E4SS, Grails and SailFin Print
Written by Gregory W. Bond   
Over the past year, I've been familiarizing myself with the latest web application development frameworks like Ruby on Rails, Grails, Pylons etc. My interest has been motivated by the prospect of rapidly developing converged (SIP + HTTP) telecom applications using ECharts for SIP Servlets (E4SS) and one of these frameworks.

SIP Application Competitions Print
Written by Gregory W. Bond   
In addition to the GlassFish Awards Program, which includes SailFin-oriented projects, a new competition was announced at JavaOne this week. The Sun-Ericsson application competition will be awarding prizes for the best IMS client-server application using the open source SailFin SIP servlet container and Ericsson's Service Development Studio. Both competitions are great opportunities to give ECharts for SIP Servlets a try. You'll quickly see that ECharts for SIP Servlets is the best way to develop non-trivial, robust, converged SIP applications.

The Year of the Open Source SIP Servlet Container Print
Written by Gregory W. Bond   
Starting with the SailFin announcement at last year's JavaOne conference, followed by the release of the Mobicents Sip Servlets implementation mid-January and then, this month, the release of the Cipango application server, I think it's safe to proclaim that this is the year of the open source SIP servlet container.

Call Screening Application for SailFin Print
Written by Gregory W. Bond   
Peter Klein is a community tester for the open source SailFin SIP servlet container project. Over the past month Peter has posted 4 entries to his blog detailing the development of a converged Call Screening application using ECharts for SIP Servlets, the AT&T DFC Application Router (included with the ECharts for SIP Servlets Development Kit) and SailFin.

Multi-Browser Support for SVG Diagrams Print
Written by Gregory W. Bond   
A recent blog post of mine discussed the current state of viewing ECharts javadocmachine SVG diagrams with different browsers. Given how close Safari 3 and Firefox 2 have gotten to achieving parity with the Adobe SVG plugin I decided to turn my attention to investigating what was necessary to achieve complete parity.

We are happy to announce that the new release of ECharts for SIP Servlets DK, version 2.2 beta, now supports the open-source SailFin SIP servlet container.  This blog entry describes some SailFin specific procedures and gotchas when deploying ECharts for SIP Servlets applications on the SailFin container.

Viewing SVG Machine Diagrams Print
Written by Gregory W. Bond   
I just upgraded to the latest Safari version 3.0.4 (bundled with Mac OS X 10.4.11 and 10.5 and available as a separate download for Windows) and decided to check out its SVG support by viewing the machine diagrams in the ECharts for SIP Servlets DK online Javadocs. To my delight, pressing the machine button for the B2buaFSM displays the machine's diagram. Hovering over machine transitions and states highlights them as expected. Furthermore, clicking on states with embedded machines displays the embedded machine's diagram. Wow! The same capabilities are present in Firefox version 2.x which runs on the Mac, Linux and Windows. This is really encouraging given that Adobe's SVG plugin is officially end-of-lifed and won't be supported after January 2009.

Proxy Application Support Print
Written by Tom Smith   
The state-based approach of ECharts makes it very well-suited to back-to-back user agent (B2BUA) applications.  With the introduction of the SIP Servlet Application Router, multiple applications can be composed to get rich service behavior.  Often it is beneficial to compose proxy applications with B2BUA applications.  Our framework provides a mechanism for creating proxy applications (that are not based on state machines) and composing them with ECharts B2BUA applications.
