Answer 1

root's home folder is not under "/home". Change this

/home/root/java/jdk1.7.0_67/bin:/home/root/java/jdk1.7.0_67/bin

to

/root/java/jdk1.7.0_67/bin

Also,

/home/root/bin

should probably be

/root/bin

For similar reasons. When writing a script you can use $HOME which will expand to wherever the user's home directory happens to be. So,

PATH="$HOME/bin:$HOME/java/jdk1.7.0_67/bin"

Edit

I would not recommend that you link to java in $HOME/bin. Let's set a JAVA_HOME and move that to the front of the PATH like

export JAVA_HOME=$HOME/java/jdk1.7.0_67
export PATH="$JAVA_HOME/bin:$HOME/bin:$PATH"

Answer 2

sudo chmod a+x /usr/bin/java
sudo chmod a+x /usr/bin/javac
sudo chmod a+x /usr/bin/javaws
sudo chown -R root:root /usr/lib/jvm/jdk1.8.0

Answer 3

. .profile

If that doesn't work you can source your file.

source .profile 

note that source is a synonym of '.' (period).
