You need to update PATH variable to include the bin directory of your correct JDK .

Make sure your PATH has your JDK bin folder before any other JDK/JRE installation by adding it in begining of your PATH.

Run below from your Korn or bash shell (console):

export JAVA_HOME=jdk-install-dir 

export PATH=$JAVA_HOME/bin:$PATH

set JAVA_HOME =C:..... the path where your java 7 is present upto the bin location

example

SET JAVA_HOME=C:\Program Files\Java\jdk_1.7.1
SET JAVA=%JAVA_HOME%\bin\java

Maybe you have just installed a 1.6 JDK and a 1.7 JRE. To keep both at the same level, just install the 1.7 JDK. Try this command:

su -c "yum install java-1.7.0-openjdk"
