How to install Java on Linux

 This is how I install java on Linux if you don't want to install it using yum.

download java from http://www.oracle.com/technetwork/java/javasebusiness/downloads/java-archive-downloads-javase14-419411.html
jre-1_5_0_12-linux-amd64.bin
chmod +x jre-1_5_0_12-linux-amd64.bin
./jre-1_5_0_12-linux-amd64.bin
[root@duim001zatcrh ~]# alternatives --install /usr/bin/java java /usr/lib/jvm/jre1.5.0_12/bin/java 1
[root@duim001zatcrh ~]# alternatives --install /usr/bin/java java /usr/java/jre1.5.0_12/bin/java 2
[root@duim001zatcrh ~]# alternatives --config java
