SITools2 Installation on Debian 9¶

For maintenance reasons (especially system updates), we test the installation of SITools2 on the last version of debian (Stretch which is currently not yet stable).
To be reproduced on the SITools2 VMs where version 9 will be released "stable"...

Installation of openjdk-7¶

SITools2 is incompatible with Java 8
We have to install Java 7. The procedure is a little bit tricky cause the openjdk-7 package doesn't exist for Debian 9.

First, we add a repository containing the package (experimental!) for Stretch (caliu repository) :

cat /etc/apt/sources.list
# deb http://inf-mirror/debian/ stretch main

deb http://inf-mirror/debian/ stretch main contrib non-free
deb-src http://inf-mirror/debian/ stretch main contrib non-free

deb http://ftp.caliu.cat/debian/ experimental main contrib non-free
deb-src http://ftp.caliu.cat/debian/ experimental main contrib non-free

deb http://security.debian.org/debian-security stretch/updates main
deb-src http://security.debian.org/debian-security stretch/updates main

But the installation doen't work due to the missing of libjpeg8 library in Stretch. In order to solve this libjpeg8 problem, we have to install the 'sid' package version, here :
https://packages.debian.org/fr/sid/amd64/libjpeg8/download

dpkg -i libjpeg8_8d1-2_amd64.deb

Finally, just do :

aptitude install openjdk-7-jdk

Another way to install openjdk-7 in debian 9¶

• Download the java JDK 7
  

  sudo wget --no-cookies --header "Cookie:oraclelicense=accept-securebackup-cookie" --user=Oracleaccount-username --ask-password  http://download.oracle.com/otn/java/jdk/7u80-b15/jdk-7u80-linux-x64.tar.gz
  

  • Another way to download JDK 7:
    

       curl -L -C - -b "oraclelicense=accept-securebackup-cookie" -O https://download.oracle.com/otn/java/jdk/7u80-b15/jdk-7u80-linux-x64.tar.gz
    
    

• Extract file using below command
  

  tar -xvzf jdk-7u80-linux-x64.tar.gz
  

• Move extracted folder in JDK parent directory 'usr/lib/jvm'
  

  sudo mv jdk1.7.0_80 /usr/lib/jvm/jdk1.7_80
  

• Add the below system variables to PATH in /etc/profile
  

  JAVA_HOME=/usr/local/java/jdk1.7.0_80
  JRE_HOME=$JAVA_HOME/jre
  PATH=$PATH : $JRE_HOME/bin : $JAVA_HOME/bin
  export JAVA_HOME
  export JRE_HOME
  export PATH
  

  
  then
  

  . /etc/profile
  

Now run below commands to update alternatives

sudo update-alternatives --install "/usr/bin/java" "java"  "/usr/lib/jvm/jdk1.7.0_80/bin/java" 

What is below is optional

sudo update-alternatives --install "/usr/bin/javac" "javac"  "/usr/lib/jvm/jdk1.6.0_31/bin/javac" 1

sudo update-alternatives --install "/usr/bin/javaws" "javaws"  "/usr/lib/jvm/jdk1.6.0_31/bin/javaws" 1

To see all JDK installed versions use 'sudo update-alternatives --config java' command and your output should be something like this:

sudo update-alternatives --config java
There are 4 choices for the alternative java (providing /usr/bin/java).

  Selection    Path                                            Priority   Status
------------------------------------------------------------
  0            /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java   1081      auto mode
  1            /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java   1081      manual mode
  2            /usr/lib/jvm/jdk1.7.0_76/jre/bin/java            1         manual mode
  3            /usr/lib/jvm/jdk1.7.0_80/bin/java                0         manual mode
* 4            /usr/lib/jvm/jdk1.7.0_80/jre/bin/java            1         manual mode
