Abstract

A computer implemented method includes receiving a request that includes an action parameter and identifying a procedure that is associated with the value of the action parameter. If a procedure is identified, the identified procedure is executed. If a procedure is not identified, a script associated with the value of the action parameter is dispatched.

Claims

1. A computer implemented method comprising:

receiving a request that includes an action parameter;

identifying a procedure that is associated with the value of the action parameter;

if a procedure is identified, executing the identified procedure; and

if a procedure is not identified, dispatching to a script associated with the value of the action parameter.

2. The method of claim 1, wherein the request is a hypertext transfer protocol request.

3. The method of claim 1, wherein the procedure is a method used in an object oriented programming language.

4. The method of claim 1, wherein the procedure is a function used in a procedural programming language.

5. The method of claim 1, wherein identifying a procedure that is associated with the value of the action parameter comprises searching a group of procedures in a program for a procedure that is associated with the value of the action parameter.

6. The method of claim 5, wherein searching a group of procedures in a program comprises searching a group of procedures in a program for a procedure that has a name equal to the value of the action parameter.

7. The method of claim 5, wherein searching a group of procedures comprises searching a group of methods in a class for a method that is associated with the value of the action parameter.

8. The method of claim 7, wherein searching a group of procedures comprises searching a group of methods in a class for a method that is associated with the value of the action parameter and that is programmed in Java™

.

9. The method of claim 5, wherein searching a group of procedures comprises searching a group of functions in a program for a function that is associated with the value of the action parameter.

10. The method of claim 9, wherein searching a group of procedures comprises searching a group of functions in a program for a function that is associated with the value of the action parameter and that is programmed in Perl.

11. The method of claim 1, wherein dispatching to a script associated with the value of the action parameter comprises dispatching to a script saved under a file name corresponding to the value of the action parameter.

12. The method of claim 1, wherein identifying a procedure comprises searching a group of procedures in a program for a procedure that is associated with the value of the action parameter and that includes code that implements application control logic.

13. The method of claim 1, wherein identifying a procedure comprises searching a group of procedures in a program for a procedure that is associated with the value of the action parameter and that includes code that enables communications with backend systems.

14. The method of claim 1, wherein dispatching to a script comprises dispatching to a script that is associated with the value of the action parameter and that includes code that implements presentation logic.

15. The method of claim 14, wherein the presentation logic implements a user interface.

16. The method of claim 15, wherein the user interface is a voice user interface operable to communicate with a user of a voice communication device.

17. The method of claim 16, wherein the voice communication device comprises a landline phone, a wireless phone, a voice-enabled personal digital assistant, or a voice-enabled computer.

18. The method of claim 1, wherein the script that is associated with the value of the action parameter includes markup language code.

19. The method of claim 18, wherein the markup language code comprises hypertext markup language.

20. The method of claim 18, wherein the markup language code comprises VoiceXML or SALT.

21. The method of claim 18, wherein the markup language code comprises markup language used to communicate with wireless communication devices.

22. The method of claim 21, wherein the markup language used to communicate with wireless communication devices includes wireless markup language.

23. The method of claim 1, further comprising dispatching to the script after executing the procedure if executing the procedure does not result in a response being committed.

24. A computer system comprising:

a web application computer configured to;

receive a request that includes an action parameter;

identify a procedure that is associated with the value of the action parameter;

execute the procedure if a procedure is identified; and

dispatch to a script associated with the value of the action parameter if a procedure is not identified.

25. The computer system of claim 24, wherein the request is a hypertext transfer protocol request.

26. The computer system of claim 24, wherein the procedure is a method.

27. The computer system of claim 24, wherein the procedure is a function.

28. The computer system of claim 24, wherein the web application computer is further configured to send a response.

29. The computer system of claim 24, further comprising a gateway computer.

30. The computer system of claim 29, wherein the gateway computer is a gateway configured to communicate with a wireless communication device.

31. The computer system of claim 30, wherein the gateway computer is a wireless application protocol gateway.

32. The computer system of claim 29, wherein the gateway computer is a voice gateway configured to communicate with a voice communication device.

33. The computer system of claim 24, wherein the web application computer is configured to dispatch to a script including markup language used for communication with a wireless communication device.

34. The computer system of claim 33, wherein the markup language includes wireless markup language code.

35. The computer system of claim 24, wherein the web application computer is configured to dispatch to a script including VoiceXML or SALT code.

36. The computer system of claim 24, wherein the web application computer is further configured to dispatch to the script after execution of the procedure if execution of the procedure does not result in a response being committed.
