Java command not found on Linux
You can add one of the Java path to PATH variable using the following command.
export PATH=$PATH:/usr/java/jre1.6.0_24/bin/
You can add this line to .bashrc file in your home directory. Adding this to .bashrc will ensure everytime you open bash it will be PATH variable is updated.
I had these choices:
-----------------------------------------------* 1 /usr/lib/jvm/jre-1.6.0-openjdk.x86_64/bin/java + 2 /usr/lib/jvm/jre-1.7.0-openjdk.x86_64/bin/java 3 /home/ec2-user/local/java/jre1.7.0_25/bin/java
When I chose 3, it didn't work. When I chose 2, it did work.
I found the best way for me was to download unzip then symlink your new usr/java/jre-version/bin/java
to your main bin as java.
