I recently got a new mobile phone, a Nokia 6310i, with support for J2ME. So now i’m trying to find out how J2ME works and how usefull it is. Sofar,i’ve got my own HelloWorld MIDlet running…
Some usefull documents to get started with J2ME: – J2ME datasheet – MIDP datasheet – Bill Day’s wireless 101 – Nokia developers forum – Using Ant and Antenna to Build MIDP Applications v1.0 (From nokia forum)
Yesterday I attended the ONEday seminar organized by Sun in Rotterdam, the Netherlands. This one day seminar consisted of two parts, a more management focussed part and the Sun Developer Day, focussed on Java Developers. Basically, it’s the JavaOne, compressed into 1 day. And this showed in all the presentations. Too many subjects, not enough depth. The one thing you could learn here is what Sun wants you to focus on, not how it works. The best presentation was one about changes to the garbage collector in j2se 1.4.2. The last presentation, about the Sun ONE application server was a bit of a joke, as the presenter was just reading the titles of his slides,without adding anything of interest.
Anyway, a more complete summary of this day in dutch can be found here.
Now, i’m not sure these days what OSS stands for, is open source software or open source soap?
We can all start to write very dramatic blog entries. But i’m not afraid for the future of jboss or it’s use within companies. Both the JBoss group and JBoss Core Developers depend on a successful jboss product. Even if they can’t cooperate on the product, it’s not the end of the world. The code base will be forked, and one will become the leading jboss implementation.
Denim seems like a nice tool to use when investigating the requirements for a new website. Especially during an interactive session with the client in the room. I already have a graphire pad, finally something that makes it usefull…
In the inquirer: JBoss 4 and AOP, what gives with it?.
Too often people accuse open source projects of not being innovative and only re-implementing existing standards and software. It’s good to see that the JBoss people are trying to innovate in an area where it’s very much needed, J2EE is too complex, and if JBoss’ use of AOP can simplify this, i’m all for it. Try it, discuss it, and hopefully if we all agree that it’s a good thing then at some point in the future it will end up in the J2EE standards.
Another update of the volano is available. It’s always interesting to see which JVM is the fastest and which one is the most scalable. Hopefully next time, they’ll also include the OS X jvm.
Now that JBoss 4 is about to be released, discussions about JBoss’ j2EE certification are also popping up again (here, here).
For me, it doesn’t really matter whether JBoss is certified or not. When I design and write Java applications I will follow the J2EE specifications. Hopefully whatever I do will work in JBoss, and if it doesn’t I’ll complain, file a bug report and create a workaround, as I do everytime I find a problem with some software I have to use. But I’ll stick to the standards, as this will allow me to write portable applications.
As it stands now, JBoss complies enough with the J2EE standard that it can be used in projects. The JBoss project would only hurt itself by not prividing all the standards, as developers would look elsewhere for a better application server.
