Abstract

A dynamic CORBA gateway allows CORBA services to be exposed to non-CORBA clients and non-CORBA services to be exposed to CORBA clients over a Simple Object Access Protocol (SOAP) with a SOAP upstream and downstream interface and Virtual CORBA Service Object.

Claims

1. A method of communicating within a distributed object oriented computing system comprising the step of:

exposing a service that is not specified through a Common Object Request Broker Architecture (CORBA) to a client that is CORBA specified using a Simple Object Access Protocol (SOAP) message, wherein the method further comprises the step of creating and maintaining references to Virtual CORBA services via a Virtual CORBA Service Object as part of a dynamic CORBA (gateway that includes at least one Business/Logic Protocol Adapter having interactive scripting for preparing SOAP requests that are transmitted over the CORBA gateway through a SOAP upstream interface operable with the CORBA gateway and a downstream interface operable for communicating with dynamic modules for service implementation as CORBA objects.

2. A method according to claim 1, and further comprising the step of preparing a SOAP request by interactive scripting as part of a client business logic function and operable via a SOAP interface.

3. A method according to claim 1, and further comprising the step of addressing the Virtual CORBA services by a set of HTTP Uniform Resource Locators (URL'"'"'s).

4. A method according to claim 3, wherein the references can be exposed as a monolithic CORBA service.

5. A method according to claim 1, and further comprising the step of serializing CORBA Name Value list data types to SOAP messages.

6. A method of communicating within a distributed object oriented computing system comprising the steps of:

exposing a service that is not specified through a Common Object Request Broker Architecture (CORBA) to a client that is CORBA specified using a Simple Object Access Protocol (SOAP) message; and

implementing Internet Inter-ORB Protocol (IIOP) callbacks using Simple Object Access Protocol (SOAP), wherein the method further comprises the step of creating and maintaining references to virtual CORBA services via a Virtual CORBA Service Object as part of a dynamic CORBA gateway that includes at least one Business/Logic Protocol Adapter having interactive scripting for preparing SOAP requests that are transmitted over the CORBA gateway through a SOAP upstream interface operable with the CORBA gateway and a downstream interface operable for communicating with dynamic modules for service implementation as CORBA objects.

7. A method according to claim 6, and further comprising the step of addressing the Virtual CORBA services by a set of HTTP Uniform Resource Locators (URL'"'"'s).

8. A method according to claim 7, wherein the references can be exposed as a monolithic CORBA service.

9. A method according to claim 6, and further comprising the step of serializing CORBA Name Value list data types to SOAP messages.

10. A method of communicating within a distributed object oriented computing system comprising the step of:

exposing a service that is not specified through a Common Object Request Broker Architecture (CORBA) to a client that is CORBA specified using a Simple Object Access Protocol (SOAP) message;

translating Interface Definition Language (IDL) method calls to the SOAP messages; and

transmitting to a specified method implementation HTTP Uniform Resource Locator (URL) via a Virtual CORBA Service Object that forms a CORBA gateway having virtual CORBA services, wherein the method further comprises the step of creating and maintaining references to virtual CORBA services via the Virtual CORBA Service Object as part of a dynamic CORBA gateway that includes at least one Business/Logic Protocol Adapter having interactive scripting for preparing SOAP requests that are transmitted over the CORBA gateway through a SOAP upstream interface operable with the CORBA gateway and a downstream interface operable for communicating with dynamic modules for service implementation as CORBA objects.

11. A method according to claim 10, and further comprising the step of addressing the Virtual CORBA services by a set of HTTP Uniform Resource Locators (URL'"'"'s).

12. A method according to claim 11, wherein the references can be exposed as a monolithic CORBA service.

13. A method according to claim 10, and further comprising the step of serializing CORBA Name Value list data types to SOAP messages.

14. A distributed object computing system comprising:

a service that is not specified through a Common Object Request Broker Architecture (CORBA);

a client that is CORBA specified;

a CORBA gateway having a Simple Object Access Protocol (SOAP) interface and Virtual CORBA Service Object through which the service that is not specified through CORBA is exposed to the client that is CORBA specified;

a SOAP upstream interface operable with the CORBA gateway;

a SOAP downstream interface operable for communicating with dynamic modules for service implementation as CORBA objects; and

wherein the Virtual CORBA Service Object is operable to create and maintain references to virtual CORBA services, said CORBA gateway further comprising at least one Business/Logic Protocol Adapter having interactive scripting for preparing SOAP requests that are transmitted over the CORBA gateway through the SOAP upstream interface and the downstream interface operable for communicating with dynamic modules for service implementation as CORBA objects.

15. A distributed object computing system according to claim 14, and further comprising a Dynamic Client Business Logic function operative with an Internet Inter-ORB Protocol (IIOP) callback using a SOAP message.

16. A distributed object computing system according to claim 14, wherein said Virtual CORBA Service Object is operative as a Portable Object Adapter.

17. A distributed object computing system according to claim 14, and further comprising a serializer for serializing CORBA Name Value list data types to SOAP messages.

18. A distributed object computing system according to claim 14, wherein said CORBA gateway is operative for translating Interface Definition Language method calls to SOAP messages.
