Abstract:
A method for dynamically converting data between a mobile station in a wireless communication network and a resource server in a wide area network (WAN), the method comprising in sequence the steps of:(a) sending from the mobile station to a gateway server in the wireless communication network a request for a resource located on the resource server; (b) identifying, by an administrative module in the ateway server, a request chain of Java servlets appropriate for processing the request based on parameters contained in the request; (c) selectively invoking, by the administrative module, the request Java servlet chain identified in step (b); (d) re-formatting, by at least one Java request conversion servlet in the request Java servlet chain, the request for transmission over the WAN to the resource server; (e) selectively invoking, by the at least one Java request conversion servlet, a next Java servlet in the request Java servlet chain; (f) sending, by at least one Java fetch servlet in the request Java servlet chain, the re-formatted request from the gateway server over the WAN to the resource server; (g) receiving, by the at least one Java fetch servlet, the requested resource from the resource server at the gateway server; (i) selectively invoking, by the at least one Java fetch servlet, at least one Java content-parsing servlet; (j) sending, by the at least one Java fetch servlet, the requested resource to the at least one Java content-parsing servlet; (k) generating, by the at least one Java content-parsing servlet, information indicating a content type of the received requested resource; (l) selectively invoking at least one Java content conversion servlet appropriate for the content type of the received resource; and (m) converting, by the at least one Java contend conversion, servlet, the content type of the received requested resource to a different content type.
