Abstract

A method includes receiving a selection of a predefined implementation variation for a variable service component in at least one computing device configured to implement a service-oriented application; and executing source code associated with the variable service component in response to receiving the selection, wherein the source code performs a predetermined rebuilding of at least a portion of the service-oriented application such that the variable service component is redefined according to the selected implementation variation.

Claims

1. A method comprising:

receiving a selection of a predefined implementation variation for a variable service component in at least one computing device configured to implement a service-oriented application; and

executing source code associated with said variable service component in said at least one computing device in response to receiving said selection,

said source code performing a predetermined rebuilding of at least a portion of said service-oriented application such that said variable service component is redefined according to said selected implementation variation.

2. The method of claim 1, in which said variable service component comprises at least one of:

a service, a process implemented by a service, a service description, a service communication protocol, and a service communication transmission.

3. The method of claim 1, in which said variable service component is a component of a service contract for a service in said service-oriented application.

4. The method of claim 1, in which said variable service component comprises variability information that defines how and to what extent said variable service component may be varied.

5. The method of claim 1, in which said predefined implementation variation comprises at least one of:

adding at least one message field to an input/output message definition associated with said variable service component, removing at least one message field from said input/output message definition, and modifying at least one message field in said input/output message definition.

6. The method of claim 1, in which said predefined implementation variation comprises adding a service operation to a service, removing a service operation from a service, modifying a service operation associated with a service, adding a non-functional requirement of a service, removing a non-functional requirement of a service, and modifying a non-functional requirement of a service.

7. The method of claim 1, further comprising receiving at least one parameter associated with said selection from said predetermined set of available variations in said service component.

8. A method for rebuilding a service-oriented application, said method comprising:

defining variable portions of a service component in a service model associated with said service-oriented application;

providing source code configured to implement predefined variations in said service component;

receiving a selection of one of said predefined variations related to said service component in at least one computing device configured to implement a service oriented application; and

performing by said source code a predetermined rebuilding process on said service component in said service-oriented application implemented by said computing device, using said selection of said predefined variations as an input.

9. The method of claim 8, wherein said predetermined rebuilding process is based on a variation definition in said source code.

10. The method of claim 8, wherein said service component comprises at least one of:

a service, a process implemented by a service, a service description, a service communication protocol, and a service communication transmission.

11. The method of claim 8, wherein said predetermined rebuilding process comprises:

modifying a service model;

modifying a deployment script; and

modifying at least one of;

a service component implementation at a code level, a service implementation at a configuration level, an affected business process, a service invocation client stub in the service-oriented application, and a user interface component.

12. The method of claim 11, wherein said variation comprises at least one of a message field to be added, a message field to be removed, and a message field to be modified.

13. The method of claim 12, wherein said message field is a component of an existing input/output message definition associated with said variable service component

14. The method of claim 8, further comprising receiving at least one parameter associated with said selection from said predetermined set of available variations in said service component.

15. A computer program product for rebuilding a service-oriented application, said computer program product comprising:

a computer readable storage medium comprising computer usable program code embodied therewith, wherein the computer usable program code comprises;

computer usable program code configured to receive a selection of a predefined implementation variation for a variable service component in a service-oriented application; and

computer usable program code configured to performs a predetermined rebuilding of at least a portion of said service-oriented application in response to receiving said selection such that said variable service component is redefined according to said selected implementation variation.

16. The computer program product of claim 15, wherein said variable service component comprises at least one of:

a service, a process implemented by a service, a service description, a service communication protocol, and a service communication transmission.

17. The computer program product of claim 15, further comprising computer usable code comprising variability information that defines how and to what extent said variable service component may be modified.

18. The computer program product of claim 15, wherein said predefined implementation variation comprises:

adding a message field, removing a message field, modifying a message field, adding a service operation, removing a service operation, modifying a service operation, adding a non-functional requirement of a service, removing a non-functional requirement of a service, and modifying a non-functional requirement of a service.

19. The computer program product of claim 18, wherein said message field is a component of an existing input/output message definition associated with said variable service component.

20. The computer program product of claim 15, further comprising computer usable code configured to receive at least one parameter associated with said selection from said predetermined set of available variations in said service component.
