Sun Plans Open-Source Communications Server

Java is already very successful on mobile devices and servers (, so focusing
on mobile application servers makes sense. Much of the buzz at this week's
JavaOne Conference has been around Glassfish (which isn't surprising, as
Glassfish is Sun's open-source project around Java Enterprise Edition) and
the participation of Ericsson is important.

Ericsson's involvement is significant, as it could eventually mean an
carrier-class, open-source implementation of IMS. Though developed for (and
still used mostly by) 3G operators, IMS has applications for enterprises
wanting to take control of fixed-mobile convergence, and an open-source
version will add to its appeal.

Perhaps lost among the waves of news from this week's JavaOne show is this tidbit: Sun has begun working with Ericsson and the GlassFish community to develop an open-source, Java-based communications server.

Ericsson is contributing its SIP (Session Initiation Protocol)-based application server to the project under open-source licenses. That code will serve as the basis for a JSR 289-compatible SIP servlet container that can run on Java application servers. Sun plans to bring a Sun-supported product--dubbed the Sun Java System Communications Application Server--to market based on the open-source code.

The server will let IT access telephony capabilities in support of multimedia, voice over IP, instant messaging and next-generation CTI applications, the vendors said.
