The inclusion of metadata within an application description file allows a virtual machine to create an application descriptor file that may be registered with the mobile device operating system so that an icon associated with the application description file may be displayed in the main ribbon. Execution of an application defined by the application definition file may then be initiated by the selection, by the user, of the icon that is associated with the application definition file. This improves over the situation wherein execution of the application defined by the application definition file would require a selection of the runtime environment for the application and then the selection of the application.
