ECharts, Grails and SailFin

EChart logo

ECharts is a state machine-based programming language which supports Java as a host language. E4SS (ECharts for Sip Servlets) has introduced native support for SailFin some time back. This special build consists of a JSR 289 based application router, which can be directly deployed to SailFin SIP container.

Recently, Gregory Bond from AT&T, has come up with a tutorial style article describing in detail how to use E4SS, Grails and SailFin to implement, build and run a simple converged telecom application. Also checkout some screen shots at the end of the document.

AT&T's ECharts releases beta for Sailfin

EChart logo

ECharts is open source software to program SIP Servlets with feature boxes, SIP message ports, and state-machine logic rather than overriding servlet methods and managing sessions.

SailFin Milestone 2 is supported in the latest ECharts for SIP Servlets DK (version 2.2 beta), providing thus a full open source solution. More details on the combination here.

ECharts for SIP Servlets DK also includes a JSR289-compliant application router implementation that enables SIP Servlet 1.1 application composition.

Check this ECharts for SIP Servlets Screencast for a feel of what it's like to program a back-to-back user agent application using the ECharts language (syntax similar to Java, only with "states" and "transations").
