Local transparent extensibility and routing slip extensibility for business process execution language

A method for orchestrating web services comprising:

• performing by a computer system programmed with code stored in a memory and executing by a processor of the computer system that configures the computer system into a machine for:
• receiving an input message by a processor executable service of the code that orchestrates web service requests and utilizes an extension element whose address is identified in the input message, wherein the extension element implements computer executable logic that receives the input message that corresponds to a web service description language definition of the extension element;
• determining based on a plurality of a physical addresses included in the received input message, a location of a copy of the extension element of the plurality of copies;
• and
• responsive to determining the location of the copy of the extension element, directing a normalized message to the determined location of the extension element for processing by the logic of the extension element.

A system for providing location extensibility for a business process execution language, the system comprising:

• a processor;
• a non-transitory computer readable medium, coupled to the processor, storing code executable by the processor that configures the system into a machine that comprises:
• a business process execution language service for processing messages, orchestrating web service requests, and utilizing an extension element whose address is identified in at least one of the messages, wherein the extension element implements computer executable logic that receives the input message that corresponds to a web service description language definition of the extension element;
• a resolver for providing a mapping from the address for the extension element to a location of the extension element;
• and
• a container for using the resolver to process the at least one of the messages for directing the processed message to the location of the extension element for processing by the extension element, wherein the container coupled to interact with the resolver and the business process execution language service.

A non-transitory computer readable storage medium configured to store instructions, the instructions when executed by a processor that configures a computer system that includes the processor into a machine to:

• receive an input message by a processor executable service of the code, and the processor executable service orchestrates web service requests and utilizes an extension element whose address is identified in the input message, wherein the extension element implements computer executable logic that receives the input message that corresponds to a web service description language definition of the extension element;
• determine, based on the address identifying the extension element included in the received input message, a location of the extension element;
• and
• responsive to determining the location of the extension element, direct a normalized message to the location of the extension element for processing by the logic of the extension element.
