Abstract

A method for a first process in a first address space to communicate with an object in a second address space including the steps of determining, during runtime of the first process, that a communication link is needed between the first process and a target object in the second address space, generating a proxy object in the first address space corresponding to the target object, and establishing the communication link between the first process and the target object through the proxy object. In addition, an apparatus for a first process in a first address space to communicate with an object in a second address space including apparatus for determining, during runtime of the first process, that a communication link is needed between the first process and a target object in the second address space, apparatus for generating a proxy object in the first address space corresponding to the target object, and apparatus for establishing the communication link between the first process and the target object through the proxy object.

Claims

1. A method for a first process in a first address space to communicate with an object in a second address space comprising the computer implemented steps of:

a) determining, during run time of the first process, that a requested communication link needed by the first process is needed with a target object located in the second address space;

b) generating a proxy object in the first address space corresponding to the target object, said generated proxy object emulating said target object in the first address space; and

c) establishing the communication link between the first process and the target object through the proxy object.

2. The method of claim 1 further comprising a step of locating said target object.

3. The method of claim 1 wherein the step of establishing includes establishing the communication link across a network between host systems.

4. The method of claim 1 further comprising a step of communicating between said first process and said target object through said proxy object.

5. An apparatus in a computer system for a first process in a first address space to communicate with an object in a second address space comprising:

a) means for determining, during runtime of the first process, that a requested communication link needed by the first process is needed with a target object located in the second address space;

b) means for generating a proxy object in the first address space corresponding to the target object, said generated proxy object emulating the target object in the first address space; and

c) means for establishing the communication link between the first process and the target object through the proxy object.

6. The apparatus of claim 5 further comprising means for locating said target object.

7. The apparatus of claim 5 wherein the means for establishing includes means for establishing the communication link across a network between host systems.

8. The apparatus of claim 5 further comprising means for communicating between said first process and said target object through said proxy object.

9. A data processing system for a first process in a first address space to communicate with an object in a second address space comprising:

a) means for storing data to be processed;

b) means for processing data;

c) means for determining, during runtime of the first process, that a requested communication link needed by the first process is needed with a target object located in the second address space;

d) means for generating a proxy object in the first address space corresponding to the target object, said generated proxy object emulating the target object in the first address space; and

e) means for establishing the communication link between the first process and the target object through the proxy object.

10. The data processing system of claim 9 further comprising means for locating said target object.

11. The data processing system of claim 9 wherein the means for establishing includes means for establishing the communication link across a network between host systems.

12. The data processing system of claim 9 further comprising means for communicating between said first process and said target object through said proxy object.

13. A computer program product stored in computer memory executable by a processor in a computer system for a first process in a first address space to communicate with an object in a second address space comprising:

a) means for determining, during runtime of the first process, that a requested communication link needed by the first process is needed with a target object located in the second address space of said computer system;

b) means for generating a proxy object in the first address space of said computer system corresponding to the target object, said generated proxy object emulating the target object in the first address space; and

c) means for establishing the communication link between the first process and the target object through the proxy object.

14. The computer program product of claim 13 further comprising means for locating said target object.

15. The computer program product of claim 13 wherein the means for establishing includes means for establishing the communication link across a network between host systems.

16. The computer program product of claim 13 further comprising means for communicating between said first process and said target object through said proxy object.
