Method and system for providing a state model of an application program
First Claim
1. A server-based method for providing remote access to a legacy application program over a communication network, comprising:
- determining logical elements of the legacy application program in accordance with corresponding states of the legacy application program;
determining a state model in accordance with the logical elements of the legacy application program, the state model associating the logical elements of the legacy application program with the corresponding states of the legacy application program;
generating a remote access program in accordance with the state model, the remote access program executing on a server computing device;
updating the state model in accordance with data received from a user interface program executing on a client computer and in accordance with application data received from the legacy application program;
enabling communication between the legacy application program and the client computer; and
providing application representation data generated in accordance with the application data to the user interface program to the client computer, the application representation data enabling the client computer to display the legacy application program in accordance with information contained in the state model.

Abstract
Methods and apparatuses for enabling remote access to an application program via a computer network provided. Logical elements of the application program may be determined, from which a state model of the application program may be developed. A remote access program updates the state model in accordance with user input data received from a user interface program, generates control data in accordance with the updated state model and provides the same to the application program. The state model may be updated in accordance with application data received from the application program, application representation data in accordance with the updated state model are generated and provided to the user interface program for display at, e.g., a remote client computing device. The application program may be a legacy mainframe application to which remote access is provided without the need to modify the source code of the mainframe application.
