HTTP 503 error for all servlets

[Todd Young <ty...@yahoo.com>]

I'm trying to run Tomcat 4.0.4 and get HTTP 503 errors
for all servlets including the examples. I only have
one instance of the servlet.jar file in my classpath,
and it's the one that came with the 4.0.4
distribution. I get the following exception --
