Mark Wielaard: New GPG key.
Finally created a new GPG key using gnupg. The old one was a DSA/1024 bits one and 8 years old. The new one is a RSA/2048 bits one. I will use the new one in the future to sign any release tarballs I might create. pub 2048R/57816A6A 2011-01-29 Key f...

Web Sockets and HTML5 in Glassfish
It's been several months since my last blog! I have recently re-joined the Glassfish team at Oracle and I'm currently looking at Web tier technologies like Web sockets and HTML5. In this blog, I'd like to show you a simple Web application in which you can control an HTML5 video object remotely. The basic idea is to intercept video events like 'play', 'pause' and 'seeked' and remote them using Web Sockets to control another player. Although there may be some use cases for an application like this (such as coaching), the real objective of this exercise is to show the low latency of the Web sockets implementation in Glassfish. So let's get started!
Here is a screenshot of the application:
A Web socket is nothing more than a socket connection that can be established between a (modern) Web browser and a Web container. It provides a low-latency, bi-directional communication "parallel" to the HTTP channel. It is Ajax/Comet on steroids. No hacks, no jumping through loops, nothing. It has the potential of redefining what we understand as a Web application lifecycle given it's low latency and always connected characteristics (but more about this on a future blog).
Our Web application comprises of a single page and some JavaScript code. We use JSF 2.0 facelets to define the main page:
