Manually install Sun Java on Debian
Wed, Dec 26, 2012 One-minute read
This is a tutorial on how to manually install Sun Java on Debian Linux. This may also work for other distributions but I cannot guarantee that.
cd /usr/lib mkdir jvm cd jvm
Download the latest .tar.gz file from http://www.java.com/de/download/manual.jsp and put in in the jvm directory.
tar -xvzf javafile.tar.gz
Now set the alternatives path. If you’re just installing the runtime environment, you only need the first line.
update-alternatives –install “/usr/bin/java” java “/usr/lib/jvm/TheExtractedFolder/bin/java” 1 update-alternatives –install “/usr/bin/javac” javac “/usr/lib/jvm/TheExtractedFolder/bin/javac” 1 update-alternatives –install “/usr/bin/javaws” javaws “/usr/lib/jvm/TheExtractedFolder/bin/javaws” 1
The last thing you have to do is to set the environment variables.
Add the following two lines at the end:
JAVA_HOME="/usr/lib/jvm/TheExtractedFolder export JAVA_HOME
Now activate it:
To test if everything works, execute the following commands:
echo $JAVA_HOME java -version
