Mark Wielaard: New GPG key.
Finally created a new GPG key using gnupg. The old one was a DSA/1024 bits one and 8 years old. The new one is a RSA/2048 bits one. I will use the new one in the future to sign any release tarballs I might create. pub 2048R/57816A6A 2011-01-29 Key f...

SailFin CAFE Fundamentals: CommunicationBeans and Agents.
SIP Servlets provide a server side Java abstraction to SIP protocol and it is based on familiar servlet model. This enables an application developer to use Java servlet programming to write Converged applications. What exactly is the meaning of "converged applications"? SIP Servlet Specification explains this as follows
"While the SIP Servlet API can certainly be implemented independently of the HTTP Servlet API, it is expected that many interesting services will combine multiple modes of communication, for example, telephony, Web, email, instant messaging and other server side components like Web services and other Java EE interfaces." SIP Servlet specification defines SIP Application Session, which is a session that holds child protocol sessions (Http Session and Sip Sessions). The lifecycle of this Application Session is defined by the application itself. Thus it provides a flexible mechanism to share data between HTTP and SIP Sessions on an application defined scope. SIP Servlets also enable Java EE components to compose and send SIP requests as per RFC 3261.
SIP Servlets is one step in the right direction. I.e it provides a way to write applications that mixes SIP with other Java EE technologies. However, this forces application developer to learn SIP protocol. That would take the developer to the SIP RFC hell. Take a look at this RFC to list SIP RFCs and imagine an average web developer starting to write SIP applicati...
