /examples )
2000-08-06 09:58:21 - ContextManager: Adding context Ctx( /admin )
cannot load servlet name: default
2000-08-06 09:58:23 - PoolTcpConnector: Starting HttpConnectionHandler on
8080
2000-08-06 09:58:23 - PoolTcpConnector: Starting Ajp12ConnectionHandler on
8007
 
Could anyone suggest to me what the "failure to load default servlet" error
message means, and if this might be the root of my trouble?  
In moving to 3.2b I only configured tomcat.conf, tomcat-apache.conf, and
server.xml. 
 
Thanks in advance for any insight you might have.
