The Fedora 8 implementation of tomcat5 and jetty has a major bug: both tomcat5 and jetty, as packaged by the providers, use the same port by default. Usually jetty is started up before tomcat5, and this guarantees that tomcat5, by default, will break because jetty is listening on that same port. To fix the problem, you need to edit /etc/tomcat5/server.xml and change the default connector port number. Why does Fedora 8 include jetty? Because Fedora Eclipse needs it. The default implementations of tomcat5 and jetty need to change to so that they use different port numbers of both these packages are being installed. I don't know if this has any bearing on your problem -- on the surface of it, doesn't seem so -- but I wanted to mention this.
