Abstract

A system having an Object Distributor and Integrator creates distributed software objects from non-distributed objects developed in different programming languages without requiring a human to explicitly program the objects with code specific to making the objects distributed, wherein the objects are of the type (but not restricted to) .dll, .class, or .obj. The Object Distributor and Integrator also provides integration of the objects with distribution specific code, with the distributed environment, dynamically and at runtime, without having to code reprogram the objects with code specific to the integration. The system may employ a method for dynamically distributing and integrating one or more non-distributed objects, including publisher objects and subscriber objects in a distributed environment. Generally, the method includes the steps of selecting at least one method of the non-distributed object, generating distribution code to enable the distribution of the object, and integrating the object in the distributed environment.

Claims

1. A system for distributing a non-distributed computer code object having at least one public method in a distributed environment having middleware, the system comprising:

a) a server configured to extract at least one method corresponding to the object in the distributed computing environment;

b) the server further configured to generate distribution code to enable the distribution of the object; and

,

c) the server further configured to generate integration code specific to the middleware onto which the object is integrated.

2. The system of claim 1, wherein the object is deployed as a publisher.

3. The system of claim 1, wherein the object is deployed as a subscriber.

4. The system of claim 3, wherein the server is configured to generate subscription specific code for the subscriber object, including method invocation code for subscribed methods of the publishers to which the subscriber object is subscribed, and the implementation of the Publisher'"'"'s Java Interface.

5. The system of claim 1, wherein the server is configured to publish at least one method.

6. The system of claim 1, wherein the server is configured to allow the subscription of at least one method.

7. The system of claim 1, wherein the extracted method is made public by the object.

8. The system of claim 1, wherein the object is a Java program having a plurality of public methods, and the server is further configured to

a) extract the plurality of public methods of the object;

b) allow for the selection of at least one of the extracted public method; and

c) publish the selected extracted public method.

9. The system of claim 1, wherein the server is further configured to:

a) extract a plurality of public methods of at least one publisher object from a repository of middleware;

b) allow for the selection of at least one of the extracted public method; and

c) subscribe at least one subscribing object to the selected extracted public method.

10. The system of claim 9, wherein the configuration of the server to extract a plurality of public methods further comprises the server configured to:

a) locate and read the repository;

b) extract a list of publishers and published methods corresponding to the list of publishers from the repository;

c) prepare a storage object that stores the extracted contents of the repository; and

d) display the extracted contents of the repository from the storage object for selection by a user.

11. The system of claim 9, wherein the configuration of the server to allow for the selection of at least one of the extracted public method further comprises the server configured to:

a) display a plurality of public methods to a user;

b) allow the user to select at least one method from the displayed plurality of public methods through a user interface; and

c) prepare a storage object that stores the selected method.

12. The system of claim 9, wherein the repository is located remotely from the server.

13. The system of claim 1, wherein the object is in native binary code and the server is further configured to translate native binary code into Java bytecode.

14. The system of claim 13, wherein the configuration of the server to translate native binary code into Java bytecode further includes the server configured to generate a computer program containing an implementation of the object'"'"'s published methods in C++ language and to generate a Java Native Interface implementation program in Java, containing the implementation of the object'"'"'s published methods in C++ language.

15. The system of claim 1, wherein the object is a publisher object having published methods, and the configuration of the server to generate distribution code further comprises the server configured to:

a) generate a Java Interface containing the published methods; and

b) generate a Java implementation program, implementing the generated Java Interface, and containing a Remote Method Invocation Mechanism.

16. A method for dynamically distributing and integrating a non-distributed object in a distributed environment comprising the steps of:

a) selecting at least one method of the non-distributed object;

b) generating distribution code to enable the distribution of the object; and

,

c) integrating the object in the distributed environment.

17. The method of claim 16, where the object is deployed as publisher object having public methods available for use by subscriber objects.

18. The method of claim 16, where the object is deployed as subscriber object.

19. The method of claim 16, wherein the object comprises a plurality of objects comprising subscriber objects and publisher objects.
