change directory to Downloads directory to install JDK.

localhost:/home/hadoop/Downloads # rpm -ivh  jdk-7u25-linux-x64.rpm

All essential java commands seem works fine but there is something we have to commit, finally: Setting JAVA_HOME directory in PATH.

Suse stores all its profile information /etc/profile.d directory, grant access under the /etc/profile.d with root.

localhost:/etc/profile.d # su

Create jdk.sh file under /etc/profile. and write output of below echo command.

# echo 'export JAVA_HOME=/usr/java/jdk1.7.0_25'>/etc/profile.d/jdk.sh

Append output of echo command.

# echo 'export PATH=$JAVA_HOME/bin:$PATH'>>/etc/profile.d/jdk.sh

trigger jdk.sh

# source /etc/profile.d/jdk.sh

Finally, You have to logout and login to see the effect with your own user.
