Abstract

Systems and techniques for operating a Web browser as if the Web browser were a Web service server with and without a business process engine. Data fields in a HTML Web page under naming conventions are mapped into tree-structured data fields of a XML document so that a response from the Web browser can be represented as an output of a Web Service server.

Claims

1. A Web Service interface module for presenting a Web browser as a Web Service server, comprising:

a hypertext transfer protocol (HTTP) server to send Web pages to and to receive Web pages from a Web browser in the Hypertext Markup Language (HTML); and

a servlet operable to decode data that is from a Web page in HTML and received by the HTTP server, according to a naming convention used in the Web page in HTML, into an Extensible Markup Language (XML) document holding information in the data in a tree-structure.

2. A module as in claim 1, further comprising a plurality of JavaServer pages connected to receive an XML document from the servlet and operable to convert the XML document into a HTML Web page, wherein the JavaServer pages are operable to direct each HTML Web page to the HTTP server.

3. A module as in claim 2, further comprising a business processing engine in communication with the servlet to control a sequence of the JavaServer pages.

4. A module as in claim 1, wherein the servlet is operable to communicate a decoded XML document to the HTTP server which outputs the decoded XML document to a Web Service client.

5. A method, comprising:

sending Web pages in a Hypertext Markup Language (HTML) to a Web browser to obtain information from a user of the Web browser;

receiving user data entered into the Web pages in HTML from the Web browser;

using a naming convention in the received user data to decode the received user data into an Extensible Markup Language (XML) document having a tree-structure that holds the information in the received user data; and

delivering the XML document to a Web Service client which requests for the information in the XML document.

6. A method as in claim 5, wherein a hypertext transfer protocol (HTTP) server is used for sending and receiving the Web pages.

7. A method as in claim 5, further comprising using logic in a business process engine to control a page flow of the Web pages sent to the Web browser.

8. A method as in claim 5, further comprising using a Java servlet and predefined JavaServe pages to control a page flow of the Web pages sent to the Web browser without a business process engine.

9. An article comprising one or more machine-readable storage media that store machine-executable instructions operable to cause a machine to

dispatch pre-defined Web pages in a Hypertext Markup Language (HTML) to a Web browser used by a user for obtaining information from the user to respond to a Web Service request;

and

apply HTML naming conventions to process returned Web pages from the Web browser and to convert a response by the user in HTML into an Extensible Markup Language (XML) document having a tree-structure.

10. An article as in claim 9, wherein the instructions further include a set of instructions to cause the machine to deliver the XML document to reply to the Web Service request.

11. An article as in claim 9, wherein the instructions further include a set of instructions to cause the machine to use the hypertext transfer protocol (HTTP) to dispatch the pre-defined Web pages.

12. An article as in claim 9, wherein the instructions further include a set of instructions to cause the machine to generate a graphic user interface to graphically represent a mapping relationship between information in a HTML document and information in a tree-structured XML document.

13. An article as in claim 12, wherein the instructions further include a set of instructions to cause the machine to

create two separate graphic panes in the graphic user interface to represent fields of the HTML document and fields of the XML document, respectively, and

provide graphic icons for linking the two separate graphic panes.

14. A method, comprising:

applying HTML naming conventions to map data in a HTML Web page from a Web browser into tree-structured data fields of a XML document for a Web Service; and

using the XML document to reply to a Web Service request which initiates the HTML Web page from the Web browser to represent the Web browser as a Web service server.

15. A method as in claim 14, further comprising using a hypertext transfer protocol (HTTP) server to send Web pages to and receive Web pages from the Web browser.

16. A method as in claim 15, wherein a Java servlet is used for mapping the data.

17. A method as in claim 14, further comprising using a graphic user interface to graphically represent the mapping between data fields in the HTML Web page and data fields in the tree-structured data fields of the XML document.

18. A method as in claim 17, further comprising:

providing two separate graphic panes in the graphic user interface to represent data fields of the HTML Web page and the tree-structured data fields of the XML document, respectively, and providing graphic icons for linking the two separate graphic panes.
