Application compositor for converged SIP and HTTP servlet applications background

摘要

An application compositor enables the creation a sequence of SIP and HTTP servlets that comprises a converged multi-protocol application. Applications are constructed based on rules that declaratively specify a multi-protocol sequence of servlets and the transitions between the servlets, minimizing programmer effort. The application compositor works with a servlet container within an application server to determine the sequence of servlets to be executed by the servlet container when running the application, and is called by the servlet container to perform transitions between servlets.

1. A method for executing a server application comprising:
receiving a request to execute a server application from a requester, wherein the server application includes two or more servlets, wherein each servlet is either a SIP servlet or an HTTP servlet; in response to receiving the request, accessing rules associated with sequencing the server application; executing the first servlet; determining a first transition from the first servlet to a second servlet; executing the second servlet; determining if the second servlet is a last servlet in the application sequence; if the second servlet is not the last servlet:
determining a second transition from the second servlet to a third servlet;executing the third servlet; and if the second servlet is the last servlet, completing execution of the server application.
