Problems with JAVA installation

I need to install the latest version of JAVA on my RHEL machine. 6.5

I visit the java site at
http://java.com/en/download/linux_manual.jsp?host=java.com&returnPage=http://www.nvidia.com/Download/Scan.aspx?lang=en-us&locale=en-US
Then follow the link
Linux x64 RPM * filesize: 31.9 MB
http://javadl.sun.com/webapps/download/AutoDL?BundleId=81811

Then everything looks ok.. Statement that download is completed.

Then I go to the NVIDIA page to get the latest GeoForce driver at
http://www.nvidia.com/Download/index.aspx?lang=en-us

I selected option 2 . This is a automatic driver finder
http://www.nvidia.com/Download/Scan.aspx?lang=en-us

Btu I get an error.. That I do not have the JAVA isntalled with the followign message.

he NVIDIA Smart Scan requires the latest version of Java
Click on the 'Java' icon to install java Install Java

I cant figure wha tI am doing wrong. I go to the Application manager and type JAVA. Apparently it is install. SO why is nothing requiring java works?
