Abstract

A system for collaborating components or objects in a visual development environment is detailed. Collaboration is effected by augmenting eligible components or objects with appropriate collaboration code and registering such components or objects with a server application designated for that purpose which resides on the same HTTP server where the applet that spawned the components to be collaborated also resides. The server application first registers objects or components or portions thereof to be collaborated, builds a record of such links and thereafter interacts with the collaborated components or designated portions thereof to publish, unpublish or update those components and objects, or portions thereof, in accordance with the application server record.

Claims

1. A method of creating collaborative relationships between objects, components or assemblies thereof that are part of the applet, which is resident on a hardware based server, utilizing a collaborative application server that is also resident on the hardware based server, said method comprising the steps of:

registering each object, component or assembly for which collaboration is desired with the application server as a registered object, component or assembly;

building a record within the application server of each of the registered objects, components, assemblies that are to be collaboratively linked;

receiving information, from each registered object, component or assembly that has been changed, of a change and of changed information association with the change; and

notifying each registered object, component or assembly that another object, component or assembly which is collaboratively linked has been changed.

2. The method according to claim 1 which comprises the additional step of having the application server instantiate each registered object, component or assembly as derived from the applet and then link them in accordance with the specific collaboration desired so that a linked network of collaborated objects, components or assemblies can be maintained by the application server.

3. The method according to claim 2 which comprises the additional step of having the notified objects, components or assemblies respond to the application server to advise when they will be ready to receive all updated information.

4. The method according to claim 1 which comprises the additional step of having the notified objects, components or assemblies respond to the application server to advise when they will be ready to receive all updated information.

5. The method according to claim 1 wherein the applet, application server and code for the registering, record building and notification steps are all written in Java or a Java compatible programming language.

6. The method according to claim 1 in which the step of notifying each registered object, component or assembly that another object, component or assembly to which it is collaboratively linked has been changed also includes an automatic update of each linked, but not yet changed collaborated object, component or assembly.

7. The method according to claim 6 wherein the applet, application server and code for the registering, record building and notification steps are all written in Java or a Java compatible programming language.

8. A system for creating a collaborative relationship between objects, components or assemblies thereof that are part of an applet, which is resident on a hardware based server, utilizing a collaborative application server that is also resident on the hardware based server, said system comprising:

an application server which registers each object, component or assembly for which collaboration is desired as a registered object, component or assembly;

records which are dynamically created, updated and stored within the application server of all objects, components, assemblies that are to be collaborative; and

a message transmitter, associated with the application server, transmits messages to each registered object, component or assembly that another object, component or assembly has changed.

9. The system according to claim 8 which additionally comprises application server linkage logic which instantiates each registered object, component or assembly and links them in accordance with collaboration requests creating a linked network of collaborated objects, components or assemblies.

10. The system according to claim 9 which additionally comprises notified objects, components or assemblies which respond to requests from the application server to provide status information.

11. The system according to claim 10 which additionally comprises notified objects, components or assemblies which respond to requests from the application server to provide an indicia of ready to receive.

12. The system according to claim 11, wherein the application server automatically updates each linked, but not yet changed collaborated object, component or assembly.

13. The system according to claim 10, wherein the application server automatically updates each linked, but not yet changed collaborated object, component or assembly.

14. The system according to claim 8, wherein the application server automatically updates each linked, but not yet changed collaborated object, component or assembly.

15. A computer program embodied on a computer-readable medium for creating a collaborative relationship between objects, components or assemblies thereof that are part of an applet, which is resident on a hardware based server, utilizing a collaborative application server that is also resident on the hardware based server, said embodied program comprising:

first software that registers each object, component or assembly for which collaboration is desired with the application server as a registered object, component or assembly;

second software that builds a record within the application server of all objects, components, assemblies that are to be collaborative;

third software that receives information from each registered object, component or assembly that has been changed of the change and of the changed information; and

fourth software that notifies each registered object, component or assembly that another object, component or assembly to which it is collaboratively linked has been changed.

16. The computer program embodied on a computer-readable medium as recited in claim 15 which additionally comprises fifth software for having the application server instantiate each registered object, component or assembly as derived from the applet and then link them in accordance with the specific collaboration desired so that a linked network of collaborated objects, components or assemblies can be maintained by the application server.

17. The computer program embodied on a computer-readable medium as recited in claim 16 which additionally comprises sixth software for having the notified objects, components or assemblies respond to the application server to advise when they will be ready to receive all updated information.

18. The computer program embodied on a computer-readable medium as recited in claim 15 which additionally comprises sixth software for having the notified objects, components or assemblies respond to the application server to advise when they will be ready to receive all updated information.

19. The computer program embodied on a computer-readable medium as recited in claim 15 which additionally comprises sixth software for notifying each registered object, component or assembly that another object, component or assembly to which it is collaboratively linked has been changed and for automatically updating each linked, but not yet changed collaborated object, component or assembly.

20. The computer program embodied on a computer-readable medium as recited in claim 17 which additionally comprises seventh software for notifying each registered object, component or assembly that another object, component or assembly to which it is collaboratively linked has been changed and for automatically updating each linked, but not yet changed collaborated object, component or assembly.

21. The computer program embodied on a computer-readable medium as recited in claim 18 which additionally comprises seventh software for notifying each registered object, component or assembly that another object, component or assembly to which it is collaboratively linked has been changed and for automatically updating each linked, but not yet changed collaborated object, component or assembly.

22. A method of creating collaborative relationships between objects, components or assemblies thereof that are part of one or more applets, which are resident on a hardware based server, utilizing a collaborative application server that is also resident on the hardware based server, said method comprising:

registering each object, component or assembly for which collaboration is desired with the application server as a registered object;

building a record within the application server of each of the registered objects;

receiving change information from at least one of the registered objects when the at least one registered object has been changed; and

notifying at least one other of the registered objects, which is in a collaborative relation with the at least one registered object, that the at least one registered object has been changed.
