SailFin

---

Project SailFin is based on robust and scalable SIP servlets technology on top of a deployment-quality, Java EE-based GlassFish. We are working towards achieving JSR 289 compatibility, adding high- availability and clustering features, and integrating with existing GlassFish services. 

JSR 289 updates the SIP Servlets API and defines a standard application programming model to mix SIP Servlets and Java EE components. Java EE services, such as web services, persistence, security, and transactions, enable faster development of smarter communications-enabled applications.
