Tampa Java User Group

Hello Java Group Memebers,
The June 2009 meeting will be about increasing productivity by reducing the time of your Java build/deploy cycle.  If you’ve built medium to large scale Java applications (JEE, stand alone, desktop, etc), then you are familiar with the drudgery of building and redeploying your entire code stack due to a minor change.  It’s
tedious and can consume an average of 2 to 5 minutes of your day.  In this talk, speaker Jevgeni Kabanov, of Zeroturnaround Inc, will highlight three approaches you can use to decrease your turnaround
time during the build/deploy cycles and save at least one hour daily.

“Watching the logs roll by” - AKA “How to stop waiting for build/ deploy and enjoy coding again”

25 percent of developers say that their JEE projects take over two minutes to deploy, every time they want to see their changes. Over 70 percent say it takes at least a minute.  Since on average we deploy five times an hour, we are watching the logs roll by, or switching to email and losing focus, for 10-40 minutes every day.

In this talk, Jevgeni Kabanov will highlight three key techniques that you can start using immediately to drop the time from hitting Ctrl+S to refreshing your browser — down to less than one second. We will start by discussing exploded development and some shortcuts you can take to eliminate the build scripts from your everyday life. Then we will review some ways to bypass or speed up redeployment. We will take a look at JEE redeployment, OSGi modules, special framework support that exists in Grails, Seam, Tapestry5 and RIFE, and JVM HotSwap. We will cover what you can do for free, and introduce a class reloading JVM plug-in called “JavaRebel”, that solves the problem for peanuts.

After this talk, you will leave with a clear idea of at least three ways to reduce your turnaround, and measurably save your team at least an hour per day.

For the Tampa Java User Group’s May 2009 meeting, we will take a look at distributed application development.  With the momentous rise of cloud computing, distributed programming tools  are becoming valuable assets to developers.  In our next meeting, we will have a presentation on Hazelcast by Talip Ozturk (creator), an open source data clustering framework for Java.

As always, if you plan to attend, make sure to bring a colleague.  An RSVP email will be sent later, so be sure to respond so we can plan accordingly.  There will be food and plenty of prizes and giveaways.

-= Presentation =-
Today’s applications are getting more and more distributed everyday and it is well-known that distributed programming is hard. With Hazelcast though, distributed programming is easy and lots of fun. Common reaction of Hazelcast users is ‘Ooh my God, this cannot be that easy’. Hazelcast is an opensource transactional, distributed/partitioned implementation of queue, map, set, list, lock and executor service for Java. Hazelcast is for you if you like to easily:
* share data/state among many servers (e.g. web session sharing)
* cache your data (distributed cache)
* cluster your application
* partition your in-memory data
* send/receive messages among applications
* distribute workload onto many servers
* take advantage of parallel processing
* provide fail-safe data management

In this session, we will cover:
* Introduction to Hazelcast
* Code samples
* Use-cases
* Demo
* Internals of Hazelcast
* Q/A

Talip Ozturk is the founder of Hazelcast and Hazel Ltd. He has been working with enterprise Java since 1999. In 2003, he got fascinated by Jini and developed an implementation of JavaSpaces. In 2008, his
passion for distributed programming led him to develop Hazelcast, an open source clustering and highly scalable data distribution platform for Java. Before Hazelcast, he was the director of technology at Zaman

For March 2009, The Tampa Java User Group will hosts another great meeting investigating the use of the Spring Framework’s dynamic language.  With the growth in popularity languages such as Groovy, Ruby, Python, etc JSR-223 introduced inherent support dynamic languages on the VM via the Scripting API.  In the next meeting, speaker RJ Salicco will explore how to integrate scripting  into your own Java developmen using the Spring Framework’s support for dynamic languages.

You will receive a RSVP email (to follow later) to confirm your attendance so we can plan accordingly.  Arrive early and bring a colleague to enjoy this great topic.  There will be food and plenty of giveaways.

-= Presentation =-
With the growing popularity of dynamic languages like Groovy and Ruby, speaker R.J. Salicco will discuss and demonstrate Spring’s support for dynamic languages inside the Spring container. The presentation will cover a quick introduction to the basics of the Spring Framework and explore the followings
* how to create a Spring POJO backed by a dynamic language
* How to use the <lang:language/> Spring configuration tag to declare your dynamic bean
* Refreshing dynamic beans at runtime without restart
* Wiring and injecting values into dynamic beans at runtime
* Use case scenarios such as MVC controllers, validators, and lightweight business objects that can change dynamically at runtime to accommodate an agile environment.

The Feb 2009 meeting was quite a success.  We had food, drink, and learned about OSGi.  Speaker Vladimir Vivien provided an introductory summary about OSGi, definition, how it’s used, and it’s role in the Java stack. There were plenty of code samples ranging from the simple HelloWorld to a demo that showed how to use OSGi bundles to handle file types.

Hello Tampa Java Enthusiasts!

For February 2009, The Tampa Java User Group will host an introductory meeting about OSGi.  You may have heard about the technology and wondered “OSG-what, what is that?”.  In this presentation, speaker Vladimir Vivien will provide an overview of OSGi and help you understand how this Java technology is impacting the industry (see presentation details below).

Use the RSVP email (to follow later) to confirm your attendance so we can plan accordingly.  Arrive early and bring a colleague to enjoy this great topic.  There will be food and plenty of giveaways.

-= Presentation =-
OSGi is emerging as the technology of choice for creating and deploying modularized Java code.  However, as we will see in the presentation, OSGi is much more than that.  It is a proven and tested set of specifications and implemented libraries that are primarily designed to (not only) improve code modularity, but also solve runtime jar dependency issues, provide a formidable ecosystem of tools that augments OSGi to make development easier.

Presentation topics will include

- Introduction to OSGi
- OSGi Runtime Containers
- Creating An OSGi-based Bundle (jar files)
- Enterprise Java and OSGi
- Future of OSGi

2009 started with great success with the ReadHat/JBoss presentation.  We had about 41 attendees showed up to network, socialize and learn about JBoss SOA tools.  Presenter Kevin Barfield walked the audience through the summary of service oriented architecture and provided an overview of technologies available to facilitate integration efforts such as JBoss ESB.  There were plenty of examples and three Seam books were given away to our lucky winners.

Once again, it’s that time to close out another successful JUG year!  We’ve  seen everything from Hibernate, Grid Computing, to Flex.  This last meeting is just Wings and Beer.  I know it’s (really) last minute and I apologize,  however, it would be great if you can join us tomorrow at Wing House on Hillsborough Ave for the last Tampa JUG meeting.

If you can make it, just show up, otherwise, we will see you in January next year!

A great thanks to all of you who attended the November 2008 meeting on Java concurrency last Tuesday, Nov 18th.  This time the meeting’s format was different: we all got to see Grails in action live from presenter RJ Salicco.  We walked through the development of a basic web application complete database, onfiguration, and GUI in about 1 hour.  Some attendees brought their laptops and participated right along with the presentation.

Looking forward to another exciting year in 2009.  Stay tuned!
