Hi zolive33,

Install B4J on Ubuntu step by step :

1-Remove OpenJdk (not compatible with JavaFX)
sudo apt-get purge openjdk*

2-install Java 7 Jdk (for linux)
Download 32bit or 64bit Linux "compressed binary file" (.tar.gz)
Main page : http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html
Linux x86 -> http://download.oracle.com/otn-pub/java/jdk/7u51-b13/jdk-7u51-linux-i586.tar.gz
or Linux x64 -> http://download.oracle.com/otn-pub/java/jdk/7u51-b13/jdk-7u51-linux-x64.tar.gz

Uncompress it:
Linux x86 -> tar -xvf jdk-7u2-linux-i586.tar.gz (32bit)
or Linux x64 -> tar -xvf jdk-7u2-linux-x64.tar.gz (64bit)

move the JDK 7 directory to /usr/lib:
sudo mkdir -p /usr/lib/jvm
sudo mv ./jdk1.7.0_02 /usr/lib/jvm/jdk1.7.0_51

Create links
sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jdk1.7.0_51/bin/java" 1
sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/lib/jvm/jdk1.7.0_51/bin/javac" 1
sudo update-alternatives --install "/usr/bin/javaws" "javaws" "/usr/lib/jvm/jdk1.7.0_51/bin/javaws" 1

Perhaps you have to update permissions of the executables (not necessary for me) :
sudo chmod a+x /usr/bin/java
sudo chmod a+x /usr/bin/javac
sudo chmod a+x /usr/bin/javaws
sudo chown -R root:root /usr/lib/jvm/jdk1.7.0_51

Active links
sudo update-alternatives --set "/usr/bin/java" "java" "/usr/lib/jvm/jdk1.7.0_51/bin/java"
sudo update-alternatives --set "/usr/bin/javac" "javac" "/usr/lib/jvm/jdk1.7.0_51/bin/javac"
sudo update-alternatives --set "/usr/bin/javaws" "javaws" "/usr/lib/jvm/jdk1.7.0_51/bin/javaws"

3-install JavaFX (for linux)
Main page : http://www.oracle.com/technetwork/java/javafx/downloads/index-jsp-136193.html
Linux x86-> http://download.oracle.com/otn-pub/....1-b35/javafx_scenebuilder-1_1-linux-i586.deb
or Linux x64 -> http://download.oracle.com/otn-pub/...1.1-b35/javafx_scenebuilder-1_1-linux-x64.deb
Execute <file>.deb

4-install wine 1.6
sudo add-apt-repository ppa:ubuntu-wine/ppa
sudo apt-get update
sudo apt-get install wine1.6

5-Active wine in 32bits then install dotnet 2.0:
WINEARCH=win32 WINEPREFIX=$HOME/.wine wine do_not_exists 2>/dev/null
WINEARCH=win32 WINEPREFIX=$HOME/.wine winetricks dotnet20

6-install jdk7 for windows:
http://download.oracle.com/otn-pub/java/jdk/7u51-b13/jdk-7u51-windows-i586.exe

8-at last... install B4J:
http://www.b4x.com/android/b4j.html
install B4J
run wine config, add programm B4J.exe and set dll gdiplus to native.

NB: you can't execute JavaFX directly from B4J. I think it's possible but i don't know how?
you can start JavaFX with Ubuntu Launcher.

In a few days I'll publish a shell script to automatise installation. Please be patient ;-)

I know old thread but why do you need jdk for windows wjem you are installing on ubuntu?

Because the IDE is running under Wine so the JDK needs to as well to run some IDE/Compiler tools.

Because the IDE is running under Wine

:O For some reason I believed it could run natively on linux as a B4X solution itself.
