It is now possible to configure Spring’s dependency injection with annotations. This means that annotations can be used in Spring to mark fields, methods and classes that need dependency injection. Spring also supports auto-wiring of the bean dependencie. Annotations can also be used to indicate fields that are to be auto-wired. Furthermore, auto-detection of annotated components in the classpath is also supported now. When these capabilities are combined, the amount of configuration and dependency mapping in the Spring configuration files is reduced drastically.

Spring could be an alternative to expose Mbeans (see Spring doc).
The JMX support in Spring provides you with the features to easily and transparently integrate Spring application into a JMX infrastructure.

Specifically, Spring’s JMX support provides four core features:

• The automatic registration of any Spring bean as a JMX MBean
• A flexible mechanism for controlling the management interface of your beans
• The declarative exposure of MBeans over remote, JSR-160 connectors
• The simple proxying of both local and remote MBean resources

Wednesday December 12th, I went to the Javapolis 2007 edition. After some troubles finding the right tram to go to the right place, I finally catch… the right bus! Arriving at the entrance, I met a colleague of mine, that had a very bad news: “they don’t know us!”. After some phone calls, we ended up to find our two badges in a partner stand. (We will have to thanks our boss!)

No time for food, James Gosling’s speech, “The state of the java universe”, will begin in a few. Three rooms totally full listened to James attentively. We had news about Java, Java Fx andNetbeans + a cool demo with 2 funny robots.

The second conference, I saw was the new SoapUI presentation by Ole Matzura. As a developer, I did not find it very useful but it seems to be really a nice tool for testers.

Time to eat now! I met a colleague of mine wandering for his accreditation After getting it, we began the endless queue to get our lunch disappointing hot dogs. Really, that did not do it!
After this, we went to see the Google web toolkit presentation by Dick Wall. A tool that lets you build AJAX applications by converting Java class into javascript. Very interesting, but the demo was a little bit confused.

The next conference I saw was the “SOA Development using JBossESB” by MarkLittle. His presentation was very clear! He explained the place of SOA and ESB (two buzzwords of choice today…) in the development process an their places in the WS-* architecture.

The last conference I saw was “JSR 318 - Enterprise JavaBeans 3.1″ by Kenneth Saks. Too tired, I had to leave at the half of the presentation. (I had still to catch a bus and two trains to come back home…).

Finally what I liked:

• the quality of the conferences I saw
• the whiteboards concept

… and what I didn’t like:

• the lunch queue
• the lunch
• the commercial (but normal) part (stands)
