This page lists the applications that have been installed in the server and whether they are running or stopped. There are four columns; two provide information and the other two allow user action. The first column indicates the state of the application, either "stopped" or "running." The fourth column shows the configID of the application. The two remaining columns are:

Stop/Start The stop/start toggle can be clicked to stop or start an application. If the toggle says "Stop" the application is running so clicking on the Stop toggle will stop the application and vice versa.
Uninstall The uninstall link will undeploy/remove the application from Geronimo.
