Installing Java 1.6 in Fedora

Download the Java SE Development Kit 6 Update 35 from the Oracle SE downloads page. Grab the RPM version for your architecture.

Run the file:

sh jdk-6u35-linux-*-rpm.bin

Install using the alternatives command.

alternatives --install /usr/bin/java java /usr/java/jdk1.6.0_35/bin/java 20000
alternatives --install /usr/bin/javaws javaws /usr/java/jdk1.6.0_35/bin/javaws 20000
alternatives --install /usr/bin/javac javac /usr/java/jdk1.6.0_35/bin/javac 20000
alternatives --install /usr/bin/jar jar /usr/java/jdk1.6.0_35/bin/jar 20000

Switch between Java 1.6 from Oracle and OpenJDK using alternatives --config. For example:

alternatives --config javac
