GlassFish Back from Devoxx 2011
Mature Java EE 6 and EE 7 well on its way

I'm back from my 8th (!) Devoxx conference (I don't think I've missed one since 2004) and this conference keeps delivering on the promise of a Java developer paradise week. GlassFish was covered in many different ways and I was not involved in a good number of them which can only be a good sign!

Several folks asked me when my Java EE 6 session with Antonio Goncalves was scheduled (we've been covering this for the past two years in University sessions, hands-on labs and regular sessions). It turns out we didn't team up this year (Antonio was crazy busy preparing for Devoxx France) and I had a regular GlassFish session. Instead, this year, Bert Ertman and Paul Bakker covered the 3-hour Java EE 6 University session ("Duke’s Duct Tape Adventures") on the very first day (using GlassFish) with great success it seems. The Java EE 6 lab was also a hit with a full room of folks covering a lot of technical ground in 2.5 hours (with GlassFish of course).

GlassFish was also mentioned during Cameron Purdy's keynote (pretty natural even if that surprised a number of folks that had not been closely following GlassFish) but also in Stephan Janssen's Keynote as the engine powering Parleys.com.

In fact Stephan was a speaker in the GlassFish session describing how they went from a single-instance Tomcat setup to a clustered GlassFish + MQ environment. Also in the session was Johan Vos (of Mollom fame, along other things). Both of these customer testimonials were made possible because GlassFish has been delivering full Java EE 6 implementations for almost two years now which is plenty of time to see serious production deployments on it.

The Java EE Gathering (BOF) was very well attended and very lively with many spec leads participating and discussing progress and also pain points with folks in the room. Thanks to all those attending this session, a good number of RFE's, and priority points came out of this. While this wasn't a GlassFish session by any means, it's great to have the current RESTful Admin and upcoming Java EE 7 planned features be a satisfactory answer to some of the requests from the attendance.

Last but certainly not least, the GlassFish team is busy with Java EE 7 and version 4 of the product. This was discussed and shown during the Java EE keynote and in greater details in Jerome Dochez' session. If any indication, the tweets on his demo (virtualization, provisioning, etc...) were very encouraging.

Java EE 6 adoption is doing great and GlassFish, being a production-quality reference implementation, is one of the first to benefit from this. And with GlassFish 4.0, we're looking at increasing the product and community adoption by offering a pragmatic technical solution to Java EE PaaS deployments. Stay tuned ! (the impatient in you is encouraged to grab a 4.0 build and provide feedback).

A day @ Devoxx, all about Java EE 6

My first day at Devoxx was exhausting but quite satisfying. Our "Java EE 6 Tutorial, reloaded" session went very well, with all 15 demos working flawlessly, including the 4 new client demos, new slides for CDI, a "Gotchas" section and an overall pass on the slide deck. The feedback (questions, discussions, tweets, ...) was very good and many asked about the address for the demos, so here it is: http://beginningee6.kenai.com/ (code is in the trunk, we'll tag it soon). The slides are here.

In the afternoon, Antonio and myself decided that three hours of talking wasn't enough so we took on to run a Hands-On Lab for another 3 hours. This was another set of reasons for satisfaction: 40+ people (full room) with no one leaving because of technical issues (quite rare in HOLs) and lots of good conversations comparing NetBeans to other IDEs, JSF to Struts, CDI/EJB to Spring, etc...

Overall it seems people attending were happy going through the (admittedly simple) three exercises on JSF, JAX-RS, and CDI. Those exercises and the instructions document are available from this URL. Check the README.txt file which will tell you which projects to use (with or without Maven).

Of course, as always, lots of familiar faces and fun discussions. Now looking forward to the keynote sessions tomorrow (JavaSE) and Thursday (JavaEE).

Javaholics Unite (at Devoxx 2010) - a Java EE perspective

Devoxx 2010 is starting in a few hours and I'll be on the train tomorrow to Antwerp. I'll have a pretty busy schedule with a tutorial, a hands-on lab, and a BOF.

So this year again, I'm giving a Java EE 6 Tutorial with my friend Antonio Goncalves. We called it "reloaded!" for a reason: it is not a repeat. A lot has happened in the past 12 months: Java EE 6 was released (and GlassFish had 3.0 and 3.0.1 releases), Oracle finally acquired Sun, CDI is getting traction, vendors are delivering, and to be bluntly honest, we've made progress in our understanding of the platform. So expect demos (including a number of new ones), new topics (mainly CDI), putting Java EE 6 portability to the task with an additional runtime, and a few new fun things. The session is at 9h30 on Tuesday.

Devoxx is having Hands-On Labs for the first time this year and attendees will be able to attend a self-paced, Java EE 6 Lab on the Tuesday afternoon which would be a great follow-up to the morning session. The only requirement for this is to come with a laptop with NetBeans 6.9.1 (java version with GlassFish) loaded (no more Maven required, it's just a bad idea with conference wifi). The rest is in the instructions we'll hand out at the beginning of the session. I'll blog after the conference about where you can find everything to work through those three exercises and get you feet wet with Java EE 6.

In other Java EE 6 festivities from fellow colleagues :
• Paul Sandoz will be able to discuss how JAX-RS integrates with the rest of the Java EE platform as well as present content from the recent JSR proposal for JAX-RS 2.0 (packed with useful stuff IMO).
• Linda DeMichiel will cover JPA 2.0 (I tend to learn something new every time I hear a JPA 2.0 talk) and a more advanced talk about the Java Persistence Criteria API.
• GlassFish architect Jérôme Dochez will cover the HK2, multiple-purpose kernel in his "HK2: Oracle WebLogic Server, Oracle GlassFish Server, and Beyond" session and will, of course, lead the GlassFish BOF.
• Ludo will cover the tooling aspects comparing NetBeans, Eclipse and IntelliJ when it comes to supporting the Java EE platform today.

They will all be giving the Java EE future keynote on Thursday morning.

There are many more interesting server-side sessions from the guys at JBoss, a must see performance by Adam Bien, a couple WebSockets presentations [1], [2], some OSGi talks, and a lot more.

Beyond the (almost) mandatory "Future of Java" and other JDK 7 talks, I'll also try to hit the NoSQL, Cloud and DevOps sessions, time and socializing permitting.

Java2Days 2010 : server-side heavy, with still all the fun

I'm back from Sofia and another java2days conference. As it was the case last year, the agenda was pretty heavy on server-side content with Java EE, Spring, CDI, and cloud-related talks. This year the conference also had two additional tracks to cover mobile and cloud (not sure how those went, I was busy preparing slides and attending sessions in the bigger room). I was presenting on Java EE 6 adoption and OSGi for GlassFish and Java EE developers. Both sessions had great attendance and a good set of questions (after the talk since 45 minute-sessions made it really hard for me to leave time for Q&A). The SAP folks in particular (large team based on Sofia) had a number of questions around OBR, P2, Felix vs. Equinox, etc...

I enjoyed meeting Reza Rahman again who seems to be working hard on passing the Java EE 6 Web Profile TCK for Resin. Reza presented on CDI, testing Java EE (which I had very much enjoyed at JavaOne) and an informative talk on how the JCP works. Arun has more details on the speaker's diner which, as always, was one of the highlights of the conference.

While I didn't attend the other tracks, I had interesting discussions with James Ward (Adobe), Andreas Jakl (Nokia), George Reese, Josh Long (now at VMWare/SpringSource), Vladimir Pavlov (SAP), Katya Todorova (SAP), Werner Keil (JCP EC member) and was happy to meet again with Andrew Lombardi, Talip Ozturk, Vassil Popovski, ... I even did a podcast with Damon Edwards & John Willis some 24 hours after hearing the term "devops" for the first time (yes, I've been living in a cave).

With 500 attendees, I think this was yet another great conference. Let's have some more Java SE content next time (there will be plenty to talk about in 12 months)!

Back from Brazza

I was fortunate enough to visit Congo Brazzaville (just celebrating their 50 years of existence) to present at the jCertif conference, probably the biggest Java event in central Africa. I was expecting an adventure and an experience. I wasn't disappointed. So of course this is Africa and I probably shouldn't be surprised to see children cross the runway only seconds after the plane had landed. The food (fish, meat, chicken and bananas!) was great and the crowd welcoming. I had had a taste of what to expect when chatting with Max Bonbhel, the organizer of the conference, a leader of the CongoJUG (great logo btw), and overal an entrepreneur.

Max had arrived a week early (he lives in Canada) and had to find a venue, sponsors and take care of all the logistics. He did great with the event finally taking place in the National Center of Congress with the support of the ministry of New Technologies and major telcos as the sponsors. He also managed to get the two of us to appear for an interview on national TV the day I landed to promote the event (and our respective topics).

Congo Brazzaville seems to be, like other countries in this part of Africa, (finally) experiencing a shift to broadband with a fiber backbone coming up in 2011 and the younger generation starting to slowly take advantage of the new IT opportunities this will bring. Infrastructure is still a big concern with the capital city still experiencing unplanned and \*planned\* electricity outages (not a good idea to be in the elevator at that time). For anyone telling me that Internet access and bandwidth are no longer a problem anywhere in the world, I can now share that downloading a 50MB GlassFish archive will take a good 8 hours (download size does matter here, CDs are welcome), that SVN worked sporadically for me (if at all), and that watching streamed video is just not an option. Internet access is still very expensive and you are asked to think twice about bandwidth. This obviously makes it still a bit hard to do business on the Internet but with infrastructures improving by the day the country is waking up to the possibilities.

The conference itself was held in an impressively large room which I understand is where the parliament meets. Access to the conference wasn't free but costed only about the price of a softdrink. About 300 people participated, some coming from neighbor Congo (CDR), others flying from Togo, Kenya and other countries. Max kicked off the day with a talk about web 2.0 and the impact it will have from a social, technical and business point of view. Mike Levin (freelance consultant, Swampcast podcast, codetown.us, ...), straight from Florida and also a JUG-addict (he runs no less than 4 JUGs) then got down to some more details about the technical building blocks of web 2.0 development. It was great to meet Mike (we stayed in the same hotel) as I could help him with his French (the official language here) and he'd teach me the lingala (local dialect) words he had learned (Keetoko!). We also found out that we had a great deal of people in common. Check out his post about the conference.

The next speaker was Horacio from Togo talking about Talend. His talk was a great balance with a few slides to set the stage on ETL's and about a half an hour demo which is usually too long for people to follow along but this one progressed very nicely. I then presented on Java EE and GlassFish (slides), trying to start slow for the people that hadn't used it before but also covering Java EE 6 new features for the more advanced crowd (I got some pretty advanced questions during lunch). Finally Stanyslas from Kinshasa presented the NetBeans platform for building rich applications and in particular the RAMS (Refugee Assistance Management System) application he's building for the United Nations' HCR (refugee organization). A good didactic talk, NetBeans Platform extraordinaire Geertjan would have been proud!

The event continued for another 3 days of training and preparation for the Java Certification. This is free training and the deal is that if you attend (80 people showed up on the first day) you need to train others yourself in the next 6-9 months. This is just a moral obligation and training a couple of people over a few hours is good enough. I think this is a great initiative and a great way to build communities, something that feels pretty natural to the people I've talked to while in Congo Brazzaville.

While writing this it occurred to me that I've now traveled to all main continents (still working on Antartica) to talk about GlassFish!

Atmosphere jeudi, Devoxx lundi

Pas le temps de respirer, demain Jeudi Jean-François Arcand sera là au ParisJUG pour vous donner un cours de bon français et pour vous parler d'Atmosphere, le framework multi-serveur pour faire du Comet (AjaxPush). Il y sera également question de comparaison avec Servlet 3.0 (ne pas oublier de s'inscrire, il doit rester des places).

Lundi, direction Anvers pour la conférence Devoxx. J'y présente avec notre Antonio Goncalves national (enfin c'est surtout lui qui fait le gros du boulot!) une session de trois heures sur Java EE 6 (dont les JSR sont approuvées les unes après les autres ces jours-ci). Entre consolidation des slides, mise au point des démos, et ajouts de dernière minute, on n'est pas tout à fait près...

Avec servlet 3, managed beans, bean validation, etc... cette session ira clairement au delà du contenu du bouquin d'Antonio (pourtant déjà très riche). Reste la question du JSR 299 qui mérite une session à lui tout seul (difficile de ne faire qu'une intro, la technologie a un ticket d'entrée non négligeable). En tout cas je trouve la progression dans la douzaine de démos plutôt sympa (une idée d'Antonio).

Pour ce qui est du contenu GlassFish (keynote, sessions, etc...): les détails sont ici.

Attending and presenting at Java2Days this week in Sofia

I'll be attending the Java2Days conference at the end of this week in Sofia, Bulgaria.

The conference is quite geared towards server-side Java with Spring and Java EE getting great coverage with SpringSource employees and Java EE expert group member Reza Rahman.

My first talk on Thursday is on GlassFish v3 while the second is on portability of J2EE/JavaEE applications (lessons learned while migrating customer applications to GlassFish). Should be fun!

"Le futur de Java" ce jeudi à l'OpenWorldForum

Ce jeudi, vous êtes conviés à venir à l'Open World Forum qui se tient à Paris (Eurosites George V dans le 8ème) et en particulier à la series de courtes sessions autour de Java.

Avec l'imminence du rachat par Oracle de Sun, un point sur Java semblait intéressant et utile. Au programme, le chemin parcouru par Java SE depuis sa mise en Open Source et les avancées prochaines de JDK7, une table ronde sur les langages dynamiques sur la JVM (Groovy, Scala, Fan, et Clojure, ou Jython, JRuby et PHP?), et enfin un point sur Java EE 6 et son implémentation de référence GlassFish v3. Notre Guillaume Laforge sera de la partie pour la table ronde.

Ce sera bref (1h30 au total), mais une occasion concrète de faire le point sur les travaux en cours et sur ce que le futur proche nous réserve.

• Programme: http://openworldforum.org/program/floss-java.
• Enregistrement, c'est ici: http://openworldforum.org/Register.

GlassFish v3 at JavaZone - slides, demos and screencasts

Here are the slides that I presented on GlassFish v3 at the JavaZone conference today. All five demos went fine (some with the help of the audience), and I even got questions at the end. I'm not sure what the plans are for making the conference talks available (delay, format), so here are the five demos (almost identical) in various screencasts :

Painless development with GlassFish (deploy on change, session preservation, etc...). Use it today on any GlassFish v3 install.
Painless Java EE 6 development (James Gosling himself, only using NetBeans, not Eclipse like I did). Starts at 12:21. Same as above - any v3 version.
• GlassFish à la Carte - Part 1, Part 2, Part 3 (the closest to what I showed) - Same as above, IPS has been there from day one (much improved in recent builds though).
Extending GlassFish v3, OSGi-style (by Jerome Dochez, the GlassFish architect), note that recent promoted builds of GlassFish v3 now ships with the Felix OSGi declarative service bundle by default, no need to install it manually.
• (I don't know of a screencast showing the RESTful admin, but Rajeshwar blog would be a good start and Ludo's JavaFX demo a fun illustration). Using recent promoted builds is recommended.

Update: the video is available (streaming + QT format). Demo timing are documented here.

Let's enjoy the rest of the conference now...

GlassFishZone in Oslo

I'm flying out to Oslo in a few hours to present at JavaZone on GlassFish v3. The slides and demos are now ready. This talk will focus exclusively on v3 and a bit of Java EE 6 (just can't do justice to it in the little time that I have). I had initially listed 7 demos but quickly found out that this would be way too much to cram into the 1-hour slot, so there's only going to be 5 fairly short demos (tooling, Java EE 6, packaging, OSGi, and RESTful admin). Let's hope they all go well ;)

Since this is partly new material and certainly has some new demos I wanted to test-run this in terms of timing and sequencing of demos. So I presented this yesterday at work to several colleagues and it's amazing how much you learn by presenting it just once. Ideally I would dry-run every presentation but it needs to feel a little real with somebody listening or else I just don't get into it. Anyhow, I'll be using a shorter version for the conference but the slides I'll post will have more details.

Session details:
"GlassFish v3 - The future of app servers and Java EE is here... well almost"
• Sep 9th, 14:15 - 15:15
• Room: Sal 3

As always, the agenda is diverse (with some usual suspects) and there's is a number of sessions that I'll try to attend (conflicts preventing) - EJB 3.1, Google App Engine, Ioke (Ola Bini's new language), JSR 330/Guice (that one is in parallel with my session unfortunately), developing for the cloud, class-loaders, hudson (Kohsuke will be there, I'm sure that his session will be packed and that there will be people talking to him hours after he's done ;) , debugging your production (btrace, ...), and more. But if the organisers still have those headphones in the main room with sessions showing in parallel on 6-7 screens I might do the usual zapping (not very nice to speaker I must admit).
