In the opening keynote of Day 2 (Day 1), Joe Ottinger, Editor-in-chief of TheServerSide, asked the following questions, to an audience of approx 500 Java developers, receiving instant feedback using little handy devices on each attendees table. As with any surveys, the data may be skewed because of multiple reasons (not all participating, voting twice, pressing the wrong key etc). But here are the questions and their answers:

Which languages do you use most often ?

I could not capture the exact percentage but the priority order is listed below. This being a Java conference, the percentage for Java developers is well expected.

Which version of JavaEE API do you use ?

How do you call Remote services ?

I gave a talk on JAX-WS and WSIT: Tangoing with .NET yesterday and it went well. The two demos in the talk are also available as screencast in #ws1 and #ws3. I always leave time for Q&A and this time the discussions were way after the session was over. And I like it that way :) The key message is WSIT, available in GlassFish v2, gives you first-class interoperability with Microsoft .NET 3.0 framework and comes with fully integrated development experience in NetBeans 5.5.1 IDE.

I enjoyed a panel discussion on "Open Source Business Panel" and there were representatives from Alfresco, JBoss, SpikeSource, LifeRay, Interface21. The monetization model for all the participating companies was by selling professional services, technical support and training. Sun Java System Application Server (product version of GlassFish v2) offer training, services and support. Read Ed Ort's detailed summary of the session here.

I spent the afternoon with Joe Ottinger, Editor-in-chief of TheServerSide.com, deploying a trivial deployment-descriptor-free Web service on GlassFish v2. Basically we used the instructions as I described in an earlier entry. He was using GlassFish v2 b33 and was not able to get it working. On my laptop, with v2 b39, the service deployed easily. And even with b33 it worked. Anyway, Joe is going to install a fresh copy of b33 and try it. He also gave some good feedback in terms of how java.sun.com/webservices should be structured. We are already working on cleaning up the website and you'll see the changes in the weeks to come.

I spent the evening walking on the strip and took bunch of pictures.
