By the way, when using Eclipse it is not port 8080 that is important at startup, but rather port 1099 - the JNDI port. Eclipse makes a JNDI call to port 1099 asking for the JMX server and then asks the JMX server for the Server MBean which it then queries to see if the server got started. If anything fails along the way, Eclipse reports that the app server did not start in time.

There are a multitude of things that can go wrong with this (the forum is full of posts where this has happened). Typical problems are:

* The user changed the ports
* The /etc/hosts file has invalid inforation in it
* The user bound the app server to a host other than localhost or 0.0.0.0
* The system is configured without the loopback adaptor (this was a new one, at least to me, that just came up a few days ago)
* Just plain general wierdness in Eclipse or the JDK (installing a new Eclispe or JDK magically solved the issue)

Sometimes if you go into the Eclipse log file (workspace/.metadata/.log) you can figure out where things went wrong and correct them. But only sometimes.
