GlassFish at Lyon JUG

JUG's in France have been popping up here and there at an amazing rate in the past 18 months since Antonio and the team have started the Paris JUG. I think we're somewhere in the 12 JUGs or so. For a country that didn't have any really active one only 2 years ago that's just amazing.

I was down in Lyon earlier this week for a JUG meeting (this was only their third meeting) on Groovy and GlassFish where over 60 people showed up. Come to think of it, when adding up all the JUGs, I think we average about 1000 attendees very months, that's the equivalent of a pretty decent conference. The feedback I've received was pretty good. I did a demo-heavy presentation focused on GlassFish v3 (most importantly the modularity and extensibility) and the 30-minute Q&A session took me to demo v2 (Enterprise Manager), explain the pricing model and monetization strategy, discuss more generally the Java EE and app server statuses, and deflect the best I could some Oracle-related questions...

My slides are here and you can read some notes on the event here (in French).

Le clustering dans GlassFish (v2)

Baptiste me demande ou est passé le cluster "fantastique" (envolée du dimanche soir? :) dans GlassFish v3 Prelude? En réalité, cela fait partie des fonctionnalités qui ne sont pas encore intégrées dans cette nouvelle version de GlassFish et qui justifient de rester sur GlassFish v2 (si on exclu mod_jk, bien présent lui dans v3). L'ensemble des différences est résumé dans ce tableau comparatif.

Ce commentaire me donne l'occasion de mentionner le document récent de mon collègue Satya qui résume (et simplifie quelque peu) la mise en oeuvre du clustering dans GlassFish v2. Les retours habituels des utilisateurs: simple et administrable. A noter qu'il reste des choix à faire pour définir la topologie de déploiement la plus appropriée. C'est le sujet du récent "White Paper": "GlassFish HA Reference Config Guide" (enregistrement gratuit mais nécessaire).

GlassFish v2 UR1 available

Three months after the release of GlassFish v2, here comes GlassFish v2 Update Release 1 (UR1).

•  get GlassFish v2ur1 bits HERE (the official build is "b09b-fcs")
•  the equivalent Sun Java System Application Server version is 9.1_01 (download HERE)
•  it is also integrated in Java EE 5 SDK Update 4 (download HERE)
•  the plan was this: http://wiki.glassfish.java.net/Wiki.jsp?page=PlanForGlassFishV2UR.
•  Support options are HERE

Among the things you'll quickly notice:
•  need to use the -Xmx256m option at install time (it wasn't needed for v2 on some platforms)
•  Patch information (recently released patches for instance) and bug updates are clearly presented to the administrator (see also my previous post on the value of support as well as Anissa's short but effective screencast)
•  More exposure for the GlassFish Update Center

Also new with this release:
•  Some critical bug fixes, such as this one. Here's more information (over 200 total).
•  support for mod_jk sticky sessions in web container.
•  AIX operating system support. To be precise: AIX 5.3 64 bit OS and AIX 5.2 64 bit OS, on a 32 bit JVM. Only "developer" and "cluster" profile supported (that's full in-memory HA, just no HADB/NSS). No Load-balancer support.
•  SuSE Linux 64–bit support

Enjoy!
