Jarek Gawor is speaking at Apachecon 2010

I asked a few developers I know to answer three questions about Apachecon going on this week in Atlanta, Georgia. Jarek Gawor said...

What topic are you speaking about at Apachecon this year? What will developers learn from your session?

This year at ApacheCon I will be talking about Geronimo 3.0 and a set of OSGi enterprise specifications that Geronimo supports. In Geronimo 3.0 we redesigned the kernel to run on top of OSGi and integrated a number of OSGi enterprise technologies that enable building enterprise-level OSGi applications. Geronimo 3.0 also supports Java EE 6 technologies and together with the OSGi features Geronimo is a powerful platform for writing OSGi or Java EE -based enterprise applications. My session will describe the OSGi enterprise specifications supported in Geronimo, explain how they are integrated with the Geronimo framework, and show how Java EE applications can interact with OSGi applications and vice versa.

What topic are you most looking forward to learning more about or which speaker are you looking forward to hearing or meeting?

I work with OSGi a lot so there are a few OSGi-related sessions that sound interesting to me. For example, Carsten Ziegeler's “Just stay loose with OSGi and Apache Felix!” session or Marcel Offermans' “OSGi Design Patterns and Best Practices” talk.

What new feature of Geronimo v3.0 are you most excited about and why?

It is hard to pick one as there are a lot of cool new features introduced just as part of Java EE 6. For example, EJB 3.1 Lite or Contexts and Dependency Injection (JSR-299). However, I am mostly excited about the OSGi features we introduced in Geronimo 3.0 not only because they enable writing enterprise OSGi applications but also make extending or integrating new functionality into Geronimo much easier.

Thanks to Jarek for sharing a preview of Apachecon this week with us. Also read a preview from Zoe Slattery and Lin Sun, as well as Bob Sutor's keynote on Friday. If you are attending Apachecon next week in Atlanta, do reach out to our team. I wish I could be there with you for the big week. Have a good conference all.

What topic are you speaking about at Apachecon this year? What will developers learn from your session?

I'm giving two talks - one on behalf of Jeremy Hughes who sadly couldn't make it this year - and one of my own. The talk I've inherited from Jeremy is all about Apache Aries, why the project exists, what we mean by 'Enterprise OSGi Applications'. If you are a Java EE developer and what to know more about what you can do with OSGi this would be a good talk to come to. My own talk (A la carte OSGi) was really inspired by all the things I wish I'd known about a year ago - I'll go through a number of open source OSGi related projects explaining what they are useful for and how they are related to each other. If you are at the point where you get the modularity message and are ready to dive into coding this talk could save you some time.

What topic are you most looking forward to learning more about or which speaker are you looking forward to hearing or meeting?

I'm looking forward to meeting people that I've never met face to face but have worked with - both in IBM and at Apache. I'm looking forward to hearing about almost everything - the hardest thing is working out which sessions to go to out of the many that I want to attend.

What new feature of Geronimo v3.0 are you most excited about and why?

Well, that would have to be the Enterprise OSGi capabilities, of course.

You can read Zoe's blog Zoom splatter and follow her on twitter @Zoe_Slattery. Reach out to her at Apachecon. Also read a preview from Geronimo developers Jarek Gawor and Lin Sun.

See you next time,

Perspectives and Observations from the New JavaOne

I have not been to the JavaOne conference since it's heyday back in 2001. Java had it's time in the, ahem, Sun, and now we are all wondering what it will now be like to experience this annual gathering co-located as an Oracle developer confab. My California based manager Sunil Murthy had the great opportunity to participate at JavaOne 2010 / Oracle OpenWorld, experience the new Java conference and meet developers and thought leaders in our industry. I posed the following questions about the conference in September.

Hey Sunil, I trust you are rested up from the grueling conference schedule. I wonder what was the atmosphere like this year with the Oracle led event?

With all the walking between hotel locations of keynotes and Javaone camp, yes absolutely Ryan! I believe folks appreciated the technical content that is signature Javaone and also the surprising level of technical details that Larry and Thomas provided in their respective keynotes. I'll point to a couple of key take-aways that stood out. First and foremost is Oracle's entry into cloud computing aligned with Amazon EC2. Second, the Java roadmap, highlighted by Thomas Kurian's keynote, seeks to reinvigorate Java innovation with an Oracle "stamp." I did, however, gather from my own impression as well as in talking to folks, that the Java development community is "thirsty" for a vendor neutral forum, as was widely discussed in various forums.

What bits would you share from the cloud computing announcements?

After dismissing cloud computing last year, Oracle was all over cloud computing during the conference. The keynotes touched on "what is cloud computing" based on Amazon's EC2 definition, and made it abundantly clear on not aligning with the Salesforce.com view.

Which technical talks were most interesting for Java developers about future directions?

In my view, there were seemed to be a big focus on modularity, new programming models, new languages and of course mobile frontiers - isn't there always? ;) There was good talks about a modular java platform Jigsaw. There is ever increasing interest in the language Scala on the VM, but I can't tell if Scala is the new Ruby or not, if you know what I mean? There was also a talk about hybrid OSGi and JEE programming model of note to our team.

Surely there was talk about the front end?

Oh yes, how could I forget. There was a lot to do about ease of use with JavaFx and the demo was fantastic! Check it out on YouTube. There is Java, JavaScript and HTML5 support, with the claim that HTML5 is strategic. Native client runs on HotSpot and JavaFx is common across browser and native client. Very cool stuff.

What did you learn from discussions with developers in the Java community?

Really there is a lot of concern about the direction of the community but there is also a lot of optimism. Java is a growing developer community that is only becoming more specializing with the platform growing into areas like mobile with Android and gaming. There is concern over the JCP, but the Java developer community is 9 million strong and the marketplace is vibrant with healthy competition. Enterprise Java is a mature platform but it is evolving and changing.

Thanks for sharing your JavaOne 2010 observations with us Sunil.

Until next time,

Ryan Boyles

IBM Open Source talks and topics at JavaOne 2010

I wanted to share a few open source related talks I know of where IBMers are speaking at JavaOne 2010. The topics are focused on the JPA, OSGi and SCA, which enable developers using WebSphere Application Server through add-on feature packs. I interviewed an IBM software architect Kevin Sutter on this topic last week.

Pinaki Poddar will be presenting a session on Scale Java Persistence API Applications with OpenJPA Slice (S314445) in the Java EE Web Profile and Platform Technologies track on Wednesday September 22nd at 4:45PM PDT. The JavaOne blog featured the entire list of Open Source sessions. Pinaki is an OpenJPA committer and also blogs on the WebSphere Persistence blog.

Next up, Alasdair Nottingham is speaking about Creating Modular Applications with Apache Aries and OSGi (S313866). The talk will cover the Apache Aries project (designed to bring modularity of OSGi together with the Java EE platform) and will feature a look at creation of new applications using Apache Aries and the OSGi Blueprint container. Alasdair is @notatibm on Twitter and blogs with other IBMers on the WebSphere Community Blog. Catch up with Alasdair on Thursday the 23rd at 3:30pm.

On the SCA side, Jean-Sebastien Delfino of IBM and Luciano Resende of Shutterfly are giving a talk about Developing Composite Applications for the Cloud with Apache Tuscany (S314011). Luciano blogged about this session already.

Finally, BJ Hargrave will be hosting a Birds of Feather roundtable on OSGi with aQute CEO Peter Kriens (S313877). BJ is an IBM Senior Techical Staff Member, CTO of the OSGi Alliance and a committer on the Eclipse Equinox project, an open source OSGi implementation. Find this BoF at 6pm on Tuesday the 21st, look for @bjhargrave and @pkriens.

Oh wait - there is more! Last one, I promise. How can we leave out Cloud?! Doug Tidwell has a talk about cloud: Keeping Your Options Open, Even If the Cloud Is Not. Find @Doug_Tidwell Wednesday at 4:45.

IBM.com has a couple of handy webpages showing all of the IBMers at the somewhat co-located JavaOne / Oracle OpenWorld conferences. My emerging technology evangelism team manager Sunil Murthy @SunilBayarea will also be in attendance during the week. Seek out these smart folks and follow the conference backchannel via twitter with hashtags #javaone10 and #oow10. The IBM Booth is #1111. Apparently IBM is giving away "Sweet Tweet Cupcakes" - get your sweet fix. IBM also has a mobile web app for your use at OOW. Last but not least, there is also an ILOG booth #5104. They'll be talking about Visualization with Java.
