Abstract

A method for remotely using a data-processing object accessible via a server station connected to a communications network, from a client station connected to the network, comprises the steps of: sending an object request to the server station, the object request including information for identifying an object accessible via the server station; reception of an object response sent by the server station, the object response including information for describing a user interface, the information being associated with programmed functions, the interface allowing a user to use the object; starting up the user interface on the client station; execution of at least one function associated with one element of the user interface, in response to the activation of this element by a user; sending a method-execution request to the server station, in response to the execution of at least one programmed function associated with the element activated, the method-execution request including the information for identifying the object and at least one command which can be understood by the object.

7. A method according to claim 1, wherein the programmed functions associated with the information for describing a user interface are implemented in the Javascript programming language.

8. A method according to claim 1, wherein the at least one command consists in the designation of a function of the object, and in the passing of values given to parameters associated with the designated function.

9. A method according to claim 1, wherein the communications network is a network of the Internet type.

10. A method according to claim 1, wherein the client station and the server station communicate by using a communications protocol of the “

hypertext transfer protocol”

(HTTP) type, and in that the messages exchanged between the client station and the server station are HTTP messages.

26. A device according to claim 24, including means suitable for implementing a method for remotely using a data-processing object according to any one of claims 3 to 10.

11. A method for executing a function on a data-processing object which can be used, via a server station connected to a communications network, by at least one client station connected to the network, comprising the following steps, implemented in the server station:

receiving an object request originating from a client station, the object request including information for identifying a data-processing object accessible via the server station;

sending an object response to the client station, the object response including information for describing a user interface, the information being associated with programmed functions, the interface allowing a user to use the object;

receiving a method-execution request originating from the client station, the method-execution request including the information for identifying the object and at least one command which can be understood by the object.

12. A method according to claim 11, further comprising the following steps:

executing the at least one command received from the client station, on a data-processing object;

sending a method-execution response to the client station, the method-execution response containing data indicative of the result of the execution of the at least one command on the object.

13. A method according to claim 11, wherein the at least one command, which can be understood by the object and which is contained in the method-execution request, consists in the designation of a function of the data-processing object in question, and in the passing of values given to parameters associated with the designated function.

14. A method according to claim 11, wherein the information for identifying an object comprises an electronic address indicative of the storage location of the object.

15. A method according to claim 14, wherein the electronic address indicative of the storage location of the object is a URL-type address.

16. A method according to claim 11, wherein the information for describing a user interface is data expressed in a data-processing communications language of the “

markup language”

type.

17. A method according to claim 16, wherein the communications language is based on the XML language.

18. A method according to claim 11, wherein, in order to be accessible on the network, the data-processing object is associated in the server station with an electronic document containing the information for describing at least one user interface and the associated programmed functions.

19. A method according to claim 18, wherein the electronic document is a document of the “
