It’s been a while… for the Amsterdam Java Meetup that is. I’ve been traveling a lot and haven’t been able to organize another meetup past quarter. But here we go again: the (almost) quarterly Amsterdam Java Meetup with free drinks (or at least, the first few rounds) will be hosted in grand-cafe de Jaren in Amsterdam (see below for more info on the location) on the 23rd of May. You can expect many Java devs (usually between 50 and 80 people turn up), technical as well as non-technical discussions and of course, the latest gossip in the Dutch Java industry. We’d love to hear from people from ‘the other side’ (other other sides, I should say) as well, so if you’re doing Ruby or .NET, don’t hesitate to join in too!!
It has been a busy few months since SpringSource partnered with Hyperic to bring our Application Management Suite (AMS) product to market. I am pleased to announce that the SpringSource AMS beta release is now available to all. Please take a moment to evaluate the software and post your thoughts on the beta forum. We are committed to providing the best application management experience possible for Spring-powered applications, and your feedback is much appreciated!
Those who expressed an interest in SpringSource AMS at The Spring Experience in December received an email announcing the beta release. Here is an excerpt from that email that introduces SpringSource AMS and outlines some of its additional features:
After being in the works for about six months, I’m happy to announce that Spring Web Services 1.5.0 has been released! In this post, I’d like to go over some of the major new features.
The 1.5 release includes two new transports: JMS and email. Using these new transports requires no Java code changes: just add a bit of configuration, and you’re off! The JMS transport integrates nicely with Spring 2’s Message-Driven POJO model, as indicated by the following piece of configuration taken from the airline sample application:
Today I am delivering a presentation entitled Spring for Java Server Faces at TSSJS in Las Vegas. The presentation looks at how JSF and Spring fit together, and walks the audience through approaches to integrating these two technologies.
The slides are available for your viewing pleasure, and for you to use as you see fit.
In the presentation, I outline two approaches to integrating JSF and Spring. The first approach is what I call “JSF-centric”, which is the integration approach most folks with a traditional JSF background employ today. The second approach is what I call “Spring-centric”, which is a new, groundbreaking approach to JSF integration driven by the work done in the Web Flow 2 distribution.
Today marks the third milestone release of the Spring Java Configuration project (JavaConfig for short). The release contains numerous bug fixes and new features - I’ll highlight a few of the most interesting changes below, but first let me give a quick refresher as to what JavaConfig is all about.
If you have any experience with Spring, the following snippet of XML configuration will likely be familiar. Let’s assume we’re looking at a file named application-config.xml:
<beans> <bean id="orderService" class="com.acme.OrderService"/> <constructor-arg ref="orderRepository"/> </bean> <bean id="orderRepository" class="com.acme.OrderRepository"/> <constructor-arg ref="dataSource"/> </bean> </beans>
In Spring 2.5 it is possible to use annotations to configure all parts of a web application. Seeing annotations applied is particularly interesting in the Web layer where developers traditionally rely on the SimpleFormController and the MultiActionController for form page handling. The introduction of annotations has created a third option, one that does not require a base class while still offering the flexibility of previous approaches.
While it is easy to see the elegance in using annotated POJOs to implement Controllers, the benefit is not as clear in the area of URL-to-Controller mappings. What would it be like to define all your URL mapping rules using annotations? Indeed this is one area in which centralized configuration has worked well for developers of Spring MVC applications.
This year's EclipseCon was the first that we attended as a company. We had quite a few talks, which were all well received and we announced the beta program for SpringSource Tool Suite. Overall we all had a very great time and we got lots of feedback from the Eclipse community about the projects in the Spring Portfolio and especially what we are doing in the web space. I'll make sure to forward all the feedback to the project leads in the coming weeks. Since EclipseCon is coming to its end today, I finally found time to sit down and write about what we introduced at the conference.
I’m writing this as I’m on my way to Cairo. We’re flying just West of Italy and I have clear view on the Italian coast line, with its blue waters and waves gently moving towards shore. It must be nice down there now. I’m heading to Cairo for a meeting of the Egyptian User Group, organized by Ahmed Hashim, who no doubt will have done an excellent job, I’m sure of that. I’ll be presenting on Spring with the theme this time being Dependency Injection, type safety and Java 5. Yesterday (March 14th that is), I did almost the same presentation at the Profict Wintercamp in Loenen, NL for an audience of 60 of 70 I think.
The Web Flow team has been working hard on Web Flow 2. We just reached our 4th milestone and will enter release candidate status as early as next week. The 2.0 final release is scheduled for the end of the month.
Between now and 2.0 final, we’d like your feedback! If you are an application developer currently using Web Flow 1.x, or evaluating Web Flow for use in your project, please give 2.0 M4 an evaluation and let us know what you think. If you are a web framework provider integrating the Web Flow engine into your framework, we encourage you to evaluate the refined hooks in 2.0 M4 and give us a shout out.
I’ve allways been a fan of test driven development, and to my disappointment at first sight it looked like TDD and GWT were not going to play together.
