摘要:
A framework having a plurality of directories representing different types of middlewares and distributed object systems can be constructed from data provided in a class library. Each directory includes the name and address of all service objects, located across multiple servers in the system, that supports the specific middleware or distributed object policy characteristics for that directory. One service object may be addressed through multiple directories. When a remote method call is issued by a client, a list of service objects capable of executing the call is obtained from the directories and one object selected. The policy characteristics associated with the directory from which the object address is selected, are attached to the call. These characteristics are validated when the addressed server receives the call. In this way, a client program can be written entirely independently of the middleware or peculiarity of implementation of the distributed object service.

The present invention is directed to a system for for automated interface generation for computer programs operating in different environments. The system comprises a utility which imports a CICS COBOL transaction source file, parses the communication area of the CICS file, and generates modelling information. The modelling information represents the nature and structure of data in the CICS transaction source file, and is written to a persistent data store. The utility uses the information in the persistent data store to generate an application programming interface. The application programming interface takes the data values from the other language and translates them to a formatted CICS COBOL communications area. This format is derived from the definition of the CICS communications area contained in the imported CICS program. After the translation runs, the resulting CICS COBOL communications area is translated back to the data values of the other language. This translation step also handles the data conversion between different codepages and machine architectures and program semantics. The resulting language values represent the result of the transaction. The CICS transaction is accessed using the CICS External Call Interface mechanism.

A Web services access management system which enables loosely coupled Web services can include a servlet configured to receive incoming request messages to access business logic and a mapping table associating different ones of the request messages with different business logic. Mapping logic can be disposed between the servlet and the business logic and configured to route at least part of the incoming request messages to selected ones of the business logic according to the mapping table. Finally, the system can include a response builder configured to build responses with data produced by the business logic responsive to processing incoming request messages routed by the mapping logic. In this regard, changes to the mapping logic can remain transparent to clients transmitting request messages and the business logic servicing the requests.
