Application server framework

Abstract

An application server framework is integrated with a three-tiered computer system including an application server. The application server framework includes a job scheduler, a connection controller, a listener, and a service broker. The jobs scheduler is integrated with the application server and independently requesting execution of services. The connection controller establishes connections with services based upon the requested execution of services. The listener receives requests for execution of services and transmitting the requested execution of services to the connection controller. The service broker transmits the requests for execution of services to the listener.
