Error Log view which will show you a stack trace...

See if this item[1] in the Tomcat FAQ helps. If not, a full stack trace
and more info about your OS and version of Eclipse and WTP would help.
Cheers,

I'm running Windows XP, service pack 2. Eclipse info is
Version: 3.3.1.1
Build id: M20071023-1652
The WTP version appears to be 1.1.X. I seem to have 6 WTP plugins, with
final version numbers ranging from 100 to 102.
Thanks,
Rich

These exceptions suggest that the Tomcat plug-in is having trouble
understanding customizations that may have been made to the server.xml
in your installation. This file is imported from your Tomcat
installation into a sub folder of the Servers folder in your workspace.
It appears that there is a problem identifying the <Service>,
<Engine>, or <Host> that should be used. If you can attach a copy of
the server.xml from the Servers project in your workspace, I'll take a
look and see if I can spot anything.
Cheers,
Larry

That got it! The defaultHost field of the Engine tag was set to a
non-existent host. We've been using IntelliJ and apparently it ignores
that field. I changed it to "localhost" (which is correct b/c I'm only
using it for testing) and it started up.
Thanks,
Rich
