Abstract

A service interface enables an application to be developed independently from a particular service. At execution of the application, the application is wrapped or bound to a service. Advantageously, a configuration file includes instructions that bind particular applications with a particular service. Therefore, if improved services are developed after the application is written, only the configuration file needs to be updated, not the application source code. Accordingly, significant time and expense is saved by allowing applications to be developed independently from particular services.

Claims

1. A job processing framework comprising:

a job for execution;

a configuration source comprising instructions for specifying relationships between jobs and services; and

a service interface configured to bind the job at execution to a service by accessing the configuration source.

2. A job processing framework in accordance with claim 1 further comprising:

a pool of resources comprising a plurality of resource instances; and

a resource manager configured to assign a resource instance to the job for execution.

3. A job processing framework in accordance with claim 2 wherein said resource manager is further configured to add and remove resource instances and to propagate events in the resource pool.

4. A job processing framework in accordance with claim 2 wherein each of said plurality of resource instances comprises creatable resources.

5. A job processing framework in accordance with claim 2 wherein each of said plurality of resource instances comprises a timeout association.

6. A job processing framework in accordance with claim 2 wherein each of said plurality of resource instances comprises a refresh mechanism to preempt removal.

7. A job processing framework in accordance with claim 6 wherein each of said plurality of resource instances further comprises event propagation responsive to said refresh mechanism.

8. A job processing framework in accordance with claim 2 further including a resource timer configured to time resources to prevent loss of resources.

9. A job processing framework in accordance with claim 2 wherein ones of said plurality of resource instances comprise a thread as a resource.

10. A program for execution by a computer, said program instructing said computer to perform actions comprising:

receiving a job for execution;

accessing a configuration source to associate the job with a service; and

binding the job to the service at execution.

11. A program in accordance with claim 10 further comprising:

receiving a resource for executing the job.

12. A program in accordance with claim 10 wherein accessing a configuration source to associate the job with a service comprises accessing a configuration source to associate the job with one of a plurality of services.
