APPARATUS AND SYSTEM FOR PRODUCING ATOM FEEDS WITH J2CA ADAPTERS

摘要

A servlet for enabling communications between a client having an Atom feed reader and an Enterprise Information System (EIS). The servlet enables communications between the client and the EIS by acting as a proxy for an J2CA resource adapter deployed on an application server. The servlet receives HTTP requests from the Atom feed reader and translates those requests into appropriate adapter function calls based on the specified HTTP function and the provided key information. The servlet then invokes the appropriate functions and receives the response from the adapter. If a single object is returned by the adapter, the servlet translates the object into Atom-compliant XML and transmits it to the Atom feed reader as the response. If multiple objects are returned, the servlet generates a list of URLs which uniquely specify and identify each object returned by the adapter and provides this list to the Atom feed reader.
