Reloading an application simply restarts the application without redeploying it, preserving the settings and other options with which the application was deployed.
The Applications page opens.
The application name can include an optional version identifier, which follows the name and is separated from the name by a colon (:). For more information about module and application versions, see the Module and Application Versions in Oracle GlassFish Server 3.1 Application Deployment Guide.
The Applications page appears again, with a message stating whether the reload succeeded.
