After a short break, it is time to restart the "Heroes of Java" series. This time it is kind of an unexpected hero.

I don’t like to go into too much detail about security updates, but I think it’s necessary to point out a few facts about the one we released yesterday, given some of the inaccuracies I’ve seen been spread on Twitter and elsewhere. Patches were belatedly approved for OpenJDK 7u. OpenJDK 6 is not affected...

I don’t think we will see a “winner” of the browser-language wars any time soon, but there will be a winner. JavaScript hype is still through the roof, and with the discovery of a dynamic language in the browser that actually works decently between late browsers, people are thoroughly excited; however, I’d akin this to people discovering Perl during the advent of C and C++. Does it work?...

It has been almost exactly three years since Java EE 6 and GlassFish 3 were announced. It's worth pausing a moment to take stock of what has happened since. Both Java EE 6 and GlassFish 3 have been game changers. EE 6 has brought Java EE back in the limelight. To see evidence of that look at presentations like these from independents like Bert Ertman and Paul Bakker...
