Abstract

A method of generating code that permits client access to a business process orchestration running on a server as a web service using the Simple Object Access Protocol (SOAP). Business process orchestrations in XLANG are converted to a web service implementation description from which the Web services code is generated. During runtime, when a SOAP request message comes into the server, it is passed to the target web method. The message is then passed to a Web services adapter that submits the request for further processing by the backend system. The response is forwarded to the Web services adapter, which returns the response as a SOAP response message to the client.

Claims

1. A computer-implemented method for generating an XML Web service to expose a business process orchestration, the method comprising:

generating a web service implementation and web services description language (WSDL) from an assembly representative of said business process orchestration, wherein generating the web service implementation comprises using reflection to extract information regarding the business process orchestration and ports contained in the assembly;

mapping XLANG messages and messagetype parts to web method parameters and return values in the web service implementation such that an input pararmeter name in the implementation is obtained by taking a messagetype part name for each part of a request message and an output parameter name is obtained by taking the messagetype part name for each part of the request message;

generating orchestration proxy code from the web service implementation;

generating the web service implementation and WSDL from a selection of schemas provided by a BizTalk Adapter; and

wrapping said orchestration proxy code within a web method.

2. The method of claim 1, wherein the assembly is a BizTalk assembly and generating the web service implementation using reflection comprises using .NET Reflection to extract information regarding orchestrations and ports contained in the BizTalk assembly.

3. The method of claim 1, further comprising:

generating or referencing CLR types (.NET classes) to represent XLANG message types.

4. The method of claim 1, wherein the output parameter name is obtained by taking the messagetype part name for each part of the request message and appending an underscore.

5. The method of claim 1, further comprising mapping XLANG ports and porttypes to a web service class in the implementation witch corresponds to a porttype element in a WSDL file.

6. The method of claim 5, wherein said web service class name is generated by concatenating an XLANG module name, service name, and port name separated by underscores and with all dots converted to underscores so as to produce a valid unique C# identifier name.

7. The method of claim 1, further comprising:

creating an ASP.NET web service project from the web service implementation;

generating data types (.NET classes) used as the web method parameters; and

generating each web method specific.

8. A system adapted to generate an XML Web service to expose a business process orchestration, the system comprising:

at least one processor;

memory communicatively coupled with said at least one processor, the memory having stored therein instructions executable on said at least one processor, the instructions for performing the following;

generating a web service implementation and web services description language (WSDL) from an assembly representative of said business process orchestration, wherein generating the web service implementation comprises using reflection to extract information regarding the business process orchestration and ports contained in the assembly;

mapping XLANG messages and messagetype parts to web method parameters and return values in the web service implementation such that an input parameter name in the implementation is obtained by taking the messagetype part name for each part of a request message and an output parameter name is obtained by taking the messagetype part name for each part of the request message;

generating orchestration proxy code from the web service implementation;

generating the web service implementation and WSDL from a selection of schemas provided by a BizTalk Adapter; and

wrapping said orchestration proxy code within a web method.

9. The system of claim 8, wherein the instructions for generating the web service implementation using reflection comprise using NET Reflection to extract information regarding orchestrations and ports contained in a BizTalk assembly.

10. The system of claim 8, further comprising instructions for generating or referencing CLR types (.NBT classes) to represent XLANG message types.

11. The system of claim 8, wherein the output parameter name is obtained by taking the messagetype part name for each part of the request message and appending an underscore.

12. The system of claim 8, further comprising instructions for mapping XLANG ports and porttypes to a web service class in the implementation which corresponds to a porttype element in a WSDL file.

13. The system of claim 12, wherein a web service class name is generated by concatenating the an XLANG module name, service name, and port name separated by underscores and with all dots converted to underscores so as to produce a valid unique C# identifier name.

14. The system of claim 8, further comprising instructions for performing:

creating an ASP.NET web service project from the web service implementation;

generating data types (.NET classes) used as the web method parameters; and

generating each web method specific.

15. A computer-readable storage medium having stored thereon information comprising;

computer-readable instructions for generating a web service implementation and web services description language (WSDL) from an assembly representative of said business process orchestration, wherein generating the web service implementation comprises using reflection to extract information regarding the business process orchestration and ports contained in the assembly;

computer-readable instructions for mapping XLANQ messages and messagetype parts to web method parameters and return values in the web service implementation such that art input parameter name in the implementation is obtained by taking the messagetype part name for each pan of a request message and an output parameter name is obtained by taking the messagetype part name for each pan of the request message;

computer-readable instructions for generating orchestration proxy code from the web service implementation;

computer-readable instructions for generating the web service implementation and WSDL from a selection of schemas provided by a BizTalk Adapter; and

computer-readable instructions for wrapping said orchestration proxy code within a web method.

16. The computer-readable storage medium of claim 15, wherein the computer-readable instruction for generating the web service implementation using reflection comprise using .NET Reflection to extract information regarding orchestrations and ports contained in a BizTalk assembly.

17. The computer-readable storage medium of claim 15, further comprising computer-readable instructions for generating or referencing CLR types (.NET classes) to represent XLANG message types.

18. The computer-readable storage medium of claim 15, wherein computer-readable instructions for obtaining the output parameter name comprise taking the messagetype part name for each part of the request message and appending an underscore.

19. The computer-readable storage medium of claim 15, further comprising computer-readable instructions for mapping XLANG ports arid porttypes to a web service class in the implementation which corresponds to a porttype element in a WSDL file.

20. The computer-readable storage medium of claim 19, wherein computer-readable instructions for generating the web service class name comprise concatenating an XLANG module name, service name, and port name separated by underscores and with all dots converted to underscores so as to produce a valid unique C# identifier name.

21. The computer-readable storage medium of claim 15, further comprising computer-readable instructions for:

creating an ASP.NET web service project from the web service implementation;

generating data types (.NET classes) used as the web method parameters; and

generating each web method specific.
