Abstract

A method for creating a web service to programmatically access a network addressable location via an intermediate gateway includes analyzing a network at the location; generating, at the gateway, a service description file and an executable code for the network page; translating the service description file into a standard Web service format; deploying the service to the gateway, making the service available to a client application; providing a runtime process to enable the client application to automatically make a programmatic request of the location; translating the structure of the request to a syntax of location using SOAP; submitting the request to the location which executes the submitted request to obtain a response; translating the response to extract data satisfying the request; wrapping the extracted data in a SOAP envelope; translating the wrapped response to a host data structure of the client application; and compiling the executable code.

Claims

1. A processor-implemented method for creating a web service to programmatically access a network addressable location via an intermediate gateway, comprising:

analyzing a network page at the network addressable location;

generating, at the intermediate gateway, a service description file for the network page;

translating the service description file into an executable code;

translating the service description file into a standard Web service format including at least one of web service description language (WSDL), well-defined service (WDS), or interface service deployment (ISD);

compiling the executable code;

deploying the web service to the intermediate gateway, wherein the web service includes the compiled executable code and the translated service description file, making the web service available to a client application;

providing a runtime process to enable the client application to automatically make a programmatic request of the network addressable location;

wherein the programmatic request includes a host language having a structure;

translating the structure of the programmatic request to a syntax of the network addressable location using a simple object access protocol (SOAP);

submitting the programmatic request that uses the translated structure to the network addressable location using SOAP;

the network addressable location executing the submitted programmatic request to obtain a response;

translating the response to extract data satisfying the programmatic request;

wrapping the extracted data in a SOAP envelope; and

translating the wrapped response to a host data structure of the client application.

2. The method of claim 1, further comprising registering the web service in a universal description, discovery, and integration (UDDI) registry.

3. The method of claim 1, further comprising returning the translated, retrieved network page in a predetermined syntax to the client application.

4. The method of claim 3, wherein the predetermined syntax includes XHTML.

5. The method of claim 1, wherein the service description of the network page contains the following information:

an application programming interface description in the form of a web services description language file;

a well-defined service file, and an interface service deployment file.

6. The method of claim 1, further comprising deploying the executable code in the simple object access protocol (SOAP) service manager using the interface service deployment file.

7. The method of claim 6, further comprising publishing the executable code that has been deployed in the simple object access protocol service manager in a registry using the web services description language file and the well-defined service file.

8. The method of claim 6, wherein the simple object access protocol request includes the simple object access protocol request that is based on XML syntax.

9. A computer program product having executable instruction codes that are stored on a computer usable medium, for creating a web service to programmatically access a network addressable location via an intermediate gateway, comprising:

a set of instruction codes for analyzing a network page at the network addressable location;

a set of instruction codes for generating, at the intermediate gateway, a service description file for the network page;

a set of instruction codes for translating the service description file into an executable code;

a set of instruction codes for translating the service description file into a standard Web service format including at least one of web service description language (WSDL), well-defined service (WDS), or interface service deployment (ISD);

a set of instruction codes for compiling the executable code;

a set of instruction codes for deploying the web service to the intermediate gateway, wherein the web service includes the compiled executable code and the translated service description file, making the web service available to a client application;

a set of instruction codes for providing a runtime process to enable the client application to automatically make a programmatic request of the network addressable location;

wherein the programmatic request includes a host language having a structure;

a set of instruction codes for translating the structure of the programmatic request to a syntax of the network addressable location using a simple object access protocol (SOAP);

a set of instruction codes for submitting the programmatic request that uses the translated structure to the network addressable location using SOAP;

the network addressable location executing the submitted programmatic request to obtain a response;

a set of instruction codes for translating the response to extract data satisfying the programmatic request;

a set of instruction codes for wrapping the extracted data in a SOAP envelope; and

a set of instruction codes for translating the wrapped response to a host data structure of the client application.

10. The computer program product of claim 9, wherein the service description of the network page contains the following information:

an application programming interface description in the form of a web services description language file;

a well-defined service file, and an interface service deployment file.

11. The computer program product of claim 10, further comprising a set of instruction codes for using the service description to generate and for compiling an executable program code.

12. The computer program product of claim 11, further comprising a set of instruction codes for deploying the executable program code in the simple object access protocol (SOAP) service manager using the interface service deployment file.

13. The computer program product of claim 12, wherein the simple object access protocol request includes the simple object access protocol request that is based on XML syntax.

14. A processor-implemented system for creating a service interface to programmatically access a network addressable location via an intermediate gateway, comprising:
