System and method for connecting wireless applications to heterogeneous backend servers via a gateway server
A connector facilitates delivery of a message received from an application to one of a plurality of heterogeneous backend servers via a gateway server. The message is defined in a schema-based description document in accordance with a set of predefined criteria specific to the connector. The connector comprises a processor for encapsulating the message in accordance with a binding protocol defined by the schema-based description document a transceiver for transmitting the message in accordance a connection protocol defined by with the schema-based description document.
1 . A connector for facilitating delivery of a message received from an application to one of a plurality of heterogeneous backend servers via a gateway server, the message being defined in a schema-based description document in accordance with a set of predefined criteria specific to the connector, the connector comprising:
(a) a processor for encapsulating the message in accordance with a binding protocol defined by the schema-based description document; and
(b) a transceiver for transmitting the message in accordance a connection protocol defined by with the schema-based description document.
2 . The connector of claim 1 , wherein the schema-based description document is defined in accordance with the Web Services Definition Language (WSDL).
3 . The connector of claim 2 , wherein the binding protocol is defined using extensibility of the WSDL binding element.
4 . The connector of claim 2 , wherein the connection protocol is defined using extensibility of the WSDL service element.
5 . A gateway server for facilitating delivery of a message received from an application to one of a plurality of heterogeneous backend servers, the message being defined in a schema-based description document in accordance with a set of predefined criteria, the gateway server comprising:
(a) a message interface and receiving messages from and transmitting messages to the application; and
(b) a connector for communicating with the backend server, the connector comprising:
a processor for encapsulating the message in accordance with a binding protocol defined by the schema-based description document, wherein the predefined criteria are specific to the connector; and
a transceiver for transmitting the message to the backend server in accordance a connection protocol defined by with the schema-based description document.
6 . The gateway server of claim 5 , wherein the schema-based description document is defined in accordance with the Web Services Definition Language (WSDL).
7 . The gateway server of claim 6 , wherein the binding protocol is defined using extensibility of the WSDL binding element.
8 . The gateway server of claim 6 , wherein the connection protocol is defined using extensibility of the WSDL service element.
9 . The gateway server of claim 5 , wherein the schema-based description document is publicly available before implementation on the gateway server and potentially sensitive data is separate from the schema-based description document and maintained as private.
10 . The gateway server of claim 9 , further including a merge processor for merging the potentially sensitive data with the publicly available schema-based description document for execution on the gateway server.
