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:

in a computing device that is to implement a service-oriented application, receiving, from a customer, variation point information that defines how and to what extent a selected variable service component of the service-oriented application is to be varied;

executing source code associated with the variable service component in the computing device in response to receiving the variation point information,

receiving, from execution of the source code, a parameter associated with the variable service component from among a predetermined set of available variations of the variable service component;

with the source code, rebuilding a portion of the service-oriented application such that the variable service component is redefined according to the variation point information; and

when a non-functional variable service component is selected by the customer to be a variable service component, modifying a service model representing the service-oriented application and a deployment script of the service-oriented application.

2. The method of claim 1, wherein the 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, wherein the variable service component is a component of a service contract for a service in the service-oriented application.

4. The method of claim 1, wherein the variation point information defining how and to what extent the variable service component it to be varied comprises at least one of:

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

5. The method of claim 1, wherein the variation point information defining how and to what extent a variable service component is to be varied comprises instructions for at least one of:

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.

6. A method comprising:

in a computing device that is to implement a service-oriented application, receiving, from a customer, a selection of a predefined implementation variation for a variable service component of the service-oriented application, the selection comprising a parameter indicating a specific implementation variation from among a predetermined set of available implementation variations of the variable service component; and

in response to receiving the selection, executing source code associated with the variable service component in the at least one computing device to perform a predetermined rebuilding of the service-oriented application such that the variable service component is redefined according to the selected implementation variation;

wherein, when a non-functional variable service component is selected by the customer to be a variable service component, modifying a service model representing the service-oriented application and a deployment script of the service-oriented application.

7. The method of claim 6, wherein the 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.

8. The method of claim 6, wherein the variable service component is a component of a service contract for a service in the service-oriented application.

9. The method of claim 6, wherein the specific implementation variation selected specifies both how and to what extent the corresponding variable service component is varied.

10. The method of claim 6, wherein the specific implementation variation selected comprises at least one of:

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

11. The method of claim 6, wherein the specific implementation variation selected comprises at least one of:

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.

12. A computer program product for rebuilding a service-oriented application, the computer program product comprising:

a non-transitory computer readable storage medium comprising computer usable program code, the code, when executing, causing a computing device to;

receive from a customer, a selection of a predefined implementation variation for a variable service component of a service-oriented application, the selection comprising a parameter indicating a specific implementation variation from among a predetermined set of available implementation variations of the variable service component; and

in response to receiving the selection, execute source code associated with the variable service component in the at least one computing device to perform a predetermined rebuilding of the service-oriented application such that the variable service component is redefined according to the selected implementation variation;

when, a non-functional variable service component is selected by the customer to be a variable service component, modifying a service model representing the service-oriented application and a deployment script of the service-oriented application.

13. The product of claim 12, wherein the 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.

14. The product of claim 12, wherein the variable service component is a component of a service contract for a service in the service-oriented application.

15. The product of claim 12, wherein the specific implementation variation selected specifies both how and to what extent the corresponding variable service component is varied.

16. The product of claim 12, wherein the specific implementation variation selected comprises at least one of:

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

17. The product of claim 12, wherein the specific implementation variation selected comprises at least one of:

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.

18. The product of claim 12, wherein the rebuilding of the service-oriented application comprises modifying both a user interface and a deployment script associated with the variable service component.
