Maximiliano Firtman's Forum Nokia Blog - The Future of Java ME II

This comment may be off topic but I have not been able to find the answer anywhere else.

Does Nokia support awt.Robot in its CDC platform?

We have a gui/unit testing tool that is device independent (i.e does not rely on capture-and-replay or Windows) that can run in CDC devices.

Thanks a lot in advance!!!

That's right, there isn't CDC/PP phones yet. It's also right that MIDP 1.0 / CLDC 1.0 is still alive. In some worldwide regions, like Latin America, there is still a big MIDP 1 market, like Nokia Serie 40 First Edition. And there are yet TDMA Java-less phones!. This is changing, because people with older phones, are looking for new color devices with camera or MP3 player. In 12 or 18 months, a great percentage of people are changing their mobile phones to a newer generation.

Today we don't have CDC phones, what will happen in two/three years? It's like Flash Lite platform, we don't have enough flash enabled devices right now. That means that we don't need to analyze and start to work in this platform? I don't think so. Time runs too fast...

"But it is different for JavaME/CDC/PP, I think JavaME/CDC has not yet hit its mark with smartphones and PDAs.
For JavaME/CDC/PP there are nearly no devices you can buy, for example how many Nokia devices have support for JavaME/CDC1.0/PP1.0? , not many phone and for JavaME/CDC1.1/PP1.1 there is no phone"

Hello,

Mr.Ove Nordström,

All Nokia Phones' Support's MIDP1.0/CLDC1.0 .

Vinny.

Hi,
I am not sure if devices like Nokia 770 and UMPC (Microsoft's Ultra Mobile PC) will run well if they only have support for JavaSE. I think JavaME/CDC1.1/PP1.1 is perfect for these small devices. The next problem is which company can supply a JVM for these devices? The PocketPC platform is a good example how difficult it has been to find a JVM for that kind of device.
Perhaps now when SUN Open Source JavaME it will help us?

I agree that JavaME/CLDC/MIDP is already available on many consumer cell phones.
No hardware problem here, only Java fragmentation problem
So I agree MSA for CLDC (JSR-248) is something really good for us developers!
I look forward when we have devices that support JSR-248 (MSA for CLDC) and JSR-249 (MSA for CDC). But again there are no devices that support it yet!
We will have devices soon that support JSR-248, but for JSR-249 it will takes some time I believe, I hope it will be a faster process to agree about this JSR-249!

But it is different for JavaME/CDC/PP, I think JavaME/CDC has not yet hit its mark with smartphones and PDAs.
For JavaME/CDC/PP there are nearly no devices you can buy, for example how many Nokia devices have support for JavaME/CDC1.0/PP1.0? , not many phone and for JavaME/CDC1.1/PP1.1 there is no phone.

I also think that the JavaME/CDC1.0/PP1.0 implementation has not been so well so far.
You can often find frustrated developer telling you:
Why are CDC implementations always so buggy, read more here:

But I think there will be a change during 2007, with more devices supporting JavaME/CDC1.1. But it look like the next generation GUI on wireless handsets is not settled yet (AGU or eSWT), read more here:
http://ovenordstrom.blogspot.com/2006/09/aguijsr-209-is-finished-but-dont.html

Because of that I think we will have devices during 2007 supporting Java ME/CDC1.1/FP 1.1 profile with eSWT and other devices supporting Java ME/CDC1.1/Personal Profile 1.1 with AGUI (like the SavaJe phone) and Java fragmentation problem again for the JavaME/CDC platform.

Hi Ove, thanks for the link. I've read your post and I'm a bit confused about what you meant. Devices like Nokia 770 and UMPC (Microsoft's Ultra Mobile PC) are Internet Tablets or Mini Tablet PCs. That devices are using "desktop-like" operating systems, as Linux (in Nokia 770) and Windows XP / Vista in UMPC. So, Java SE wins the place in Java development for that devices. You can install a Java SE Virtual Machine. Personal Profile for Java ME is in the middle.

And I don't agree with your opinion that we already had a lot of APIs. Until last year, for example, we've only had devices with JTWI (Java Technology for the Wireless Industry) and some other APIs installed. But there was a lack of features we can use from Java ME. Now, with this new APIs to become a new "big standard" as MSA (Mobile Service Architecture), we'll have less fragmentation. And we need more... for example, we need to make background Java applications and now, we can't do this.

The lack of features in Java ME isn't a hardware problem. The hardware is there, sometimes we can't access it from Java APIs. A great example is the first version of Motorola RAZR v3... it has bluetooth, but it doesn't have the Bluetooth API !. Is it a hardware-lack problem?

For some API, like Location API, yes... we need more devices with some hardware, like a GPS.

Hi,
I wrote little about this in my blog: http://ovenordstrom.blogspot.com/2006/10/future-of-javame-is-also-about-new.html
