Abstract

Provided are a method, system, and article of manufacture, wherein a client component including at least one client interface is provided. Also provided is a target component including at least one service interface, wherein the at least one client interface is capable of matching the at least one service interface. A service interface implementation corresponding to the at least one service interface is provided, wherein the service interface implementation is a dynamic service interface implementation. The dynamic service interface implementation is executed to allow access to the client component to a service provided by the target component.

providing a client component including at least one client interface;

providing a target component including at least one service interface, wherein the at least one client interface is capable of matching the at least one service interface;

providing a service interface implementation corresponding to the at least one service interface, wherein the service interface implementation is a dynamic service interface implementation; and

executing the dynamic service interface implementation to allow access to the client component to a service provided by the target component.

2. The method of claim 1, wherein the client component further comprises a reference that is typed by the at least one client interface that matches the service interface of the target component, wherein an implementation of the target component is not exposed to the client component, wherein the service component implements defined interfaces, and wherein the client component accesses the target component.

3. The method of claim 1, wherein the dynamic service interface implementation is of an asynchronous variant.

4. The method of claim 1, wherein the dynamic service interface implementation is of a synchronous variant.

5. The method of claim 1, wherein the service interface implementation is a static service interface implementation of an asynchronous variant.

6. The method of claim 1, wherein the service interface implementation is a static service interface implementation of a synchronous variant.

7. The method of claim 1, wherein the service interface implementation is the dynamic service implementation if the at least one service interface and the service interface implementation are coded in different computer languages, wherein the client interface is coded in a first computer language and the at least one service interface in the target component is coded in a second computer language.

8. The method of claim 1, wherein the service interface implementation is a first service interface implementation, wherein the at least one service interface is a first service interface, the method further comprising:

providing a second service implementation corresponding to a second service interface, wherein the second service implementation is a static service interface implementation if the second service interface and the second service interface implementation are coded in a same computer language; and

executing the static service interface implementation to allow access to the client component to a service provided by the target component.

9. The method of claim 1, wherein the dynamic service implementation interface has a single invoke method with parameters that correspond to functions whose signatures are included in the corresponding service interface, and wherein the at least one service interface has a signature identifying parameters of the service interface, the method further comprising:

providing an implementation of the signature in the at least one service interface

10. The method of claim 1, wherein pre-existing methods that implement signatures included in the at least one service interface cannot be modified, the method further comprising:

mapping the signatures to the pre-existing methods.

11. A system, comprising;
