GlassFish 3.1 Is Now Available

This new release brings in a myriad of features, the most significant of which is probably clustering and high availability. The Aquarium is the best place to find links to blogs, screencasts etc. from various GlassFish engineers (though Markus Eisele has a nice run down of the new features here as well). The Aquarium’s list is pretty extensive, so certainly check it out, but I’d like to highlight a few that I found interesting from teammates of mine:

People often ask what the difference is between the free GlassFish and the commercially-supported version. The answer really is "not much" in terms of the core server itself (pretty much just branding changes). The commercial version, though, has some nice value-add features, such as the Performance Tuner, amongst others.

I’m really, really pleased with how GlassFish 3.1 has turned out. We still (and will always) have more work to do, but this is a solid release that finally fills in some enterprise holes that v3 didn’t have time to fill. Download it, install it, kick the tires a bit, and tell us what you what you think. In the meantime, we’re going to go ahead and get started on 3.2.
