JavaOne is once again organized in San Francisco next week (May 8-11). Nokia will have a booth in the expo floor and we will be demoing various Java technologies in there (as well as during  a number of mobile Java talks by Nokia personnel). I'll be there, can I expect to meet there anyone from here?

A couple of sessions in the conference (generic schedule here) I am looking forward to:

• The six-month report on OpenJDK progress, including activities in the mobile and embedded communities by Terrence Barr during the CommunityOne day on Monday as well as the NetBeans 6.0 and Mobility presentations in the same event.
• Tackling the Java fragmentation by Nir Vazana on Tuesday.
• How to Work with Java ME Carriers by Nathan Smith, also on Tuesday
• Building Java ME test suite in 15 minutes on Wednesday
• JRuby on Java ME on Thursday
• Speech events and recognition on devices on Friday

Nokia announced seven entry-level phones today. Java applications can installed on three of those seven phones. The model numbers of those Series 40 phones are 2630, 2660 and 2760. 

The set of Java APIs on those low-end phones differ a little from the mainstream Series 40 devices as there are fewer supported APIs on those devices than for example on Series 40 3rd Edition FP2 devices, but there are also some APIs supported, which are not available on Series 40 2nd or even 3rd Edition devices.

For example there is no Mobile 3D Graphics API (JSR-184 or SVG API (JSR-226) on these newly announced devices. On the other hand the APDU package of SATSA API (JSR-177) is supported.

So when targeting these phones, make sure you are not trying to use an API which is not available. Also note that because of limited available memory, the max JAR size is only 256 KB and heap size for those apps is 512 KB.
