Abstract

Embodiments of the present invention enable a server to respond to a service request from a client with a “get the request” type of response first instead of an actual and immediate response, which will be sent later asynchronously in a separate message when the response becomes available at the service provider. Alternatively, the service provider may also send the actual response to an intermediary Web service, which will translate the response into a format acceptable by the client before relaying it to the client. This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.

Claims

1. A system to provide asynchronous request response, comprising:

a client operable to;

submit a service request for Web service to a service provider; and

accept a response from the Web service; and

said service provider operable to;

acknowledge the receipt of the service request from the client;

wait for the response from the Web service to become available; and

send the response asynchronously to the client.

2. The system according to claim 1, wherein:

the client is a Web service.

3. The system according to claim 1, further comprising:

an intermediary service operable to;

accept the response from the Web service;

translate the response into a format acceptable by the client; and

relay the translated response to the client.

4. The system according to claim 3, wherein:

the service provider is further operable to send the response to the intermediary service.

5. The system according to claim 3, wherein:

the client is further operable to accept the translated response from the intermediary service.

6. The system according to claim 3, wherein:

the intermediary service can reside on the same server as the client.

7. The system according to claim 3, wherein:

the intermediary service is an async response service.

8. The system according to claim 7, further comprising:

a handler chain that can be saved when the service request is submitted asynchronously.

9. The system according to claim 8, wherein:

the handler chain is saved in a persistent map.

10. The system according to claim 8, wherein:

the intermediary service is further operable to;

look up the handler chain saved; and

invoke it to bind the result.

11. A method to provide asynchronous request response, comprising:

submitting a service request for Web service to a service provider;

acknowledging the receipt of the service request from the client;

waiting for a response from the Web service to become available;

sending the response asynchronously to the client; and

accepting the response from the Web service.

12. The method according to claim 11, further comprising:

accepting the response from the Web service at an intermediary service;

translating the response into a format acceptable by the client; and

relaying the translated response to the client.

13. The method according to claim 12, further comprising:

sending the response to the intermediary service.

14. The method according to claim 12, wherein:

the intermediary service is an async response service.

15. The method according to claim 14, further comprising:

saving a handler chain when the service request is submitted asynchronously.

16. The method according to claim 15, further comprising:

saving the handler chain in a persistent map.

17. The method according to claim 15, further comprising:

looking up the handler chain saved; and

invoking it to bind the result.

18. A machine readable medium having instructions stored thereon that when executed cause a system to:

submit a service request for Web service to a service provider;

acknowledge the receipt of the service request from the client;

wait for a response from the Web service to become available;

send the response asynchronously to the client; and

accept the response from the Web service.

19. A system to provide asynchronous request response, comprising:

means for submitting a service request for Web service to a service provider;

means for acknowledging the receipt of the service request from the client;

means for waiting for a response from the Web service to become available;

means for sending the response asynchronously to the client; and

means for accepting the response from the Web service.
