Abstract

A method, computer program product and system for displaying Web services. Web services may be displayed by generating a data model of a description of the Web service. A perspective visitor may be applied to the generated data model where the perspective visitor corresponds to a preselected domain. A perspective of the Web service associated with the preselected domain may be displayed in response to applying the perspective visitor. The perspective visitor may include a visitor pattern for encapsulating an operation to be performed on elements of the data model.

Claims

1. A method for displaying Web services comprising:

generating a data model of a description of the Web service;

applying a perspective visitor to the data model, wherein the perspective visitor corresponds to a preselected domain; and

displaying a perspective of the Web service associated with the preselected domain in response to the step of applying the perspective visitor, wherein the perspective visitor comprises a visitor pattern for encapsulating an operation to be performed on elements of the data model.

2. The method of claim 1 further comprising iterating the steps of applying a perspective visitor to the data model and displaying the perspective of the Web service for each perspective corresponding to one of a predetermined set of domains.

3. The method of claim 2 wherein the set of domains includes Java, SOAP, Java server Pages, and Visual Basic.

4. The method of claim 1 wherein the data model comprises a data structure including at least one node corresponding to an operation of the Web service, and at least one child node of a node corresponding to an operation, the child node corresponding to one of an input and an output of the Web service.

5. The method of claim 4 wherein the step of applying the perspective visitor further includes:

passing in the at least one node and the at least one child node to the perspective visitor; and

populating the perspective corresponding to the preselected domain to generate a corresponding perspective representing the node passed in.

6. The method of claim 1 further comprising:

receiving user input sample data in response to the step of displaying the perspective; and

executing the Web service using the sample data.

7. A computer program product embodied in a machine-readable storage medium comprising programming instructions for performing the steps of:

generating a data model of a description of the Web service;

applying a perspective visitor to the data model, wherein the perspective visitor corresponds to a preselected domain; and

displaying a perspective of the Web service associated with the preselected domain in response to the step of applying the perspective visitor, wherein the perspective visitor comprises a visitor pattern for encapsulating an operation to be performed on elements of the data model.

8. The computer program product of claim 7 further comprising programming for performing the step of iterating the steps of applying a perspective visitor to the data model and displaying the perspective of the Web service for each perspective corresponding to one of a predetermined set of domains.

9. The computer program product of claim 8 wherein the set of domains includes Java, SOAP, Java Server Pages, and Visual Basic.

10. The computer program product of claim 7 wherein the data model comprises a data structure including at least one node corresponding to an operation of the Web service, and at least one child node of a node corresponding to an operation, the child node corresponding to one of an input and an output of the Web service.

11. The computer program product of claim 10 wherein programming for performing the step of applying the perspective visitor further includes programming for performing the steps of:

passing in the at least one node and the at least one child node to the perspective visitor; and

populating the perspective corresponding to the preselected domain to generate a corresponding perspective representing the node passed in.

12. The computer program product of claim 7 further comprising:

receiving user input sample data in response to the step of displaying the perspective; and

executing a Web page calling the Web service using perspective and the sample data.

13. A data processing system for displaying Web services comprising:

circuitry operable for generating a data model of a description of the Web service;

circuitry operable for applying a perspective visitor to the data model, wherein the perspective visitor corresponds to a preselected domain; and

circuitry operable for displaying a perspective of the Web service associated with the preselected domain in response to the step of applying the perspective visitor, wherein the perspective visitor comprises a visitor pattern for encapsulating an operation to be performed on elements of the data model.

14. The system of claim 13 further comprising circuitry operable for iterating the operations of applying a perspective visitor to the data model and displaying the perspective of the Web service for each perspective corresponding to one of a predetermined set of domains.

15. The system of claim 14 wherein the set of domains includes Java, SOAP, Java Server Pages, and Visual Basic.

16. The system of claim 13 wherein the data model comprises a data structure including at least one node corresponding to an operation of the Web service, and at least one child node of a node corresponding to an operation, the child node corresponding to one of an input and an output of the Web service.

17. The system of claim 16 wherein the circuitry operable for applying the perspective visitor further includes:

circuitry operable for passing in the at least one node and the at least one child node to the perspective visitor; and

circuitry operable for populating the perspective corresponding to the preselected domain to generate a corresponding perspective representing the node passed in.

18. The system of claim 13 further comprising:

circuitry operable for receiving user input sample data in response to the step of displaying the perspective; and

circuitry operable for executing a Web page calling the Web service using the perspective and the sample data.

19. A method for displaying Web services comprising:

generating a data model of a description of the Web service;

applying a perspective visitor to the data model, wherein the perspective visitor corresponds to a preselected domain; and

displaying a perspective of the Web service associated with the preselected domain in response to the step of applying the perspective visitor, wherein the perspective visitor comprises a visitor pattern for encapsulating an operation to be performed on elements of the data model, wherein the data model comprises a data structure including at least one node corresponding to an operation of the Web service, and at least one child node of a node corresponding to an operation, the child node corresponding to one of an input and an output of the Web service.
