a quick and eazy way to install java under linux
1. download jre or jdk from www.java.com
2. create a directory to hold the versions
# mkdir /usr/java
3. extract the tar file under the directory
# tar -xzvf jre-7u45-linux-x64.tar.gz -C /usr/java # ln -s /usr/java/jre1.7.0_45 /usr/java/jre-latest
4. the last part is to create links in the system in order to
make sure it uses this new java version we just extracted .
