If the startup command starts the Apache Geronimo server, shutdown will definitively stop it. This command has the following syntax:

<geronimo_home>/bin/shutdown [options]

The available options are:

--user [user_name]
Specifies the user name with the authority to stop the server. By default you would normally use system as the user name.

--password [password]
Specifies the password for the user name you just entered. By default you would normally use manager as the password.

--port [port_number]
Specifies the RMI naming port to connect to the server (for example JMX connection port). By default you would normally use port 1099.

If you do not specify any parameters, this command will prompt you for a user name and password and will assume port 1099 by default and will not prompt for any port.
