Gears security considerations
The BlackBerry® Browser is designed to prevent the databases of one Gears™ application from accessing the databases of another application. Gears applications on the BlackBerry Browser can access only those resources with the same scheme, domain, and port number, as the application.
The BlackBerry Browser creates a database for an application in a domain-specific subfolder within a Gears-specific folder. For example, for a Gears application located at www.mycompany.com/gearsapp, the browser creates a database in the following location on a media card:
An application can access a database only by using path names that are relative to the origin domain. Applications cannot access databases using absolute path names.
