Ok. How many applications use eRCP/eSWT at the moment?

Not many I think, not so many phones support eRCP yet.
No phone from Nokia support eRCP, but eSWT is supported in all Nokia S60 phones from version 3.2.

MIDP 3.0 is in Proposed Final Draft, so there is no JavaME VM with support yet. Read more here: http://jcp.org/aboutJava/communitypr...271/index.html

Is the guy who has made this statement working for Nokia?

yes, i think this is a nokia employee. his picture, title and activity suggest that.

Who, other then SUN, even needs JavaFX? Are there any useful JavaFX applications? Will there ever be any? As far as I can tell, the world seems to have standardized on Flash for these purposes.

I have not said "no" to JavaME. In fact, I continue insisting that we absolutely need JavaME on Maemo, because there are so many applications written in JavaME on the market.

As of now, more interesting is compatibility layer for Android, or even iPhone OS. I don't mean to run complete Android OS, but to run an application which is unique to Android without replacement/alternative/port on Maemo.

very interesting, didn't know about that!

i will add it to the Java SE Proposal:


community or nokia builds Iced Tea
+) true GPL, no binary components
-) no team so far
-) no official advertising

Unfortunately a lot of people, like you, think that there is a jvm in the Android platform. The vm used in Android is called Dalvik and it is not a jvm. The only thing Java about Android is the syntax and the syntax has little to do with performance. Thus your example has no relevance in the Java discussion.

The most important thing lacking in the Dalvik VM is a JIT. The difference in speed has been measured to 5-10 times faster with the JIT. The actual speed naturally depends on what you do but a better figure to use is that Java runs at about 80% of the speed of native programs.

If you had read all of my post you would have noticed that I see the need for some programs and parts of programs that run on the native platform.

However most applications are not image filtering and why would you want to to manage the memory of simple data lookup and entering app?

I think we have all see all those great C developers that "know" how handle memory of apps the leak memory, forcing us to restart the app regularly. A large number of security holes are due to developer that cannot handle a simple buffer overflow. I guess we have to expect a huge increase in mobile worms in the future.

Then, personally, I do not see any reason to support these. The only reason to support any kind of Java is to get access to existing library of applications.

Fine, you don't use Java or Java apps. Yes, we get that. In that case, the provision of a Java SE or Java ME layer will have zero impact on your usage of the device.

I can't think of any Ruby based apps off of the top of my head

Cons :
* A few megs of storage space is used - you could spend a few minutes writing a shell script to delete all the Java stuff if you were that bothered,

JavaSE would indeed be what Blackboard runs. It has a forum system - I never worked out why it needed to be java. I can't reply to anything from an NHS computer because the java on those is out of date (they run XP with IE6 and regular staff don't have admin access to update.) I was under the impression that n900 could handly that sort of java? Did I not see it running a chat applet in one of the videos? (Or did I dream that bit?)
