JBoss recipe of the day
If you try to start JBoss from Eclipse, by default Eclipse has a 50 second limit which is really too short, especially if you are starting JBoss 5.X releases.

To overcome this limit you have two options:
  • Double click on the server icon (In the Servers tab). In the next panel choose an appropriate timeout for your server.

  • Start JBoss AS from the JBoss AS Server View. In order to do so, you have to install JBoss tools on your Eclipse.
