Abstract

A system for providing web services to a client over a network includes an interface module in communication with the network, an implementation module in communication with the interface module, and a fulfillment module in communication with the implementation module and at least one database. The interface module receives the web service request from the client, passes the request to at least one other component of the system, and passes assimilated data to the client in response to the web service request. The implementation module assimilates data provided by at least one other component of the system in response to the service request. The fulfillment module extracts data from at least one database in response to the service request and provides the extracted data to the implementation module.

Claims

1. A system for providing web services comprising:

at least one server computer having an interface for communicating over a network;

an interface module in communication with the server computer, the interface module comprising software for receiving a service request from a client, passing the request to at least one other component of the system, and passing assimilated data to the client in response to the service request;

an implementation module in communication with the interface module, the implementation module comprising software for assimilating data provided by at least one other component of the system in response to the service request; and

a fulfillment module in communication with the implementation module, the fulfillment module comprising software for extracting data from at least one database in response to the service request and providing the extracted data to the implementation module.

2. The system of claim 1, wherein the interface module, implementation module and fulfillment module are hosted on the server computer.

3. The system of claim 1, where the at least one database includes a product catalog database.

4. The system of claim 1, where the at least one database includes a product configurator database.

5. The system of claim 1, where the at least one database includes a product order database.

6. The system of claim 1, where the at least one database includes an enterprise resource planning database.

7. The system of claim 1, wherein the interface module comprises a SOAP engine.

8. The system of claim 7, wherein the SOAP engine is HP-SOAP.

9. The system of claim 7, wherein the SOAP engine is Apache SOAP.

10. The system of claim 7, wherein the SOAP engine is Apache Axis.

11. The system of claim 1, wherein the implementation and fulfillment module software comprises object oriented programming.

12. The system of claim 11, wherein the implementation and fulfillment modules software comprise Enterprise Java Beans.

13. The system of claim 12, wherein the implementation module software comprise Java Session Beans.

14. The system of claim 12, wherein the fulfillment module software comprise Java Entity Beans.

15. The system of claim 11, wherein the object oriented programming is Java.

16. The system of claim 1, wherein the interface module communicates with the implementation module using SOAP.

17. The system of claim 1, wherein the implementation module communicates with the fulfillment module using RMI.

18. The system of claim 1, wherein the fulfillment module communicates with the database using JDBC.

19. An apparatus for providing a web service comprising:

a foundation layer containing data required to provide a web service;

a toolkit layer containing software tools to provide the web service using data from the foundation layer;

an application server layer containing software modules for receiving the a web service request from a client and invoking software tools in the toolkit layer to provide the web service; and

at least one server computer in communication the application server layer and a computer network.

20. The apparatus of claim 19, wherein the software modules of the application server layer comprise:

an interface module in communication with the computer network, the interface module comprising software for receiving a web service request, passing the request to at least one other component of the framework, and passing assimilated data to the client in response to the web service request;

an implementation module in communication with the interface module, the implementation module comprising software for assimilating data provided by at least one other component of the framework in response to the service request; and

a fulfillment module in communication with the implementation module, the fulfillment module comprising software for interacting with tools in the toolkit layer in response to the web service request.

21. The apparatus of claim 20, wherein the fulfillment module further comprises software for interacting with data in the foundation layer in response to the web service request.

22. The apparatus of claim 19, wherein the computer network is the internet.

23. The apparatus of claim 19, wherein the foundation layer includes an enterprise resource planning database.

24. The apparatus of claim 19, wherein the toolkit layer includes a product catalog database.

25. The apparatus of claim 19, wherein the toolkit layer includes a configurator database.

26. The apparatus of claim 19, wherein the toolkit layer includes a product order database.

27. The apparatus of claim 19, wherein the software modules of the application server layer use object oriented programming.
