NetBeans 6.1 Milestone 1 is feature-frozen. Vince reports on the improved integration with the sailfin project with : - Explicit reference to Sailfin in the 'Add Server Instance' dialog (vs. GlassFish) - SIP Servlet applications visible in the "Services" tab If you feel brave-enough to test the latest nightly builds, follow this link. As it stands, NetBeans 6.1 is stalled for the end of April. Previous coverage of sailfin is HERE.

Sailfin development is moving along quite well and the recently posted Public Review for JSR 289 (SIPServlet 1.1, one of the technologies implemented in Sailfin) is taking us one step closer to development of converged SIP/HTTP applications. Vince is reporting on the Module Suite for NetBeans 6.0 for SIPServlet development with Sailfin and the community involvement in that effort. NetBeans modules are available here and they integrate a SIP protocol level test agent.

Sailfin development is moving along nicely and so is it's tooling part now with SIP Application Development Module version 0.2 for NetBeans 6.0 and a detailed installation document. •  new is a "Converged Servlet Application" project template. •  full specifications are listed in this document. As detailed in this document, the next sailfin milestone build in December is Feature freeze.

Vince is working on the tools for SailFin and just released version 0.1 of a NetBeans 6.0 plugin starting with some earlier work by Ludo. Details in the writeup by Vince, including how to download the NB module. The full Functional Spec is at the GlassFish wiki and you can file issues (bugs and RFEs) here.

SailFin (the Communications/Telco Application Server) was Announced at Java One and we have reported since then on a couple of SIP applications: Click to Dial (full code available) and Conference Manager (soon available).

You can also read this intro to SIP, use this documentation to use a vanilla SIP proxy and SIPp to generate traffic, and use tooling support in NetBeans (development using Web Applications with the SIP Servlets Framework) as described here.

But maybe most importantly, nightly builds are now available from http://sailfin.dev.java.net/ (about 60mb, GlassFish runtime included). The first milestone is scheduled for August
