Transferred to Spring this means that the Spring…

'Long time no blogging... Die letzten Tage war ich auf der JAX Konferenz in Wiesbaden.  Am Dienstag hatte ich dort eine sehr gut besuchte Session zum Thema "Advanced GlassFish". In der Session habe ich ein paar weiterführende Themen wie Monitoring, Comet, OpenSSO und Scripting mit GlassFish diskutiert. Für Interessierte - hier ist der Link auf die Praesentation. Heute läuft dort die Keynote unseres neuen Kollegen Dalibor Topic zum Thema OpenJDK. Blogged with the Flock Browser'…

' For the past year I've been doing some major Open Source strategy consulting for a global BigCo. It has been (and still is) a fascinating and extremely fulfilling experience. My focus hasn't been on implementing a software project but on authoring an internal Open Source strategy whitepaper and establishing things like an Open Source policy and Open Source guidance or setting up an Open Source internal community within said BigCo. Seeing the growing interest for Open Source within the…

'Switching regularly between .NET and Java definitely does not facilitate remembering the details of one platform or the other. For me, however, it made me see how similar both platforms are and consider C# to be a (slightly) improved version of Java. For the most part, I still think that´s true. Explicit properties, delegates and events make coding certain programming idioms somewhat smoother and more readable than using bean conventions and anonymous inner classes. That said, I still shy...'…

• Download GlassFish V2 beta2 (eg build 41c) from here
• Execute java -jar glassfish-installer-v2-.jar

' It is important to remember, that IActionBars instance is shared between all instances of editors of same type. It means, for example, that if you will call setGlobalActionHandler() form editor's createPartControl() method (as i did today) - every new editor instance will overwrite global action handler. Usually, it is not what what you really want. For creating actions, that are shared by different instance of of same editor - org.eclipse.ui.editors.IEditorActionBarContributor should be used. '…

' Some of you may not have caught up with InfoQ yet :- it's a great site for community news and articles concerning enterprise development (it's not restricted to just Java: I like seeing ideas from other communities too).

' Update: the JRockit team gave outstanding service on this issue, and found and fixed the bug in their VM within 24 hours of it being reported. The code generated by AspectJ has also been tweaked so that it does not trigger the bug on VMs that do not have the patch. We had a bug reported on the aspectj mailing list this week, in which a simple program returning a boolean value would return "true" when the code clearly…

' For the past 2 months I've been working extremely hard putting together a course on AOP with AspectJ and Spring 2.0. One thing I've learnt is just how much effort goes into such a venture: each teaching module, with it's associated hands-on labs, samples, and presentation material takes between 1.5 - 2 days to prepare, and there are four modules on each day of the course. However hard I tried, I couldn't develop the material any faster than that.…

' Graham Hamilton posted a blog entry on AOP this week. It's attracted a good deal of criticism in the responding comments - probably because of the provocative writing style. Graham's certainly been in the game long enough to know the difference between technical discussion and political positioning - and how to blur the two. Graham divides his criticism into "the good", "the bad" and "the new". "The good" includes container based AOP, "the bad" includes just about everything else.…

' In Germany they have an entire magazine devoted to Eclipse, called (imaginatively ;) "Eclipse Magazin"". I don't speak (or read) German, but I have to say the content always looks really good, and they've had some excellent coverage of AspectJ and AJDT in past issues. The magazine has a guest column, "MyEclipse" in which various users of Eclipse describe their favourite hints and tips for working with the IDE. It was my turn to write the column this month.…

' This entry represents part one of a two-part guide to using an aspect library (with AspectJ). I wrote it in December of last year, and have been waiting to finish part II before publishing it.

So with no further ado: Introduction With the arrival of AspectJ 5 and the Spring 2.0 milestone builds, many of you…

' One of the things I like to do when I visit a client is to take a look at the books on their bookshelf (and those of the other members of their team). I do this for three reasons.

Secondly, it tells me a lot about the background and…

' I spent a few days last week working on argument binding in advice for the new aop schema and @AspectJ support in Spring 2.0. In this article, I'll explain how the new support works and how you can use it. First some background for those of you who haven't been following along with developments in Spring 2.0. Spring 2.0 supports schema-based configuration as well as DTD based. Schema gives better validation, a better experience in the IDE (in terms…

• AspectJ - 7,400
• AJDT - 20,000

' Long overdue, but I've finally repackaged all of the examples from the Eclipse AspectJ book for easy installation on Eclipse 3.1 and the latest AJDT. Here's the download link and installation instructions. Since the book was published, AJDT has introduced the Cross References View. If you are following along with the text, relationship information (such as "advises" and "advised by") is now shown in the Cross References View and not in the outline view. To run the junit tests…
