REST'ing @ SailFin CAFE

Converged (Http/SIP) applications gives users the flexibility of creating or accessing information about their communications (call/conferences/im ...) over the web. To make this possible a typical converged application would contain an entry point for all the Http requests, which is mostly an Http Servlet. This servlet would return back appropriate responses by accessing the corresponding communication (SIP) sessions. Every communication application that is deployed would need one (or more) Http servlets in order to support Web clients (as shown in figure 1). But, the fact is that most of the operations that are required by web clients are quite similar and do not differ much on the server side with respect to the implementation of the http servlet. Common tasks a web client might do include setting up a call (CallSetup), querying status of calls, terminating a call, modifying a call etc... From a developers perspective its desirable if the converged application development framework provides a means of exposing these common tasks rather than having to write a htttp servlet for it. It also helps if these are exposed as an API, that is portable as well as open standards compliant.    Figure 1   SailFin CAFE solves this problem by exposing these through a REST API. When a CAFE application is deployed (with some information added to web.xml descriptor), all the regular tasks of creating and managing the communica...
