System and method for meta-data driven, semi-automated generation of web services based on existing applications
First Claim
1. A method for facilitating reuse of logic implemented in an existing software application, the method comprising:
- receiving, at a computer system configured to run a Web service, a payload file representing an invocation of a Web service operation that causes an existing operation implemented in an existing software application to be executed, the payload file including one or more input parameter values; and
invoking, at the computer system, an orchestration process configured to;
invoke a set of one or more utility Web services to facilitate execution of the Web service operation;
cause generation of a final payload file based at least in part on the payload file, the final payload file identifying the existing operation, a sequence of sub-operations to be performed by the existing software application in order to carry out the existing operation, and the one or more input parameter values; and
communicate with the existing software application and cause the existing software application to execute the existing operation based at least in part on the final payload file;
wherein at least one utility Web service of the set of one or more utility Web services is invoked based at least in part on a mapping between the existing operation and an alternative operation name.

Abstract
Techniques for reusing logic implemented in an existing software application such that the logic can be exposed as a Web service or in any other service-oriented context. In one set of embodiments, a design-time technique is provided that comprises, inter alia, receiving program code for an existing software application, generating metadata based on the program code, and customizing the metadata to align with an intended Web service. Artifacts for the Web service are then generated based on the customized metadata. In another set of embodiments, a run-time technique is provided that comprises, inter alia, receiving a payload representing an invocation of a Web service operation of the generated Web service, processing the payload, and, based on the processing, causing the existing software application to execute an operation in response to the invocation of the Web service operation.

9. A system to facilitate reuse of logic implemented in an existing software application, the system comprising:
a first computer system configured to run a Web service, the first computer system comprising one or more processors to execute instructions to; receive a payload file representing an invocation of a Web service operation that causes an existing operation implemented in an existing software application to be executed, the payload file including one or more input parameter values; and invoke an orchestration process configured to; invoke a set of one or more utility Web services to facilitate execution of the Web service operation; cause generation of a final payload file based at least in part on the payload file, the final payload file identifying the existing operation, a sequence of sub-operations to be performed by the existing software application in order to carry out the existing operation, and the one or more input parameter values; and communicate with the existing software application and cause the existing software application to execute the existing operation based at least in part on the final payload file; wherein at least one utility Web service of the set of one or more utility Web services is invoked based at least in part on a mapping between the existing operation and an alternative operation name. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. One or more non-transitory, machine-readable media having machine-readable instructions thereon to facilitate reuse of logic implemented in an existing software application, which instructions, when executed by one or more computers or other processing devices, cause the one or more computers or other processing devices to:
-
receive a payload file representing an invocation of a Web service operation that causes an existing operation implemented in an existing software application to be executed, the payload file including one or more input parameter values; and invoke an orchestration process configured to; invoke a set of one or more utility Web services to facilitate execution of the Web service operation; cause generation of a final payload file based at least in part on the payload file, the final payload file identifying the existing operation, a sequence of sub-operations to be performed by the existing software application in order to carry out the existing operation, and the one or more input parameter values; and communicate with the existing software application and cause the existing software application to execute the existing operation based at least in part on the final payload file; wherein at least one utility Web service of the set of one or more utility Web services is invoked based at least in part on a mapping between the existing operation and an alternative operation name. - View Dependent Claims (18, 19, 20)
