Abstract

A computer-controlled method can include providing a resource adapter with an object wrapper having a plurality of features, a wrapper generation tool receiving a change to be made to the object wrapper, and the wrapper generation tool generating a new object wrapper based on the change. The resource adapter can receive an object from a messaging provider, adapt the object based on the newly generated object wrapper, and send the wrapped object to an application.

Claims

1. A computer-controlled method, comprising:

providing a resource adapter with access to at least one object wrapper in a wrapper library, the at least one object wrapper comprising a plurality of features;

a wrapper generation tool receiving at least one change to be made to at least one of the plurality of features of the at least one object wrapper;

the wrapper generation tool determining whether it can generate a new object wrapper based on the at least one change to at least one of the plurality of features of the at least one object wrapper;

responsive to a determination that the wrapper generation tool can generate the new object wrapper based on the at least one change to at least one of the plurality of features of the at least one object wrapper, the wrapper generation tool generating the new object wrapper based on the at least one change;

responsive to a determination that the wrapper generation tool cannot generate the new object wrapper based on the at least one change to at least one of the plurality of features of the at least one object wrapper, the wrapper generation tool notifying an administrator that the at least one of the plurality of features cannot be used;

the resource adapter receiving an object from a first messaging provider;

the resource adapter encapsulating the received object with the newly generated object wrapper; and

the resource adapter sending the wrapped object to an application.

2. The computer-controlled method of claim 1, wherein the application is managed by an application server.

3. The computer-controlled method of claim 2, wherein the application resides on the application server.

4. The computer-controlled method of claim 1, further comprising the wrapper generation tool generating a plurality of new object wrappers based on the at least one change.

5. The computer-controlled method of claim 1, further comprising:

a company using the wrapper generation tool to generate a plurality of wrappers, each of which is specific to one of a plurality of messaging providers, the plurality of messaging providers including the first messaging provider; and

the company supplying said plurality of wrappers for use with the resource adapter and the plurality of messaging providers.

6. The computer-controlled method of claim 1, further comprising:

a customer using the wrapper generation tool to generate wrappers specific to at least one messaging provider that the customer uses, the at least one messaging provider including the first messaging provider.

7. The computer-controlled method of claim 1, further comprising:

a third-party using the wrapper generation tool to generate a plurality of wrappers, each of which is specific to one of a plurality of messaging providers, the plurality of messaging providers including the first messaging provider; and

the third-party supplies said plurality of wrappers for use with its messaging provider and the resource adapter.

8. The computer-controlled method of claim 1, wherein the object is one of a group consisting of the following:

a message, a topic, a queue, a connection, a producer, a session, or a consumer.

9. The computer-controlled method of claim 1, wherein the at least one change comprises a new header.

10. The computer-controlled method of claim 1, wherein the at least one change comprises at least one new field.

11. The computer-controlled method of claim 1, wherein the at least one object wrapper comprises a plurality of distinct classes.

12. The computer-controlled method of claim 11, wherein the at least one object wrapper further comprises a plurality of extensions.

13. The computer-controlled method of claim 1, wherein the at least one object wrapper is specific to at least one from a group of message types consisting of the following:

bytes, map, object, stream, and text.

14. The computer-controlled method of claim 1, further comprising the application using the wrapped object.

15. The computer-controlled method of claim 14, wherein using the wrapped object comprises the application invoking a method on the wrapped object.

16. The computer-controlled method of claim 14, wherein using the wrapped object comprises the application casting the wrapped object to a messaging provider-specific interface.

17. One or more non-transitory computer-readable media storing instructions that, when executed by a processor, cause the processor to perform the method of:

providing a resource adapter with access to at least one object wrapper in a wrapper library, the at least one object wrapper comprising a plurality of features;

a wrapper generation tool receiving at least one change to be made to at least one of the plurality of features of the at least one object wrapper;

the wrapper generation tool determining whether it can generate a new object wrapper based on the at least one change to at least one of the plurality of features of the at least one object wrapper;

responsive to a determination that the wrapper generation tool can generate the object wrapper based on the at least one change to at least one of the plurality of features of the at least one object wrapper, the wrapper generation tool generating the new object wrapper based on the at least one change;

responsive to a determination that the wrapper generation tool cannot generate the new object wrapper based on the at least one change to at least one of the plurality of features of the at least one object wrapper, the wrapper generation tool notifying an administrator that the at least one of the plurality of features cannot be used;

the resource adapter receiving an object from a first messaging provider;

the resource adapter encapsulating the received object with the newly generated object wrapper; and

the resource adapter sending the wrapped object to an application.

18. A system, comprising:

a first device hosting a messaging service configured to provide an object;

a second device hosting an application;

a third device hosting a resource adapter and having a processor that is configured to cause the resource adapter to receive at least one object wrapper comprising a plurality of features and further configured to cause the resource adapter to receive the object from the first device; and

a fourth device hosting a wrapper generation tool configured to receive at least one change to be made to at least one of the plurality of features of the at least one object wrapper and further configured to determine whether it can generate a new object wrapper based on the at least one change to at least one of the plurality of features of the at least one object wrapper, generate the new object wrapper based on the at least one change responsive to a determination that the wrapper generation tool can generate the new object wrapper based on the at least one change to at least one of the plurality of features of the at least one object wrapper, and notify an administrator that the at least one of the plurality of features cannot be used responsive to a determination that the wrapper generation tool cannot generate the new object wrapper based on the at least one change to at least one of the plurality of features of the at least one object wrapper, wherein the resource adapter is further configured to encapsulate the received object with the newly generated object wrapper and subsequently send the wrapped object to the application.

19. The system of claim 18, wherein the third and fourth devices are a single machine.

20. The system of claim 18, wherein the second and third devices are a single machine.

21. The system of claim 18, wherein the first and second devices are a single machine.

22. The system of claim 18, wherein the second device is an application server.

23. The system of claim 18, wherein the third device is an enterprise server.
