I have’nt introduced one of the most fascinate activities for Japanese RPi community – Eject command Users group by Ouchi Akira , @akkiesoft though I have known him for a long while ๐Ÿ™‚

Eject Command is doing something through pushing and pulling out CD’s tray – ex.it powering on/off air conditioners.for more info please check the link his activities and if you are interested please join his community.

Akkie!

I’m remembering akkiesoft playing around at Open Source Conference and Raspberry Jam – was very cool thus make Eben and us happy.and has become famous RPi communities all over the world.Liz mentioned on official blog and said the he was ‘great’.now he going and work toward ‘the first step’.

Next he should blog in Engish and disuss with Eben ๐Ÿ™‚ ,Akkie (โ˜ ีžเจŠ ีž)โ˜ ใ‚ฆใ‚ฃใƒผใƒณ

Last week we hold Raspberry Jam #2 in Tokyo.We had the first foreigner guest from Australia.I was much surprised…BUT she told she misunderstood our event.I was too much sorry for her.we talked about the business in Japan and what and how Raspberry PI was in Japan.

We talked cases for PI,OMX player on PI and how to watch the pet through twitter using Raspberry PI..great time,and wondering using Famicon Cases for Raspberry PI.
for more detail please check the pics.

Next month we welcome the biggest guest,Eben Upton,founder of Raspberry PI Foundation.

According to JavaFX Advent Calendar 2012,I would write JavaFX on PI.

Note you should use ‘Hard-float’ not ‘Soft-float’ as you usually use for Oracle Java.Just download it ,untar and get the sample files.

Well just wondering no recognizing VNC and Wireless Keyboard and mouse.say ‘device error’ while executing.I haven’t tried the sample on github.but other samples on Oracle JavaFX site doesn’t work good the samples always say ‘glGetError 0x500’ – an OpenGL Error.wondering why they say.

here are pics executing.but you should read the known issues.there are too much I can’t help giving up…need to much more time for developing just Oracle teasing us.

Finally we got the Japanese PI forum at the official website!I have been keeping in touch with Eben and Liz,founders of the Raspberry PI Foundation.They ware here in Japan last month.they would present a talk here! I asked him to have it to encourage Japanese community,He was willing to add into official forum and add me as one of ย ‘moderator’ for the forum!

feel free to post,much appreciate if you help with posting the issue to encourage Japanese community.

According to ‘Java Advent Calendar’ I just blog Getting Started Java on Raspberry PI.

First you should choose Java – Oracle Java or OpenJDK.if you choose Oracle Java you should use ‘Soft-float Debian wheezy’,or wont work on ‘Hard-float’,is a bit older.if you use Rev.B w/512MB after installation to SD,you should replace start.elf as follows.

git git://github.com/raspberrypi/firmware.git
cd firmware;git checkout;git checkout -b 48f8bb0e47
cd boot
cp armXXX_start.elf /Volume/$SD_NAME/start.elf (Mac OS X)
*arm496_start.elf or arm448_start.elf is prefer to use.

and please be careful installing JBOSS,use Oracle Java Embedded Suite for the installation.

if you use OpenJDK,you don’t have to.only download ‘Hard-float Raspbian wheezy’ and get it with apt-get.if you use jetty you might use JamVM,lightweight VM for Embedded.the installation is as follows.

sudo apt-get install openjdk-7-jdk git libtool autoconf automake
git clone git://git.berlios.de/jamvm
cd jamvm
./autogen.sh –with-java-runtime- library=openjdk7
make
sudo cp src/.libs/libjvm.so /usr/lib/jvm/java-7-openjdk-armhf/jre/lib/arm/jamvm/

hope to make it with Java you should also check my slideshare http://www.slideshare.net/masafumi_ohta/raspberry-pi-on-java-20121110

JBOSS on PI

According to ‘Java EE Advent Calendar by Japan Java UG.so I would blog JBOSS on PI but very slow so need some turnings.

Checking website it needs Oracle Java and ‘root’ privilege so I need Soft-ABI rasbian.and change start.elf to use 512MB (if you have Rev.B w/512MB)

Download Oracle Java Embededd Suite:http://download.oracle.com/otn-pub/java/JES/7.0-b11/jes-7.0-ga-bin-b11-linux-arm-runtime-15_nov_2012.zip
(not jdk,say ‘server VM only support ARM7+’)

And Download JBoss AS7:http://download.jboss.org/jbossas/7.1/jboss-as-7.1.1.Final/jboss-as-7.1.1.Final.zip

in my case exacting the files to /opt

needs .bash_profile and active with ‘source .bash_profile’ for root
add to JAVA_HOME PATH to .bash_profile,

JAVA_HOME=/opt/jes7.0/jre
PATH=$PATH:$JAVA_HOME/bin
export JAVA_HOME PATH

run standalone.sh as root:
#/opt/jboss-as-7.1.1.Final/bin/standalone.sh -b 192.168.100.8 (your PI IP address)

=========================================================================

JBoss Bootstrap Environment

We Japanese Raspberry PI Users Group will hold First Raspberry Jam in Tokyo.I am eager to hold for networking Raspberry PI Users in Tokyo sharing the thought,ideas or some.All are welcome – Apps,Cases,OSes,Langs..Beginners are welcome,needless to say,Intermediates and Advances.all you needs ‘Love for PI’ – be a fan for PI to get started the PI.fortunately you know Raspberry PI is for studying how computer works – not for business – not needed any speeds,performances.Making Cases for PI is great contribution for the PI’s communities,right?Not needed some IT skills you can getting started with PI!
We very welcome youngers,girls encouraging our JP RasPI UG.why dont you join us and much appreciate if you would come.

For more info please check the link.
