Abstract: Embodiments of the present invention are directed to a method and system for device specific optimization of applications via a portal server. In one embodiment, a plurality of applications are resident upon a portal server. A plurality of application helper modules are respectively associated with each of the plurality of applications. Based upon the device type of a device requesting access to the portal server, an appropriate application helper is selected. When portal server requests a function to performed by the appropriate application helper module, the application helper module provides a link to the particular application. The portal server then displays the link to the particular application within a user-customizable display. The function requested can be to launch the application, or to perform some sub-process of the application.

Abstract: A single-sign-on adapter (SSO Adapter) implementing one or more authentication mechanisms that may be used by Portal middleware on behalf of a portal user. A user seeking access to a resource server through a portal server performs a single sign-on with the portal server at the beginning of a session. When requests a resource from resource server that requires authentication, the authentication is handled by the portal server without requiring an authentication response from the user. The portal server may use stored user credentials, a token-based shared authentication service, or proxy authentication in order to gain access to the resource server on behalf of the portal user.

Abstract: A method for providing extensible client mail functions to a plurality of clients via the Internet. The method includes a portal server receiving a request for mail functions from a client. In response to the request, a Java server page corresponding to the request is accessed. A plurality of tags contained within the Java server page are then accessed. The Java server page is subsequently processed using the tags, wherein the tags provide access to a mail server configured for providing the mail functions. The resulting processed Java server page is then transmitted back to the client. When requests from the client received, the Java server page corresponding to the request can be retrieved from a set of compiled Java server page classes. Extended mail functions can be provided by accessing a plurality of extended tags contained within the Java server page, wherein the mail functions are extended by adding the extended tags corresponding to new mail functionality of the mail server.

Abstract: A method for providing extensible client address book functions to a plurality of clients via the Internet. The method includes a portal server receiving a request for address book functions from a client. In response to the request, a Java server page corresponding to the request is accessed. A plurality of tags contained within the Java server page are then accessed. The Java server page is subsequently processed using the tags, wherein the tags provide access to an address book server configured for providing the address book functions. The address book functions include contact information, phone number information, mailing information, and the like. The resulting processed Java server page is then transmitted back to the client. When requests from the client received, the Java server page corresponding to the request can be retrieved from a set of compiled Java server page classes.

Abstract: A method for providing extensible client calendar functions to a plurality of clients via the Internet. The method includes a portal server receiving a request for calendar functions from a client. In response to the request, a Java server page corresponding to the request is accessed. A plurality of tags contained within the Java server page are then accessed. The Java server page is subsequently processed using the tags, wherein the tags provide access to a calendar server configured for providing the calendar functions. Calendar functions include, for example, appointments, work scheduling, reminders, and the like. The resulting processed Java server page is then transmitted back to the client. When requests from the client received, the Java server page corresponding to the request can be retrieved from a set of compiled Java server page classes.
