Patent ID: 7509638

Claim:
A method, in a data processing system, for deploying an enterprise application into a runtime environment, comprising: identifying at least one extension point in a module of the enterprise application; identifying at least one plug-in module in a plurality of plug-in modules defining extensions of the at least one extension point, wherein the at least one plug-in module in the plurality of plug-in modules is an extension of another one of the plurality of plug-in modules, wherein the at least one plug-in module provides extended functionality to the enterprise application thereby permitting the enterprise application to perform functions that it could not perform prior to integration of the at least one plug-in module, wherein the at least one plug-in module is identified in the configuration information based on a Uniform Resource Identifier associated with the at least one plug-in module, wherein a schema is associated with each extension point, and wherein a plug-in module conforms to the schema of an extension point in order to extend the functionality of the enterprise application using the extension point; and integrating the at least one plug-in module into the enterprise application based on configuration information associated with the at least one plug-in module and the at least one extension point, wherein integrating the at least one plug-in module into the enterprise application further comprises: processing at least one manifest file associated with the at least one plug-in module to generate configuration information for the at least one plug-in module, wherein the manifest file is an extensible markup language file that identifies the functionality of the plug-in module and identifies the extension point through which the plug-in module may be extended; merging the configuration information for the at least one plug-in module into at least one configuration file of the enterprise application; and packaging the at least one plug-in module into a web archive file associated with the enterprise application.
