    Default Set Up Java Enviroment

    Hi All,

    I am new to java and I will start from JSF because I have a bit fundamental.
    But unfortunatley I have problem to set up java enviroment.
    I am using linux:

    I am reading steps from an article. Here they are

    Verify Java installation on your machine

    $ java -version

    I see that java already installed at my pc, terminal screen is below:

    java version "1.7.0_25"
    OpenJDK Runtime Environment (IcedTea 2.3.10) (7u25-2.3.10-1ubuntu0.13.04.2)
    OpenJDK 64-Bit Server VM (build 23.7-b01, mixed mode)


    Now I want to apply below commands after findign where my java is installed!

    export JAVA_HOME=/usr/local/java-current
    export PATH=$PATH:$JAVA_HOME/bin/


    when I check /etc folder, I see following folders

    java
    java-6-openjdk
    java-7-openjdk


    I assume that java-7-openjdk is the folder I look for, so I apply following commands:

    export JAVA_HOME=/etc/java-7-openjdk[
    export PATH=$PATH:$JAVA_HOME/bin/


    I also set up Maven.
    when I write terminal to see mvn version as follow as I get error

    mvn --version
    Error: JAVA_HOME is not defined correctly.
    We cannot execute /etc/java-7-openjdk/bin/java


    I know that there is no folder called /etc/java-7-openjdk/bin/java but then what I must I write to set java home?
