The vast majority of Tomcat applications ran fin on GlassFish. Jan tell us that now even the ones using the Tomcat-style valves will run unmodified. Of at The ServerSide Pawan explains How to use OpenMQ with Mule ESB by configuring the Mule JMS connector. Added (by pelegri) - I've heard of a number of requests for this, please let us know if you use the combination so we can track OpenMQ adoption. LayeredTech announced free GlassFish hosting for Sun Startup Essentials™ Program participants. CrazyRails has a post on how to install JRuby on Rails on Mac, including GlassFish and MySQL setup. More GlassFish coverage is promised.

OStatic (part of the GigaOM Network) is a social network to find, evaluate and collaborate on Open Source Software, and they have a Promo Offer for 12 free months of hosting of GlassFish Server and MySQL Server. Also see other GlassFIsh Hosting TA entries.

Rimuhosting now Supports GlassFish. Their application came just a bit too late to make it into the formal GlassFish Partner Showcase but they will be added early next week, when we are all back from JavaOne.

WebAppCabaret now provides support for GlassFish. Check out the Private JVM or the VPS offering - the GF-specific page is here. I am collecting a list of hosting providers that support GlassFish. Please let me know if you are such a hosting provider and we will advertise it.

And, if you let me contact me ASAP, I might still be able to list you in my slides for our CommunityOne KickOff Session.

A while ago we had a thread on Where to Host Java Apps. Several people suggested using Virtual Private Servers (VPS) (Wikipedia) and mentioned that some vendors already supported GlassFish and others were getting ready to do so... and eApps just did that. eApps's VPS solution uses Virtuzzo (from Parallels) and is described in detail here. The details for GlassFish Support and the pricing/features seem quite good. Check it out and post your experiences. And, if let us know of other hosting solutions for GlassFish we will mention them here too.

Upgrading can be troublesome and human being are reluctant to change by nature, but sometimes it's just too good to miss out. Glen Smith is reporting why and how HTTP Compression Support and much improved virtual domains made the difference for him. If you're concerned with preserving your GlassFish configuration, you should read Shalini's GlassFish upgrade story.

Other new GlassFish v2 Web Container features (Comet, WebDAV, SSL non-blocking nio, Asynchronous Request Processing and a lot more) are listed here. While Grizzly and more generally the Web Container have had substantial improvements, Clustering is probably the most important new feature in GlassFish version 2.

Whatever your favorite feature, make sure you try the beta version and report your experience.

Joyent is an interesting company that provides traditional Web Hosting but also Web 2.0 applications as well as on-demand computing. Joyent seems to use OpenSolaris so perhaps it is not too surprising to read John's report from the JavaOne floor that they are offering GlassFish hosting. One more indication of the adoption of GlassFish; this year's JavaOne is full of them...

Jan and the Web Tier team have been adding a number of very useful features for virtual hosting to GlassFish v2. Virtual Hosting is very convenient even in the small, but it is a must for ISPs and ASPs. Features include Isolation Levels, Root Context Configuration, Alternate DocRoots, Security and Dynamic Reconfiguration. Jan covers all of these in his very detailed blog; check it out. BTW, I've been busy elsewhere in the last few days (including almost 2 days here) and I have a big backlog; I'll try to catch up in the next few days before the Holiday break arrives.
