Abstract

A method for prioritizing web service requests in a web service container is provided. The method includes receiving a web service request, identifying a web service requested by the web service request, determining any parameter of the web service request, determining a priority for the web service request and adding the web service request to a queue. The queue includes one or more web service requests, and the positions of the web service requests in the queue are arranged based on their respective priority. The web service requests in the queue are processed sequentially, thereby achieving prioritization of web service requests.

Claims

1. A method for prioritizing web service requests in a web service container, the method comprising:

receiving a web service request;

identifying a web service requested by the web service request;

determining at least one parameter of the web service request, if any;

determining a priority for the web service request; and

adding the web service request to a queue,

wherein the queue includes one or more web service requests, and the positions of the web service requests in the queue are arranged based on their respective priority, and

wherein the web service requests in the queue are processed sequentially, thereby achieving prioritization of web service requests.

2. The method of claim 1, wherein the processing of the web service requests in the queue comprises:

retrieving a web service request from the front of the queue;

invoking a web service requested by the retrieved web service request, wherein when at least one parameter associated with the retrieved web service request is determined, the web service is invoked by the retrieved web service request with the at least one parameter; and

returning a response from the invoked web service corresponding to the retrieved web service request.

3. The method of claim 1, further comprising assigning a thread from a thread pool for processing each of the web service requests in the queue.

4. The method of claim 1, wherein the priority for the web service request is determined based on business logics.

5. The method of claim 2, wherein the web service request is in accordance with the Simple Object Access Protocol (SOAP) and transported to the web service container over the HyperText Transfer Protocol (HTTP).

6. The method of claim 5, further comprising decoding the received web service request to determine information represented within the web service request.

7. The method of claim 6, wherein the web service requested by the web service request is determined from the information obtained from the decoded web service request.

8. The method of claim 5, wherein the determining of the at least one parameter of the web service request comprises deserializing the web service request.

9. The method of claim 5, further comprising serializing the response from the invoked web service into a response message in accordance with the Simple Object Access Protocol (SOAP) which is suitable to be transported to a client requesting the web service.

10. The method of claim 1, further comprising:

comparing the priority of the web service request with the priority of the web service request at the last position in the queue;

switching the position of the web service request with the last web service request if the priority of the web service request is higher than the priority of the last web service request; and

repeatedly comparing the priority of the web service request with the priority of a subsequent web service request in the queue, and switching the position of the web service request with the subsequent web service request if the priority of the web service request is higher than the priority of the subsequent web service request, until the priority of the subsequent web service request is higher than the priority of the web service request.

11. A web service container comprising:

an interceptor for receiving a web service request;

an identifier for identifying a web service requested by the web service request;

a determining unit for determining at least one parameter of the web service request, if any;

a priority calculation unit for determining a priority for the web service request; and

a priority queue for adding the web service request to a queue,

wherein the queue includes one or more web service requests, and the positions of the web service requests in the queue are arranged based on their respective priority, and

wherein the web service requests in the queue are processed sequentially, thereby achieving prioritization of web service requests.

12. The web service container of claim 11, further comprising a processing unit for processing the web service requests in the queue by:

retrieving a web service request from the front of the queue;

invoking a web service requested by the retrieved web service request, wherein when at least one parameter associated with the retrieved web service request is determined, the web service is invoked by the retrieved web service request with the at least one parameter; and

returning a response from the invoked web service corresponding to the retrieved web service request.

13. The web service container of claim 11, wherein the processing unit is a thread pool which assigns a thread for processing each of the web service requests in the queue.

14. The web service container of claim 11, wherein the priority calculation unit determines the priority for the web service request based on business logics.

15. The web service container of claim 12, wherein the web service request is in accordance with the Simple Object Access Protocol (SOAP) and transported to the web service container over the HyperText Transfer Protocol (HTTP).

16. The web service container of claim 15, wherein the interceptor is adapted to decode the received web service request to determine information represented within the web service request.

17. The web service container of claim 16, wherein the web service requested by the web service request is determined from the information obtained from the decoded web service request.

18. The web service container of claim 15, wherein the determining unit comprises a deserializer for deserializing the web service request to determine the at least one parameter of the web service request.

19. The web service container of claim 15, further comprising a serializer for serializing the response from the invoked web service into a response message specified in accordance with the Simple Object Access Protocol (SOAP) which is suitable to be transported to a client requesting the web service.

20. A program storage device readable by a computing device, tangibly embodying a program of instructions, executable by the computing device to perform a method for prioritizing web service requests in a web service container, the method comprising:

receiving a web service request;

identifying a web service requested by the web service request;

determining at least one parameter of the web service request, if any;

determining a priority for the web service request; and

adding the web service request to a queue,

wherein the queue includes one or more web service requests, and the positions of the web service requests in the queue are arranged based on their respective priority, and

wherein the web service requests in the queue are processed sequentially, thereby achieving prioritization of web service requests.
