Runtime Error Analysis in the SpringSource Tool Suite

Engineering | Alef Arendsen | April 14, 2008 | ...

Three weeks ago, the SpringSource Tool Suite was released. Christian, in charge of this product blogged about it already and we also have a webinar available for those of you that want to get up to speed with all of the functionality it currently offers. In this entry, I wanted to highlight the runtime error reporting functionality specifically.

When I'm programming, sometimes, the console window shows dozens of stack traces due to some error I've caused. Sometimes, I'm lucky and the stack trace looks familiar. If so, then the problem is probably easy to solve. Sometimes however, the…

The Biggest Loser's Next Contestant: Java Bloatware

Engineering | Rod Johnson | April 09, 2008 | ...

If the tech community were to host their own version of the popular TV show The Biggest Loser (or maybe Celebrity Fit Club) you would see enterprise Java front and center---bloated, overweight, tired, and drained.

The future of enterprise Java is becoming clear. The morbidly obese legacy platforms are in decline, with leaner solutions increasingly used in production as well as in development. Legacy technologies such as EJB are becoming less and less relevant.The lukewarm takeup of Java EE 5 leaves it looking increasingly like the last gasp of traditional J2EE bloatware. Meanwhile, the Java EE 6 specification is finally set to allow for greater modularity, in a radical change which will have important implications for developers and is likely to rejuvenate competition among implementations. As the standards and the products based upon them have gathered pound after pound of cellulite, SOA, Web 2.0 and other infrastructural changes continually impose new requirements that were not foreseen…

Q2 Amsterdam Java Meetup - May 23rd 2008

Engineering | Alef Arendsen | April 08, 2008 | ...

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…

What's New in Spring Web Services 1.5?

Engineering | Arjen Poutsma | March 28, 2008 | ...

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.

New Transports

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:

<jms:listener-container connection-factory="connectionFactory">

Spring For JavaServerFaces - TSSJS Slides and Demos

Engineering | Keith Donald | March 27, 2008 | ...

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…

Spring Java Configuration - What's New in M3

Engineering | Chris Beams | March 26, 2008 | ...

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:

	<bean id="orderService" class="com.acme.OrderService"/>
		<constructor-arg ref="orderRepository"/>

Using a Hybrid Annotations & XML Approach for Request Mapping in Spring MVC

Engineering | Rossen Stoyanchev | March 23, 2008 | ...

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…

SpringSource Tool Suite Released

Engineering | Christian Dupuis | March 20, 2008 | ...

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.

We unveiled the Personal Use Edition of SpringSource Tool Suite (STS) during our BoF on Monday and I have spent a lot of time talking and mailing to people about what extra value it brings. In this blog I will outline the features of the SpringSource Tool Suite in more detail. First of all, I have heard quite a few times that people think that the announcement of the SpringSource Tool Suite means that we will stop improving and shaping Spring IDE. Please let me make the point that this absolutely not the case; actually the opposite is true and already evident by taking a look at the Spring IDE JIRA and Subversion repository. In fact since I joined SpringSource in January, I was able to increase the amount of time that I spent on Spring IDE while working on the tool suite in parallel.

The goal of the SpringSource Tool Suite is to give you the most sophisticated development tools for doing enterprise development with the Spring Portfolio on the Eclipse platform - sounds like marketing slang but that is the mission statement the tools team is committed to. STS certainly builds on top of the proven Spring IDE but it ties deeply into Eclipse Mylyn and already extends both open source tools to bring enterprise level extensions into your IDE. With the effort to provide the best Spring tooling available we already started and continue to add tooling related features, hooks and extension points into the Spring core framework and other Spring projects.

So with the tool suite you finally get all the benefits of Mylyn's Task-Focused User Interface for doing Spring development. You get context management and focusing while working on Spring application blueprints. Additionally we took the Task-Focused UI approach to a new level and introduced a new technology that we named Task-Focused Tutorials. Task-Focused Tutorials extend the Eclipse Cheat Sheet framework and add task-focusing to each step of the tutorial. With a Task-Focused Tutorial a user - someone new to Spring or someone who wants to learn a certain feature or Spring project - will be able to import a running sample application with a single click and start exploring the sample. Each tutorial step will then provide an explanation of a certain aspect of the tutorial and show only those Java and Spring elements that are relevant to understand and explore the explanation.

Task-Focused Tutorials

From the above screenshot you can see how that looks in Eclipse. The tutorial brought the PetClinic sample application into the Eclipse workspace and focused the workspace to show only the @Autowired annotation and how it is applied to application components. On the right side you can see the expanded step that explains how and why you should use the @Autowired annotation. At the very end of the tutorial the user is able to launch the sample application on a bundled Tomcat server that is automatically installed and configured; again just with a single click.

We think that this way of introducing new features and products is a very powerful approach and makes it really easy for people to explore the Spring Portfolio. Everything a developer needs to have and know when getting started is right where it should be: inside the IDE. When you download the Personal Use Edition Beta you will have instant access to around 20 tutorials that have all been created by either project leads or experienced consultants that directly work with clients. Most notable Adrian Colyer took time to create 7 tutorials that introduce OSGi concepts, Equinox and Spring Dynamic Modules. These tutorials are really cool if you want to jump on the OSGi train right now. The tool suite contains a automatic OSGi bundle update/refresh mechanism that finally allows working on applications and get instant redeploy semantics based on the power of the OSGi runtime (have you ever tried that with EJBs; I did).

The next feature I would like to talk about is called Runtime Error Analysis: the SpringSource Tool Suite is able to provide information on how to solve runtime problems by analyzing Java stack traces. To make that happen we created a online knowledge base that is integrated into the suite and which is being queried right inside the Eclipse IDE. The knowledge base is open for everybody using the tool and we even encourage people to contribute their own analyses by using build-in rich editing features. Take a look at the following screenshot.

Runtime Error Analysis

With the tool suite you don't only get support for analyzing runtime errors but also the tool will help to find common pitfalls and Spring best-practice violations. Especially while working on XML bean definition files this feature becomes really handy as it will inform the developer right inside the XML editor that there is something in the file that he/she might want to revise. For example the tool will detect and recommend the usage of bean inheritance under certain circumstances. Also it will recommend the usage of the constantly improving namespace elements instead of using traditional style bean definitions. Here is an example:

Runtime Error Analysis

So lets see what we got:

  • Spring Development Tools
  • Mylyn's Task-Focused User Interface for Java, Resources and Spring application blueprints
  • Task-Focused Tutorials
  • Runtime Error Analysis
  • Best Practice and Architecture Review tools

There are more features that I haven't touched on. Do you see the main theme in this feature line-up? The last three listed features provide invaluable assistance to develop powerful Spring-based applications. Internally we started to use a metaphor for that feature set: Consultant in a Box. With the SpringSource Tool Suite we want to give access to SpringSource knowledge as if you had a consultant sitting next to you!

I would like to encourage everybody to head over to the beta registration page and give the Tool Suite a try. In closing I also want to say thanks to everybody who has already submitted feedback, issues and suggestions. I will get back to all of you as soon as this overwhelming week at EclipseCon has ended.

Spring Dependency Injection & Java 5 (including slides and code)

Engineering | Alef Arendsen | March 18, 2008 | ...

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…
