Distributed application proxy generator

A method of automatically generating a distributed application proxy, the method comprising:

• providing a proxy base class that includes remote invocation functionality for supporting distributed application computing, a system exception base class that includes error handling for implicit exceptions, and a proxy exception base class that includes error handling for explicit exceptions;
• deriving an application proxy class from the proxy base class based on parsing the distributed application contract;
• deriving a system exception proxy class from the system exception base class for automatic handling of implicit exceptions;
• and
• deriving, for each explicit exception identified in the distributed application contract during parsing, a proxy exception base class from the proxy exception base class, wherein each derived proxy exception class is populated with explicit exception information from the corresponding explicit exception defined in the distributed application contract.

A system for generating proxies for distributed software applications, the system comprising:

• a distributed application contract (DAC) defining a desired distributed software application;
• one or more base interface proxy classes that include distributed application functionality supporting remote invocation;
• one or more base exception proxy classes that include error handling functionality supporting trapping and processing of exceptions;
• and
• a proxy generator to generate a proxy that includes automated error handling by:
• deriving one or more interface proxy classes corresponding to software interfaces defined by the DAC from the base interface proxy classes;
• deriving one or more exception proxy classes corresponding to explicit exceptions defined in the DAC from the base exception proxy classes;
• configuring the exception proxy classes to include exception methods and error information corresponding to like information defined by the explicit exceptions in the DAC;
• and
• configuring the interface proxy classes to raise the exception methods defined by the exception proxy classes upon encountering one or more of the explicit exceptions defined in the DAC.
