Abstract

A method is described that involves comprising, during runtime in an object-oriented environment, invoking, from an object, a first Web services endpoint method to process a first message by: invoking the first Web services endpoint method through a first interface according to an endpoint method invocation format, where, the first Web services endpoint method is implemented with a first component that is provided one or more services by a first container. The method also involves invoking, from the object, a second Web services endpoint method to process a second message by: invoking the second Web services endpoint method through a second interface according to the endpoint method invocation format. The second Web services endpoint method is implemented with a second component that is provided one or more services by a second container. The first and second containers have respective interfaces that are different.

Claims

1. A method, comprising:

during runtime in an object-oriented environment in which one or more processors read program code from memory and process said program;

invoking, from an object, a first Web services endpoint method to process a first message by;

invoking said first Web services endpoint method through a first interface according to an endpoint method invocation format, said first Web services endpoint method implemented with a first component that is provided one or more services by a first container having a first container defined interface; and

,

invoking, from said object, a second Web services endpoint method to process a second message by;

invoking said second Web services endpoint method through a second interface according to said endpoint method invocation format, said second Web services endpoint method implemented with a second component that is provided one or more services by a second container having a second container defined interface, said first and second container defined interfaces being different, and said first and second interfaces having same front-ends with a back-end of said first interface same as said first container defined interface and a back-end of said second interface same as said second container defined interface, the first interface converting the first Web service endpoint method invocation formatted according to the front-end into a method invocation that is formatted for the first container at the first back-end and the second interface converting the second Web service endpoint method invocation formatted according to the front-end into a method invocation that is formatted for the second container at the second back-end.

2. The method of claim 1 wherein said first component is a servlet.

3. The method of claim 2 wherein said second component is a Java™

EJB.

4. The method of claim 1 wherein said method further comprises said object obtaining said first interface prior to said invoking of said first Web services endpoint.

5. The method of claim 4 wherein said method further comprises said object obtaining said second interface prior to said invoking of said second Web services endpoint.

6. The method of claim 5 wherein both said obtaining of said first interface and said obtaining of said second interface are made by invoking a same manager.

7. The method of claim 6 wherein said method further comprises said object retrieving an identifier of said first container from a collection of data that describes a web service designed to perform said first Web Service endpoint method, and, presenting said identifier to said manager in order to receive said first interface.

8. A computing system comprising a machine, said computing system also comprising instructions disposed on a computer readable storage medium, said instructions capable of being executed by said machine to perform a method, said method comprising:

during runtime in an object-oriented environment;

invoking, from an object, a first Web services endpoint method to process a first message by;

invoking said first Web services endpoint method through a first interface according to an endpoint method invocation format, said first Web services endpoint method implemented with a first component that is provided one or more services by a first container having a first container define interface; and

,

invoking, from said object, a second Web services endpoint method to process a second message by;

invoking said second Web services endpoint method through a second interface according to said endpoint method invocation format, said second Web services endpoint method implemented with a second component that is provided one or more services by a second container having a second container defined interface, said first and second container defined interfaces being different, and said first and second interfaces having same front-ends with a back-end of said first interface same as said first container defined interface and a back-end of said second interface same as said second container defined interface, the first interface converting the first Web service endpoint method invocation formatted according to the front-end into a method invocation that is formatted for the first container at the first back-end and the second interface converting the second Web service endpoint method invocation formatted according to the front-end into a method invocation that is formatted for the second container at the second back-end.

9. The computing system of claim 8 wherein said first component is a servlet.

10. The computing system of claim 9 wherein said second component is a Java™

EJB.

11. The computing system of claim 8 wherein said method further comprises said object obtaining said first interface prior to said invoking of said first Web services endpoint.

12. The computing system of claim 11 wherein said method further comprises said object obtaining said second interface prior to said invoking of said second Web services endpoint.

13. The computing system of claim 12 wherein both said obtaining of said first interface and said obtaining of said second interface are made by invoking a same manager.

14. The computing system of claim 13 wherein said method further comprises said object retrieving an identifier of said first container from a collection of data that describes a web service designed to perform said first Web Service endpoint method, and, presenting said identifier to said manager in order to receive said first interface.

15. An article of manufacture including program code stored on a machine readable storage medium which, when executed by a machine, causes the machine to perform a method, the method comprising:

during runtime in an object-oriented environment;

invoking, from an object, a first Web services endpoint method to process a first message by;

invoking said first Web services endpoint method through a first interface according to an endpoint method invocation format, said first Web services endpoint method implemented with a first component that is provided one or more services by a first container having a first container defined interface; and

,

invoking, from said object, a second Web services endpoint method to process a second message by;

invoking said second Web services endpoint method through a second interface according to said endpoint method invocation format, said second Web services endpoint method implemented with a second component that is provided one or more services by a second container having a second container defined interface, said first and second container defined interfaces being different, and said first and second interfaces having same front-ends with a back-end of said first interface same as said first container defined interface and a back-end of said second interface same as said second container defined interface, the first interface converting the first Web service endpoint method invocation formatted according to the front-end into a method invocation that is formatted for the first container at the first back-end and the second interface converting the second Web service endpoint method invocation formatted according to the front-end into a method invocation that is formatted for the second container at the second back-end.

16. The article of manufacture of claim 15 wherein said first component is a servlet.

17. The article of manufacture of claim 16 wherein said second component is a Java™

EJB.

18. The article of manufacture of claim 15 wherein said method further comprises said object obtaining said first interface prior to said invoking of said first Web services endpoint.
