Abstract

A method, apparatus and computer-usable medium for using wildcards in a JMS Topic name. The method includes the steps of sending to a Java Naming and Directory Interface (JNDI) a storage message for messages that are identified by an identifier that includes a topic stock identifier and a topic wildcard indicator; and sending an implementation message from the JNDI to a middleware instructing the middleware to store new messages in any topic having the topic stock identifier. The implementation message causes the middleware to create a special topic that includes the topic stock identifier and the topic wildcard indicator, a query of all topics that include the topic stock identifier, and a generation of a reusable dynamic message flow instruction to a broker to direct future new messages from a publisher to all topics having the topic stock identifier.

Claims

1. A computer-implementable method comprising:

sending to a Java Naming and Directory Interface (JNDI) a storage request for topics that are identified by an identifier that includes a topic stock identifier and a topic wildcard indicator; and

sending an implementation message from the JNDI to a middleware instructing the middleware to store new messages in any topic having the topic stock identifier, wherein the implementation message causes;

the middleware to create a special topic that acts as an entry point to a generated dynamic flow,

a query of all topics that include the topic stock identifier, and

a generation of a reusable dynamic message flow instruction to a broker to direct, in the future, a copy of relevant new messages from a publisher to each of the topics having the topic stock identifier.

2. The computer-implementable method of claim 1, further comprising:

sending a request from a Java Messaging Service (JMS) publisher to a broker, thus causing execution of the dynamically generated flow.

3. A system comprising:

a processor;

a data bus coupled to the processor; and

a computer-usable medium embodying computer program code, the computer-usable medium being coupled to the data bus, the computer program code comprising instructions executable by the processor and configured for;

sending to a Java Naming and Directory Interface (JNDI) a storage request for topics that are identified by an identifier that includes a topic stock identifier and a topic wildcard indicator; and

sending an implementation message from the JNDI to a middleware instructing the middleware to store new messages in any topic having the topic stock identifier, wherein the implementation message causes;

the middleware to create a special topic that acts as an entry point to a generated dynamic flow,

a query of all topics that include the topic stock identifier, and

a generation of a reusable dynamic message flow instruction to a broker to direct, in the future, a copy of relevant new messages from a publisher to each of the topics having the topic stock identifier.

4. The system of claim 3, wherein the instructions are further configured for:

sending a request from a Java Messaging Service (JMS) publisher to a broker, thus causing execution of the dynamically generated flow.

5. A computer-usable medium embodying computer program code, the computer program code comprising computer executable instructions configured for:

sending to a Java Naming and Directory Interface (JNDI) a storage request for topics that are identified by an identifier that includes a topic stock identifier and a topic wildcard indicator; and

sending an implementation message from the JNDI to a middleware instructing the middleware to store new messages in any topic having the topic stock identifier, wherein the implementation message causes;

the middleware to create a special topic that acts as an entry point to a generated dynamic flow,

a query of all topics that include the topic stock identifier, and

a generation of a reusable dynamic message flow instruction to a broker to direct, in the future, a copy of relevant new messages from a publisher to each of the topics having the topic stock identifier.

6. The computer-usable medium of claim 5, wherein the embodied computer program code further comprises computer executable instructions configured for:

sending a request from a Java Messaging Service (JMS) publisher to a broker, thus causing execution of the dynamically generated flow.

7. The computer-useable medium of claim 5, wherein the computer executable instructions are deployable to a client computer from a server at a remote location.

8. The computer-useable medium of claim 5, wherein the computer executable instructions are provided by a service provider to a customer on an on-demand basis.
