Next Generation UMPC (Origami devices) is called 'Vistagami' tablets
Interesting things about Vistagami:
- Hopefully, Lower prices, $500 is the price goal
- Vistagami devices will run Windows Vista, rather than XP
- As for Vistagami, Microsoft is still aiming to have devices ready by the time Vista ships early next year (January 2007).
I hope they are also able to fix the lack of all-day battery life, it is critical I believe!

what I would have to next JavaOne
I am tired of bring my laptop pc to JavaOne, to heavy and the battery time is only 3 h.
I need something else so please Nokia (or any other company) fix it to next JavaOne, a handheld device with a keyboard like the UMPC!
My Windows XP installation crash 05.00 pm the day before departure to JavaOne, I had to reinstall my laptop pc, I finish the installation 11.30 pm and 03.30 I went up to go to JavaOne
Continue report from the NetBeans Software and JavaOne2006 conference in San Francisco
I join the NetBeans Software Day at the 2006 JavaOne Conference and JavaOne conference.
Some more interesting things from those events:
- The JavaOne conference of course had lot of session about Java EE 5.0 that was finishing some days before the conference. It is funny it was not a big happing during JavaOne that they released this huge improved version of Java EE. I think it was because developers have waiting so long for this release and most of us know a lot about this release already. Anyway I went for some EJB 3 sessions and I must say it look really nice, include in EJB 3.0 is also a new Java Persistence API (JPA). There was not so much talk about Hibernate, look to me EJB 3.0 have been accepted as a good alternative instead of using Hibernate.
- Java ME/CDC1.1 is now really hot, must of us developer working in the Java Mobility area has waiting for that a long time. At JavaOne it was showed clearly with:
1) This the first release of a SavaJe based phone called Jasper S20, the first commercial handset to run all applications in Java technology
2) Netbeans support Java ME/CDC with this new NetBeans Mobility Pack 5.5 for CDC Preview
3) Sun released the Sun Java Wireless toolkit is for CLDC
4) Company like Nokia and Motorala will soon release more devices supporting the Java ME/CDC platform. I believe there will come many Java ME/CDC devices during 2007.
- Interesting is also there will soon come some new GUI toolkit, that will replace AWT for the Java ME/CDC platform: AGUI toolkit (JSR-209) and eswt (Nokia and IBM promote it a lot). Nokia talk about eSWT for Next Generation Java in Nokia platforms, but eSWT is not a JCP standard.
- Sun promoted the Netbeans platform very hard during JavaOne, in keynotes and in technical session and in the JavaOne Pavilion. Sun strategy is to move all there products into the Netbeans platform and I think they will have success with this.
- I became interested in the Open Source database Apache Derby after I went to a technical session about Derby. I realize Derby also supports the Java ME/CDC platform and for me it is really interesting. Later I got information from a developer that have using Derby with J9 on a Pocket PC 2003, he told me:
“I have really given up on Derby as the memory footprint is just too big. You need to 8-16 Mb to really operate properly. Derby will not load a 20,000 row table with one index in 8 meg including your app, that's just doing the inserts, never mind starting to do queries!.
However, I have just the other day discovered db4o... wow this is something else! the best bit of software I have seen since google earth.
It's not an SQL database it's an Object database. Rather than me harping on about it here, take a look for yourself, it's simply amazing.
I now have my application working great, it's faster, easier and handles even bigger tables... and currently all in under 3 meg. It does take a bit of getting used to, as they is no joins. But once you do, there is no going back!
- They talked about Project Tango, SUN engineers have working with Microsoft (WCF) engineers to ensure interoperability of enterprise features in Webservices. They have now Open Source the work they have done in Tango and they called it WSIT.
- I went to a technical session about Mobile Operational Management (JSR-232), just to JavaOne they released a Public Review about it. I think this JSR will be very important for us developer in the future.
- I also went to technical session about Java Card Next generation, it was really interesting, they plan to have a webserver on the JavaCard and support access to the JavaCard with normal IP, to simplify it for developer. Really cool but this JSR will come out during 2007 and products 2008, with normal delays….2009
- AJAX was hot during JavaOne, but not for me!!I think it is time for SWING applications, with Matisse it has really get easier to develop GUI application both for Java SE and Java ME/CDC1.1 platforms.
- It look like companies supporting Open Source have easier to get attention in the JavaOne pavilion, lots of people visit sun and Jboss’s booths, but not so many people in BEA, Borland booths. Of course these company will say they support Open Source, but the main different is that they sell there products.

Report from the NetBeans Software and JavaOne2006 conference in San Francisco
Some interesting things from those events:
- I got one SavaJe phone!!, now I can start using Java ME/CDC1.1 and the new AGUI toolkit (JSR-209).
- There is also a new releases of Netbeans that support the SavaJe phone called NetBeans Mobility Pack 5.5 for CDC Preview.
- Sun announced that Jboss now have also join Netbeans
- Netbeans 5.5 beta with support for Java EE 5.0 is released.
- Netbeans subversion beta is released, it look very nice in the demo.
- There was a demo of the Jackpot module, the module adds the capability to reengineer Java source code. You are also able to add new rules easy and share with others.
- Sun promote everyone to join JCP, I thought I should join JCP, but you couldn’t do that in the JavaOne pavilion, you have to download a pdf-file and sign it and then send it as a fax. Perhaps time to fix an easier solution and using Java for that?
- There was a demo of the NetBeans Enterprise Pack, you are then able to write SOA applications using XML, BPEL, and Java web services.
- Sun also continue to open source more things like: Sun Java Studio Creator, Sun Java System Portal Server, the Business Process Execution Language (BPEL) Engine and the NetBeans Enterprise Pack, as well as Sun's Java Message System (JMS)-based message queue and Web Services Interoperability Technology (WSIT). Everything moves into the Netbeans platform, I think it is a good strategy and the Netbeans platform getting stronger!!
- MSA for CLDC (JSR-248) became in Proposed Final Draft during JavaOne, they planned to have it final in august, we will see devices with support for that during 2006Q4/2007Q1. One change was support to run on top of Java ME/CDC1.1, the reason for that was to make it easier to migrate to MSA for CDC JSR-249 when it is ready. JSR-249 first public release plans to be released 2006Q4. MSA plans in the future to be upgrade every 18 months. One other change in JSR-248 was that there will be a will two versions of the MSA, one with a subset and one with whole MSA , read more about it here at C. Enrique Ortiz' Mobility Weblog.
- The new AGUI toolkit (JSR-209) planned to be final in august.
- Sun also released a Sun Java Toolkit for CDC, Early Access, it is like what Sun Java Wireless toolkit is for CLDC, the toolkit includes the emulation environments, documentation.
- In Nokia booth they demo next release of Carbide.j, version 1.5 that will support remote debugging on the phones. It look nice and it is very good to have.

Time for JavaOne!!!
Yesterday I went on tour “Muir Woods and Wine Country Tour”. It was a great tour with a lot of goods wines and I also liked the Muir woods with the world’s tallest trees.
But now it soon time for JavaOne, but first I will join the NetBeans Software Day at the 2006 JavaOne Conference, it is tomorrow.
See You at JavaOne and Netbeans day!!!
*****************sorry in swedish this part***************************
JavaOne, Får mig osökt att tänka på Orup... ” Nej du tar inte min Mercedes”
Nej du tar inte min JavaOne
JavaOne är min bäste vän
Du tar inte min JavaOne
Nej då kan du hälsa hem
Jag sa skjut min hund, prygla min katt, gör av med mina pengar på en lördagsnatt
Ta min fru, gör det du, men du om nån borde veta att: vill du göra mig riktigt illa
Så ta min JavaOne
Vill du åsamka mig smärta och förtvivlan utan gräns Vill du se hur mina tårar trillar, så ta min JavaOne

Free database for Java ME/CDC1.1 platform?
What about a free database that you could bundle with your Java ME/CDC application?
Is there anyone with support for the following platforms: Symbian 9, Microsoft Windows Mobile 5.0 (for Pocket PC) and SavaJe?
How do you bundle the application (Java App and database)?
Will it be support for that in tools like NetBeans Mobility Pack for CDC?

We need JSR-249, JSR-232 and JSR-246 now!!
But we need tools and devices for the Java ME/CDC1.1/Personal Profile platform1.1 to get this success.
So far Java ME/CDC1.0/Personal Profile 1.0 had no success in this area!
You can read things like Sun - Get you finger out! We NEED a Java Handheld / VM and Open letter to SUN to produce a JRE for Pocket PC
But a month ago the NetBeans Mobility Pack for CDC appeared!!
Netbeans was already is my favorite tool for the Java ME/MIDP 2.0 platform and now they also support Java ME/PP1.1 platform. I think now Netbeans is the best Java tool for mobility developing and it is also free!!
During 2007 I hope company like SonyErcisson, HP, Nokia, Palm, DELL will start produce more devices, with support for Java ME/CDC1.1/Personal profile 1.1 platform.
But support for Java ME/CDC1.1/PP1.1 is not enough for to get this success for the Java ME/Personal Profile platform. I think devices also need to support JSR-249 (Mobile Service Architecture Advanced) , JSR-232 (Mobile Operational Management) and JSR-246 (Device Management API).
JSR-249 provides guidelines to integrate J2ME JSRs in a uniform and predictable arrangement that is customized specifically for the advanced mobile handset. It will issue clarifications on certain components if necessary and will aim at reducing the number of available options.
It should also be possible to managed devices remotely with a modular architecture that enables extensibility after manufacturing. Push out new Java application, databases, OS updates and Java updates. In case of lost of device, lock the device remotely. It should also be possible to administration of users remotely.
All major mobile phone manufacturers worked together in order to define a 'Mobile Operational Management' concept (JSR-232). The OSGi Service Platform and the OMA DM (JSR-246) specifications provide the basis for building this standard for end-to-end management of CDC-enabled mobile handsets.
But JSR-249, JSR-232 and JSR-246 are not final yet, I hope they can speed up the process to get all these important JSR in a final stage. This is really important!!
I hope to hear news about that during JavaOne 2006 and it is now close to the 2006 JavaOne Conference!!! :-)
