Method and apparatus for managing Internet transactions
The object-oriented approach used by the present invention provides the ability to develop and manage Internet transactions. Local applications can be accessed using any workstation connected to the Internet regardless of the workstation's configuration. Some or all of a Web page can be generated dynamically using input received in a returned page, generated at runtime, or retrieved from an external data source (e.g., database or electronic mail system). When the Web page definition is rendered, the information contained in template(s), declaration file(s), and object(s) are used to generate standard definitions. State information is maintained across transactions. Using state information, virtual applications, sessions, transactions, and pages can be implemented. Self-contained modules, or components, provide the ability to share implementations and create multi-content documents. Event objects can be used to assist in event handling management.
1. A method for dynamically generating a web page definition, comprising:
creating an initial set of one or more objects, the initial set of one or more objects comprising an at least initial definition of at least a portion of a web page;
making at runtime a modification to said set of one or more objects; and
generating said web page definition by a computer device using said modified set of one or more objects;
wherein generating at runtime said web page definition using said modified set of one or more objects comprises generating one or more statements in a web page definition language at least one of which reflects said modification and wherein said one or more statements are generated by said modified set of one or more objects.
2. A method as recited in claim 1 , wherein making a modification to said set of one or more objects at runtime comprises adding a new object to said set of one or more objects.
3. A method as recited in claim 1 , wherein making a modification to said set of one or more objects at runtime comprises modifying an object in said set of one or more objects.
4. A method as recited in claim 3 , wherein modifying an object in said set of one or more objects comprises:
retrieving data from an external data source; and
modifying one or more properties of said object using said data.
5. A method as recited in claim 1 , wherein making a modification to said set of one or more objects at runtime comprises receiving user input with respect to one or more objects in said set of one or more objects and making said modification based at least in part on said user input.
6. A method as recited in claim 1 , wherein creating a set of one or more objects comprises maintaining state information for at least one object in said set of one or more objects.
7. A method as recited in claim 6 , wherein maintaining state information for said at least one object in said set of one or more objects comprises:
defining one or more properties for said state information; and
retaining said state information based at least in part upon said one or more properties.
8. A method as recited in claim 7 , wherein said one or more properties include one or more of a duration of said state information, a scope of said state information, and a storage policy for said state information.
9. A method as recited in claim 1 , wherein said web page definition comprises one or more components and wherein each of said one or more components defines a portion of said web page definition.
10. A method as recited in claim 9 , wherein said one or more components include said set of one or more objects.
11. A method as recited in claim 9 , wherein said one or more components comprise one or more of HTML, PDF, and VRML components.
12. A method as recited in claim 9 , wherein said web page definition comprises a first web page definition and further comprising using one or more components included in said first web page definition in a second web page definition.
13. A method as recited in claim 1 , wherein said web page definition generates a multi-content web page by combining a plurality of components and wherein each of said plurality of components defines a portion of said web page.
14. A method as recited in claim 1 , wherein at least one object in said set of one or more objects is associated with an element definition of said web page definition.
15. A method as recited in claim 1 , wherein said set comprises two or more objects.
16. A system for dynamically generating a web page definition, comprising:
a processor configured to:
create an initial set of one or more objects, the initial set of one or more objects comprising an at least initial definition of at least a portion of a web page;
make at runtime a modification to said set of one or more objects; and
generate said web page definition using said modified set of one or more objects; and
a memory coupled to said processor and configured to provide instructions to said processor;
wherein generating at runtime said web page definition using said modified set of one or more objects comprises generating one or more statements in a web page definition language at least one of which reflects said modification and wherein said one or more statements are generated by said modified set of one or more objects.
17. A system as recited in claim 16 , wherein to make a modification to said set of one or more objects at runtime comprises adding a new object to said set of one or more objects.
18. A system as recited in claim 16 , wherein to make a modification to said set of one or more objects at runtime comprises modifying an object in said set of one or more objects.
19. A system as recited in claim 16 , wherein to make a modification to said set of one or more objects at runtime comprises receiving user input with respect to one or more objects in said set of one or more objects and making said modification based at least in part on said user input.
20. A system as recited in claim 16 , wherein at least one object in said set of one or more objects is associated with an element definition of said web page definition.
21. A computer readable storage medium for dynamically generating a web page definition and comprising computer instructions when executed by a computer device for performing the steps of:
creating an initial set of one or more objects, the initial set of one or more objects comprising an at least initial definition of at least a portion of a web page;
making at runtime a modification to said set of one or more objects; and
generating said web page definition using said modified set of one or more objects;
wherein generating at runtime said web page definition using said modified set of one or more objects comprises generating one or more statements in a web page definition language at least one of which reflects said modification and wherein said one or more statements are generated by said modified set of one or more objects.
