A SIP application is a set of SIP servlets packaged in
a SIP application archive file (SAR).
About this task
A SIP servlet is an application component managed by the
SIP container that performs SIP signaling. The programming and deployment
models are analogous to web servlets and therefore will be mapped
to the WebSphere administrative model accordingly. It is possible
to include web servlets in a SAR file (along with the required web.xml
deployment descriptor) to create what is known as a converged application.
See JSR 116 for details on SIP applications, servlets, converged applications,
and status codes.
