Abstract

A service-oriented computer programming language is disclosed. The language includes keywords and operators that enable simple definition and invocation of SOAP services. In operation, a linkable data entity can be associated with one or more SOAP services dynamically, such that the SOAP services associated with the linkable data entity at any given time can change as a computer program executes. In addition, once a SOAP service is associated with a linkable data entity, the association can persist until it is eliminated, changed, or the computer program completes execution.

Claims

1. A method of processing an executable computer program with a language processor, the method comprising:

parsing a keyword in the executable computer program, the keyword defining a SOAP service invocation;

generating a first output recognizing the presence of the SOAP service invocation in the executable computer program;

adding semantic information to the first output; and

generating a second output based on the contents of the first output and including one or more structures containing the SOAP service invocation, including a reference to an operation associated with the SOAP service.

2. The method of claim 1, further comprising:

generating a SOAP request compliant with the requirements of the referenced operation of the SOAP service; and

dispatching the SOAP request to invoke the referenced operation in the SOAP service.

3. The method claim 1, wherein the first output further recognizes an input comprising an expression evaluating to a SOAP message in its entirety or a set of expressions, each one evaluating to a value that can be packaged in a SOAP request

4. The method of claim 1, wherein the keyword is “

invoke.”

5. The method of claim 1, wherein the first output comprises a parse tree.

6. The method of claim 1, wherein the second output comprises a symbol table.

7. The method of claim 1, wherein the language processor comprises an interpreter.

8. The method of claim 1, wherein the language processor comprises a compiler.

9. A method of processing an executable computer program with a language processor, the method comprising:

parsing a keyword in the executable computer program, the keyword defining a SOAP service,

generating a first output recognizing the presence of the SOAP service in the executable computer program, as well as one or more operations and message input and output types associated with the SOAP service;

adding semantic information to the first output; and

generating a second output based on the contents of the first output and including one or more structures containing the SOAP service, including one or more associated operations, message input and output type references, and statements defining behaviors of each operation.

10. The method of claim 9, further comprising, upon invocation of the SOAP service, exhibiting behaviors defined within the SOAP service.

11. The method of claim 9, wherein the keyword is “

service.”

12. The method of claim 9, wherein the first output comprises a parse tree.

13. The method of claim 9, wherein the second output comprises a symbol table.

14. The method of claim 9, wherein the language processor comprises an interpreter.

15. The method of claim 9, wherein the language processor comprises a compiler.

16. A method for linking one or more SOAP services to a linkable data entity in an executable computer program, the method comprising:

identifying the linkable data entity;

associating the linkable data entity with one or more SOAP services,

wherein the SOAP services associated with the linkable data entity at any given time can change as the computer program executes, and

wherein, once a SOAP service is associated with the linkable data entity, the association persists until it is eliminated, changed, or the computer program completes execution.

17. The method of claim 16, wherein the linkable data entity is implemented in a service-oriented programming language.

18. The method of claim 16, wherein the SOAP service is implemented in a service-oriented programming language.

19. The method of claim 16, wherein associating the linkable data entity with one or more SOAP services comprises utilizing a keyword in a service-oriented programming language.

20. The method of claim 16, wherein associating the linkable data entity with one or more SOAP services comprises utilizing an operator in a service-oriented programming language.
