The easiest way to install JDK in Linux

with 3 comments

I have read lots of user posting at various pages and none of them would work.
Finally, I found a way to do this correctly and hope this will help to some of you.

Follow the simple steps:

1. To set the environment variables :

echo ‘export JAVA_HOME=/opt/btel/java/jdk1.5.0_16′ > /etc/profile.d/jdk.sh

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

2. You have to source the file you just created by typing:
source /etc/profile.d/jdk.sh

3. Test if Java environment is successfully installed by typing in this in the shell:
java -version

  1. You can just introduce a variable ORIG_PATH, to keep you path clean. Even after changing verrsion of (java) or anyother utility. By keeping all those in a single file.

    $ cat /etc/profile.d/jdk.sh
    JAVA_HOME=/opt/btel/java/jdk1.5.0_16

    export JAVA_HOME

    if [ ""$ORIG_PATH"" = """" ]; then
    export ORIG_PATH=$PATH
    fi

    PATH=$JAVA_HOME/bin:$ORIG_PATH
