Title: System and method for automated code generation using language neutral software code.
Inventor: WAQAR SADIQ
IPC: G06F9/44
Filed: 2004-01-22
Abstract: A system and method for composing, configuring deploying, and managing services in a data processing system and data processing system network. This system provides a means for application infrastructure services to insert specific programming code in the generated code. When code generator starts, it also loads the plugs for the infrastructure services being used by the container. The code generator creates XML documents for all the code that it wants to generate. It then invokes the infrastructure service plugs and provides them an opportunity to add code specific to them by passing the XML documents representing the code to be generated. Once all the plugs have added their code, the code generator converts the XML documents back into either language specific code or configuration code, as necessary.
