Thinking in Language
Posted by: Ted Neward on 05/09/2008

Ted Neward
A couple of folks have taken me to task over some of the things I said... or didn't say... in my last blog piece. So, in no particular order, let's discuss. A few commented on how I left out commentary on language X, Y or Z. That wasn't an accidental slip or surge of forgetfulness, but I didn't want to rattle off a laundry list of every language I've run across or am exploring, since that list would be much, much longer and arguably of little to no additional benefit.... more »

Twitter good
Posted by: Alex Miller on 05/09/2008

Alex Miller
Just saw this post about reasons people Twitter. After having been on Twitter for 2 weeks I completely disagree with all of these except maybe weakly on #4 - I don’t use it for any of those reasons. So far the benefits I’ve seen from using Twitter: News - I see links and news of interest to me faster than I do via blogs and feeds. Twitter is an amplifier. If the people you follow share your interests, anything popping from there is far more likely to be interesting... more »

Integrating Spring and JBoss SAR Components
Posted by: Vladimir Vivien on 05/08/2008

Vladimir Vivien
Integrating Spring and JBoss SAR Components Last time I wrote about JBoss, it was a discussion on how to create a JBoss service component (SAR). However, in many cases, a SAR component has to be integrated with other component-based technologies. In this article, I will discuss how to accomplish this by integrating the JBoss with the Spring component model and how to expose Spring components to receive management services from within JBoss JMX Console. Integration ... more »

SOA: Time For a Rethink
Posted by: Michael Nygard on 05/08/2008

Michael Nygard
The notion of a service-oriented architecture is real, and it can deliver. The term "SOA", however, has been entirely hijacked by a band of dangerous Taj Mahal architects. They seem innocuous, it part because they'll lull you to sleep with endless protocol diagrams. Behind the soporific technology discussion lies a grave threat to your business. "SOA" has come to mean top-down, up-front, strong-governance, all-or-nothing process (moving at glacial speed) implemented by... more »

The JVM is Great, But...
Posted by: Michael Nygard on 05/08/2008

Michael Nygard
Much of the interest in dynamic languages like Groovy, JRuby, and Scala comes from running on the JVM. That lets them leverage the tremendous R&D that's gone into JVM performance and stability. It also opens up the universe of Java libraries and frameworks. And yet, much of my work deals with the 80% of cost that comes after the development project is done. I deal with the rest of the software's lifetime. The end of development is the beginning of the software's life. Throughout... more »

JavaOne: Geert Bevin on Java as API
Posted by: Alex Miller on 05/08/2008

Alex Miller
Actually Geert’s talk was called “Boldly Go Where Java Has Never Gone Before” but to me it was really centered on the idea of Java-the-language as interface. You can really divide the Java platform up between two specifications - the language spec and the VM spec. Above the language spec you have Java source. Between the two you have byte code and below the VM spec you have runtimes. Everyone is quite familiar with the fact that other languages can be compiled to... more »

JavaOne: Cliff Click on Data Races
Posted by: Alex Miller on 05/08/2008

Alex Miller
Cliff’s talk focused on what data races are, why they happen, and how to debug them. A data race occurs when you have at least two threads accessing the same data and at least one of them is writing, and there is no ordering defined based on the Java memory model (by using synchronization, volatiles, Locks, etc). In this case, instruction reorderings can occur either in the hostpot JIT or in the hardware itself that will give you surprising results. In fixing data races, a key... more »

JavaOne - OSGi Is Huge Here!
Posted by: Vladimir Vivien on 05/08/2008

Vladimir Vivien
If you doubted that OSGi can achieve mass appeal, the list of sessions at J1 proves contrary. Most major tool vendors has either implemented it or have plans to support OSGi bundles:OSGi has been in IBM's arsenal for while now (Eclipse, Websphere, etc)SpringSource's new Spring Application Platform uses OSGi has its Glassfish Version 3 will be OSGi-bundle compatibleJBoss 5's kernel will load its component as OSGiJSR 277, the Java Module system, slated for JDK7, can load OSGi bundlesFrom... more »

Me at JavaOne: Design Patterns Reconsidered
Posted by: Alex Miller on 05/08/2008

Alex Miller
Speaking of talks, I will be presenting at JavaOne today (4:10 pm in Gateway 102/103) on “Design Patterns Reconsidered”. I’m about 80% excited and 20% terrified, which is a good mix for me. I’ve given this one in different forms a couple times and I know this will definitely be the best version of it I’ve ever done. If you’re interested in design patterns, stop on by. Session abstract: The design patterns movement launched a revolution in... more »

Guice talk at St. Louis JUG

JavaOne: Bachorik and Sporar on Application Monitoring Tools
Posted by: Alex Miller on 05/07/2008

Alex Miller
This talk was from a couple Sun guys and looked at a bunch of tools that are available for performance monitoring and debugging. The tools they talked about were: dtrace - dynamic fine-grained instrumentation tracing, works kernel all the way up Sun Studio collector/analyzer - some tools that give good visualization, are based on sampling and have good Java integration jps, jinfo, jstack - part of the JDK, allow you to get info on running Java processes, vm properties and args,... more »

JavaOne: Neal Gafter on Closures
Posted by: Alex Miller on 05/07/2008

Alex Miller
I was excited to see Neal talk about closures and I think he did a pretty good job staying focused on practical ways to use closures to reduce boilerplate. The problem with talking about closures is that it’s hard to stay focused on the practical benefits without getting bogged down into debates over syntax and features. On that front, I think Neal’s talk was a big success. The initial part of the talk did a pretty quick ramp up on what closures are and where you might use... more »

JavaOne: Eugene Kuleshov, Misko Hevery on practical byte code
Posted by: Alex Miller on 05/07/2008

Alex Miller
This BOF was “Practical applications of static bytecode based analysis”. Eugene did the first half of the presentation and went over the basic capabilities of ASM. ASM is a great library for doing bytecode generation, transformation, and analysis. We use ASM a lot at Terracotta so this was mostly review for me but it did fill in a couple questions for me. Eugene also covered Cobertura, which is a code coverage tool that uses ASM to instrument counters around every method,... more »

JavaOne - Service Component Architecture and Tuscany
Posted by: Mike Levin on 05/07/2008

Mike Levin
" title=""Open Source Service-Oriented Architecture with Service Component Architecture and Apache TuscanyThis is a component based programming model that abstracts away the complexity of the underlying components and leaves you to concentrate on the business logic. From my perspective, it's a clean way to reuse components and I plan to look into it more. The demo was flawless and explained how an online store was implemented also using json-RPC and then enhanced to include another catalog.... more »

SAP's SOA ESR
Posted by: Michael Nygard on 05/07/2008

Michael Nygard
SAP has been talking up their suite of SOA tools. The names all run together a bit, since they each contain some permutation of "enterprise" and "builder", but it's a very impressive set of tools.Everything SAP does comes off of an enterprise service repository (ESR). This includes a UDDI registry, and it supports service discovery and lookup. Development tools allow developers to search and discover services through their "ES Workspace". Interestingly, this... more »

JavaOne - Detachable Applets
Posted by: Mike Levin on 05/07/2008

Mike Levin
One of the demos at JavaOne is billed as the "Return of the Applet." Detachable applets can live outside the browser. This is a cool technology. Basically, you can drag an applet from your browser onto your desktop and leave it there, even after the browser is closed. This reminds me of widgets and gadgets. It's yet another move in a web-centric direction. You can catch a lot of the info including the general sessions as webcasts at http://java.sun.com/javaone more »

Type Inference Without Gagging
Posted by: Michael Nygard on 05/07/2008

Michael Nygard
I am not a language designer, nor a researcher in type systems. My concerns are purely pragmatic. I want usable languages, ones where doing the easy thing also happens to be doing the right thing. Even today, I see a lot of code that handles exceptions poorly (whether checked or unchecked!). Even after 13 years and some trillion words of books, most Java developers barely understand when to synchronize code. (And, by the way, I now believe that there's only one book on concurrency you... more »

Improvements to the Tapestry 5 Tutorial
Posted by: Howard Lewis Ship on 05/07/2008

Howard Lewis Ship
I spent some time yesterday revamping the Tapestry 5 Tutorial; you can see the updates at the nightly build site. In short order we turned the Address object into a Hibernate entity, and stored it in a MySQL database, then used a Grid to show the added Addresses. Later improvements to the Tutorial will show editting and removal of Addresses. I think the correct reaction to this would be "Dude, where's my code?". The application code for this app is so small you'd... more »
