Yes, that helps considerably.

Great.  Not the most up-to-date, but at least 5.5.23 isn't *too* ancient :-).

Not a problem, Tomcat will run fine without it.

That's some very poor configuration somewhere in your conf/server.xml
- if that's the CentOS default, then some packager needs their wrists
slapping.  Hard.

Same again - if rhn is a RedHat-supplied app, including the API jars
is Very Poor Practise.  Tomcat's smart enough to ignore them, but it's
a good indication that whoever wrote this didn't know what they were

Looks like the app's using c3p0 connection pooling.  I think that's a
consequence of...

That's the rhn app being unable to get hold of a database connection,
probably because you haven't configured one.  Do you need this app or
can you bin it?

Then I'm very worried, as you should at least have a shutdown port
(usually 8005).

Could you post your conf/server.xml here, preferably with comments
stripped and any sensitive hostnames, usernames and passwords blanked?
 That would tell us a lot more.  You might have to hunt for it, but it
should be a file called server.xml *somewhere* on your system!

It looks like Spacewalk is trying to talk from Apache httpd to Tomcat
via AJP (which uses port 8009), but Tomcat's not configured with an
AJP connector to listen on 8009.  That would certainly give the
symptoms you're observing.
