Abstract

The invention provides a method and apparatus for a web-related state machine. In one embodiment, the method may include coordination of action states and display states through use of a state machine servlet. The method may further include maintenance of an environment for the action states and display states through use of the state machine servlet.

Claims

1. A method of operating a web site, comprising:

coordinating states of a web site, the states including code which effects the display and actions of the web site and at least one wizard operable to receive orders and to generate orders, wherein the display includes a user login screen;

receiving a user ID and a password from a user;

passing execution to an action state after receiving the user ID and the password;

maintaining a history of user interaction with the web site; and

maintaining an environment of the web site, the code of the states having access to the environment, wherein maintaining the environment includes maintaining the user ID and the password in the environment.

2. The method of claim 1, wherein:

the coordinating and maintaining are performed by a state machine; and

the state machine interacting with the states.

3. The method of claim 2, wherein:

maintaining the environment includes creating and managing environment data.

4. The method of claim 2, wherein:

interacting with the states includes receiving indications of success or failure from the states, supplying environment data to the states and receiving changes to environment data from the states.

5. A system for operating a web site with a state machine, comprising:

means for coordinating states of a web site, the states including code which effects the display and actions of the web site and at least one wizard operable to receive orders and to generate orders, wherein the display includes a user login screen;

means for receiving a user ID and a password from a user;

means for passing execution to an action state after receiving the user ID and the password;

means for maintaining a history of user interaction with the web site; and

means for maintaining an environment of the web site, the code of the states having access to the environment, wherein the means for maintaining the environment includes means for maintaining the user ID and the password in the environment.

6. The system of claim 5, further comprising:

means for interacting with the states.

7. A machine-readable medium embodying a plurality of instructions, the plurality of instructions when executed by a processor, causing the processor to perform the method comprising:

coordinating states of a web site, the states including code which effects the display and actions of the web site and at least one wizard operable to receive orders and to generate orders, wherein the display includes a user login screen;

receiving a user ID and a password from a user;

passing execution to an action state after receiving the user ID and the password;

maintaining a history of user interaction with the web site; and

maintaining an environment of the web site, the code of the states having access to the environment, wherein maintaining the environment includes maintaining the user ID and the password in the environment.

8. The machine-readable medium of claim 7 embodying additional instructions, the additional instructions when executed by a processor, causing the processor to perform the method wherein:

the coordinating and maintaining are performed by a state machine; and

the state machine interacting with the states.

9. The machine-readable medium of claim 8 embodying additional instructions, the additional instructions when executed by a processor, causing the processor to perform the method wherein:

maintaining the environment includes creating and managing environment data.

10. The machine-readable medium of claim 8 embodying additional instructions, the additional instructions when executed by a processor, causing the processor to perform the method wherein:

interacting with the states includes receiving indications of success or failure from the states, supplying environment data to the states and receiving changes to environment data from the states.
