Abstract

A method for asynchronously retrieving information. Such a method may include: invoking a process in a subscribing server; registering, by the process, an event request with an event server; requesting, by the process over a first connection, resource information from a originating server, the first connection being disconnected after the requesting; receiving, by the event server over a second connection, event information from the originating server, the second connection disconnected after the receiving; and tranforming, to the process from the event server, the event information.

Claims

1. A method for asynchronously retrieving information comprising:

invoking a process in a subscribing server;

registering, by the process, an event request with an event server;

requesting, by the process over a first connection, resource information from a originating server, the first connection being disconnected after the requesting;

receiving, by the event server over a second connection, event information from the originating server, the second connection disconnected after the receiving; and

transferring, to the process from the event server, the event information.

2. The method of claim 1 further comprising:

listening by the process to the event server for the availability of the event information.

3. The method of claim 1 further comprising:

categorizing an event request into an event type to aid in the processing of the request.

4. The method of claim 1 wherein,

the first and second connections occur over remote method invocation connections.

5. A system for asynchronously retrieving information comprising:

means for invoking a process in a subscribing server;

means for registering by the process an event request with an event server;

means for requesting by the process, over a first connection, event information from an originating server;

means for disconnecting the first connection after requesting the event information;

means for receiving by the event server, over a second connection, the event information from the originating server;

means for disconnecting the second connection after receiving the event information; and

means for transferring to the process from the event server, the event information.

6. The system of claim 5 further comprising:

means for listening by the process to the event server for the availability of the event information;

7. The system of claim 5 further comprising:

means for categorizing an event request into an event type to aid in the processing of the request.

8. The system of claim 5 further comprising:

means for connecting the process to the originating server using a remote method invocation connection.

9. The system of claim 5 further comprising:

means for assigning an identification value to the event request.

10. A system for asynchronously retrieving information comprising:

an originating server;

a subscribing server that invokes a process wherein the process registers an event request with an event server of the subscribing server;

the process further requests resource information from the originating server using a first connection;

the event server receives event information from the originating server using a second connection, and transfers to the process the event information, the first connection and the second connection being terminated after an event is registered and event information is transferred, respectively.

11. The system of claim 10 further comprising wherein the process listens to the event server for the availability of the event information;

12. The system of claim 10 wherein the subscribing server further categorizes an event request into an event type to aid in the processing of the request.

13. The system of claim 10 wherein the subscribing server further connects the process to the originating server using a remote method invocation connection.

14. The system of claim 10 wherein the subscribing server further assigns an identification value to the event request.

15. A machine readable medium including instructions that instruct a computing device, the instructions comprising:

invoking a process in a subscribing server;

registering, by the process, an event request with an event server;

requesting, by the process over a first connection, event information from a originating server, the first connection being disconnected after the requesting;

receiving, by the event server over a second connection, event information from the originating server, the second connection being disconnected after the receiving; and

transferring to the process from the event server, the event information.

16. The instructions of claim 15 further comprising:

listening by the process to the event server for the availability of the event information;

17. The instructions of claim 15 further comprising:

categorizing an event request into an event type to aid in the processing of the request.

18. The instructions of claim 15 further comprising:

connecting the process to the originating server using a remote method invocation connection.

19. The instructions of claim 15 further comprising:

assigning an identification value to the event request.

20. A system for asynchronously retrieving information comprising:

a subscribing server,

a originating server that uses an event server to receive and handle an event request over a first connection from the subscribing server, transfers event information from a process to the event server, and forwards over a second connection the event information to the subscribing server via the event server.

21. A method of asynchronously retrieving information comprising:

receiving, by a first server, a request for a event information from a client;

sending a request over a first connection to a second server to provide the resource, the first connection being disconnected after the sending;

receiving from the second server, over a second connection, event information, the second connection being disconnected after the receiving;

sending a portion of the resource event information to the client.
