Initialization of Dispatcher Failed

[Tancreto, John]

When starting up The Tomcat 3.3.1a (startup.bat on Win2000), I get the
following error message in the prompt window:

WARNING: Dispatcher could not be set up:

javax.servlet.UnavailableException: Initialization of Dispatcher failed

cher.java:153)
        at java.lang.Thread.run(Thread.java:479)

Do you know what may be causing this issue?

Thanks,

John
