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.
