Abstract

A computer implemented method, system, and computer program product for generating a response to a web service request from a requester. In response to receiving a web service request, a web service controller calls a business logic interface associated with the request. The output of the business logic interface can either be obtained from a cache or derived from the business logic interface. A customizable template is executed to generate the response to the request. A determination is made as to whether the response comprises a set of cacheable content. In response to determining that the response comprises a set of cacheable content, the set of cacheable content is stored in the cache. The response is sent to the requester.

Claims

1. A computer implemented method for generating a response to a web service request from a requester, the computer implemented method comprising:

responsive to receiving a web service request, calling a business logic interface associated with the request;

executing a customizable template to generate the response to the request;

determining whether the response comprises a set of cacheable content;

responsive to a determination that the response comprises a set of cacheable content, storing the set of cacheable content in the cache; and

sending the response to the requester.

2. The computer implemented method of claim 1 wherein an output of the business logic interface is obtained from at least one of a cache, and derived from the business logic interface.

3. The computer implemented method of claim 1 wherein the executing of a customizable template step further comprises:

determining whether the response is cacheable;

responsive to determining the response is cacheable, identifying a set of cached content in the cache, wherein the cached content is responsive to the request; and

retrieving the identified set of cached content, wherein the response comprises the identified set of cached content.

4. The computer implemented method of claim 3 further comprising:

executing a set of template fragments to generate a set of dynamic content, wherein the set of dynamic content forms a dynamic portion of the response, and wherein the response comprises the set of cached content and the set of dynamic content.

5. The computer implemented method of claim 1 wherein the customizable template is not executed responsive to a determination that a complete response to the request is stored in the cache.

6. The computer implemented method of claim 1 wherein the business logic interface is an application programming interface associated with a web service application, and the response is generated based upon the output of the application programming interface.

7. The computer implemented method of claim 1 further comprising:

mapping the web service request onto a web service application to generate a call on the business logic interface.

8. The computer implemented method of claim 1 wherein the output of the business logic interface is stored in the cache responsive to a determination that the output is cacheable.

9. The computer implemented method of claim 1 further comprising:

modifying a content of the response by updating a text file representing the customizable template.

10. The computer implemented method of claim 1 wherein a caching policy specifying caching of the response is modified by updating a text file representing the template.

11. The computer implemented method of claim 1 wherein the cacheable content is stored in the cache in accordance with a fragment caching approach.

12. A computer program product comprising:

a computer usable medium including computer usable program code for generating a response to a web service request from a requester, said computer program product comprising;

computer usable program code responsive to receiving a web service request, for calling a business logic interface associated with the request;

computer usable program code for executing a customizable template to generate the response to the request;

computer usable program code for determining whether the response comprises a set of cacheable content; and

computer usable program code for storing the set of cacheable content in the cache in response to determining that the response comprises a set of cacheable content;

computer usable program code for sending the response to the requester.

13. The computer program product of claim 12 wherein an output of the business logic interface is obtained from at least one of a cache, and derived from the business logic interface.

14. The computer program product of claim 12 further comprising:

computer usable program code for determining whether the response is cacheable;

computer usable program code for identifying a set of cached content in the cache in response to determining that the response is cacheable, wherein the cached content is responsive to the request; and

computer usable program code for retrieving the identified set of cached content, wherein the response comprises the identified set of cached content.

15. The computer program product of claim 14 further comprising:

computer usable program code for executing a set of template fragments to generate a set of dynamic content, wherein the set of dynamic content forms a dynamic portion of the response, and wherein the response comprises the set of cached content and the set of dynamic content.

16. The computer program product of claim 12 wherein the customizable template is not executed responsive to a determination that a complete response to the request is stored in the cache.

17. The computer program product of claim 12 wherein the cacheable content is stored in the cache in accordance with a fragment caching approach.

18. The computer program product of claim 12 further comprising:

computer usable program code for modifying a content of the response by updating a text file representing the customizable template.

19. The computer program product of claim 12 wherein a caching policy specifying caching of the response is modified by updating a text file representing the template.

20. A system for generating a response to a web service request from a requestor, comprising:

a web service controller, wherein the web service controller calls a business logic interface associated with the request in response to receiving the web service request, and wherein an output of the interface can be obtained from at least one of a cache, and derived from the interface;

a response building engine, wherein the response building engine executes a customizable template to generate the response to the request;

determine whether the response comprises a set of cacheable content;

store the set of cacheable content in the cache in response to determining that the response comprises a set of cacheable content; and

a web service runtime, wherein the web service runtime sends the response to the requester.
