Abstract

The present invention is generally directed to a method, system, and article of manufacture that provides an internationalization service in a generalized message-oriented middleware system. In one embodiment, the internationalization handler for the MOM messages exists on both the message-producing and the message-consuming sides. The front-end server and back-send server application containers pass control to the internationalization handlers at predefined points during message production and consumption. On the message production side, the message producer passes control to the internationalization handler after the creation of the MOM message is complete but before the message is dispatched by the MOM for routing and delivery. On the message consumption side, the back end application passes control to the consumer side JMS internationalization handler just before invoking an “onMessage” method or similar message listener method. Some embodiments may also include a reply indicator to indicate whether or not the message is a reply to a service request.

Claims

1. A method for providing internationalization context in a messaging middleware environment, comprising:

generating a message;

attaching an internationalization context to the message; and

sending the message with the internationalization context to a messaging facility.

2. The method of claim 1, further comprising:

receiving a request to generate the message; and

determining the internationalization context associated with a thread on which the request is executing.

3. The method of claim 2, wherein the internationalization context is determined using a table that associates the internationalization context with the thread.

4. The method of claim 1, wherein the internationalization context is an invocation internationalization context.

5. The method of claim 1, further comprising:

receiving the message from a message oriented middleware environment; and

extracting the internationalization context from the message.

6. The method of claim 5, further comprising associating the internationalization context with a thread of execution.

7. The method of claim 1, wherein the message comprises a header and a body, and wherein attaching the internationalization context to the message comprises inserting locale information and time zone information into the header.

8. The method of claim 7, wherein the locale information comprises one or more properties chosen from the group consisting of a language identifier, a country identifier, and a variant string.

9. The method of claim 1, further comprising attaching a reply indicator to the message

10. A method for providing internationalization context in a messaging middleware environment, comprising:

receiving the message having an internationalization context;

extracting an internationalization context from the message;

storing the internationalization context to a table that associates the internationalization context with the thread upon which service request is dispatched.

11. The method of claim 10, wherein the message further comprises a service request.

12. The method of claim 11, further comprising processing the service request according to the internationalization context.

13. The method of claim 12, wherein processing the service request according to the internationalization context comprises generating a reply to the service request.

14. The method of claim 13, wherein the message further comprises a reply indicator.

15. The method of claim 14, wherein processing the service request according to the internationalization context comprises using the reply indicator to select an internationalization context.

16. The method of claim 10, further comprising:

generating a message containing the reply to the service request;

attaching an internationalization context to the message; and

sending the message with the internationalization context to a messaging facility.

17. The method of claim 10, further comprising selecting a default value if the internationalization context does not contain an internationalization attribute.

18. The method of claim 16, wherein selecting a default value comprises selecting the default value associated with the lowest level entity for which a default value is available.

20. The computer program product of claim 18, wherein the signal bearing media comprises a transmission medium.

21. The computer program product of claim 18, wherein the signal bearing media comprises a non-writable storage media.

23. The method of claim 21, wherein the message context comprises an internationalization context.

25. The method of claim 21, further comprising using a default value to generate the reply indicator.

27. The method of claim 21, further comprising using a managed messaging environment call to generate the reply indicator.

28. The method of claim 21, wherein the reply indictor is specified programmatically.

30. The system of claim 28, further comprising a publisher that publishes a new message to the topic, wherein the new message includes an internationalization property.

19. A computer program product, comprising:

(a) a program which, when executed by a processor, performs a method of sending a message from a message-producing client to a message-consuming client, the method comprising;

generating a header having an internationalization context of the message-producing client;

attaching the header to a message; and

sending the message with the internationalization header to the message-consuming client; and

(b) a signal bearing media bearing the program.

22. A method for managing message context in a messaging middleware environment, comprising:

generating a message having a message context;

attaching a reply indicator to the message; and

sending the message with the reply indicator.

24. The method of claim 22, wherein the message context comprises a security context.

26. The method of claim 24, wherein the default value is specified within an external descriptor.

29. A message oriented middleware system, comprising:

a subscriber to a topic, the topic comprising a plurality of messages having internationalization properties; and

a message oriented middleware system adapted to send a subset of the plurality of messages in the topic to the subscriber in accordance with a selection criteria, wherein the selection criteria comprises an internationalization context.
