Abstract

A system for generating an interface for a software application in a client-server environment. A projector runs on a server computer and processes a software application having an interface component and a code component. A thin client program called a viewer runs on a client computer that remotely accesses the software application on the projector. The projector transmits to the viewer only the interface component of the software application. The interface component includes information about all the widgets needed to execute the application, such as their placement, size, and captions. The viewer renders the graphical user interface with the native widget set of the client computer'"'"'s operating system, based on the widget information from the projector. Therefore, the native widget set dictates the appearance of the widgets, such as their style and shape, and the interface for the application looks and feels like a native desktop application.

12. The system of claim 1 wherein the at least one software application is published on said projector when the interface component and the code component of the at least one software application are stored in the server computer.

13. The system of claim 12 wherein the interface component includes handler code that is translated to byte code when the at least one software application is published on said projector.

14. The system of claim 12 wherein the at least one software application is accessible to the at least one client computer once the at least one software application is published on said projector.

15. The system of claim 1 wherein said at least one viewer is a thin client program.

16. The system of claim 1 wherein said at least one viewer is portable across a plurality of operating systems, including operating systems selected from the group consisting of Microsoft'"'"'s Windows and Linux.

17. The system of claim 1 wherein said projector provides said at least one viewer with the interface component of the at least one software application in a descriptive language.

18. The system of claim 17 wherein the descriptive language is Extensible Markup Language.

19. The system of claim 1 wherein the information about the at least one widget is stored in a local repository on the at least one client computer.

20. The system of claim 1 wherein the information about the at least one widget includes information selected from the group consisting of placement of the widget, size of the widget, and caption for the widget.

21. The system of claim 1 wherein the information about the at least one widget does not include information selected from the group consisting of shape of the widget, style of the widget, and color of the widget.

22. The system of claim 1 wherein said at least one viewer transmits all user interaction with the graphical user interface to said projector.

23. The system of claim 1 wherein the at least one client computer connects to server computer via the Internet or an intranet.

24. The system of claim 1 wherein the graphical user interface for the at least one software application appears like a native software application on the at least one client computer.

25. The system of claim 1 wherein said at least one viewer maintains state with the said projector while the at least one software application is executed by the at least one client computer.

26. The system of claim 1 wherein said projector is configured to define user access to the at least one software application.

27. The system of claim 26 wherein said projector is configured to track usage of the at least one software application by each user.

28. The system of claim 27 wherein said projector is configured to generate bills for usage of the at least one software application in predetermined increments.

30. The method of claim 29 further comprising the step of updating the graphical user interface on the client computer during execution of the software application by the client computer with the native widget set of the client computer based on the information about the at least one widget stored on the client computer.

31. The method of claim 29 further comprising the step of processing the code component of the software application in the server during execution of the software application by the client computer.

32. The method of claim 29 further comprising the step of maintaining state between the client computer and the server computer during execution of the software application by the client computer.
