Установка java

[AzogConqueror 13]

Пробую установить нужную вверсию Java по инструкциям

 

 

 I'm assuming you've already downloaded both tars, JDK and JRE. So, here's what you have to do:
First create a directory to hold your Java JDK and JRE binaries:

Code:

sudo mkdir -p /usr/local/java

Then, copy the Java binaries into the /usr/local/java directory:

Code:

cd folder_where_your_tars_are_located
sudo cp -r jdk-7u21-linux-i586.tar.gz /usr/local/java
sudo cp -r jre-7u21-linux-i586.tar.gz /usr/local/java
cd /usr/local/java

Unpack the compressed Java binaries, in the directory /usr/local/java:

Code:

sudo tar xvzf jdk-7u21-linux-i586.tar.gz
sudo tar xvzf jre-7u21-linux-i586.tar.gz

Edit the system PATH file /etc/profile and add the following system variables to your system path. Use nano, geany, gedit or any other text editor, as root:

Code:

sudo geany /etc/profile

and add the following lines below to the end of your /etc/profile file:

Code:

JAVA_HOME=/usr/local/java/jdk1.7.0_21
PATH=$PATH:$HOME/bin:$JAVA_HOME/bin
JRE_HOME=/usr/local/java/jre1.7.0_21
PATH=$PATH:$HOME/bin:$JRE_HOME/bin
export JAVA_HOME
export JRE_HOME
export PATH

Save the /etc/profile file and exit.
After that, notify your Ubuntu system where your Java JDK/JRE are located:

Code:

sudo update-alternatives --install "/usr/bin/java" "java" "/usr/local/java/jre1.7.0_21/bin/java" 1
sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/local/java/jdk1.7.0_21/bin/javac" 1
sudo update-alternatives --install "/usr/bin/javaws" "javaws" "/usr/local/java/jre1.7.0_21/bin/javaws" 1

and that Java JDK/JRE must be the default Java:

Code:

sudo update-alternatives --set java /usr/local/java/jre1.7.0_21/bin/java
sudo update-alternatives --set javac /usr/local/java/jdk1.7.0_21/bin/javac
sudo update-alternatives --set javaws /usr/local/java/jre1.7.0_21/bin/javaws

Finally, reload your system wide PATH /etc/profile by typing the following command:

Code:

. /etc/profile 

 

 

 

 

В итоге ничего не работает

 

 

вожусь уже пару часов все не как не пойму что не так делаю
