Abstract: Federated applications are configured to use both modules created for the applications as well as library modules which perform commonly used functions. The library modules are stored separately for deployment when utilized by applications. A deployment descriptor is configured with descriptions of internal modules and references to library modules. A deployment tool reads the deployment descriptor, extracts the library modules according to the information stored in the deployment descriptor, and loads the modules specific to the application.

Abstract: The invention provides a system and method for providing http request preprocessing for servlets. Preprocessors are server-side components designed to handle HTTP requests, and are primarily targeted for use with Web applications written according to the J2EE Servlets and JSP specifications. To do this, the invention provides an architecture for the support of preprocessing HTTP requests. During request processing, the preprocessor components gain control before J2EE servlets are invoked. The preprocessors can thus influence the behavior of the servlet engine by participating in targeting the request to a servlet.
