Update your Java version and make it compatible with JRE.

For detail description follow this links:

http://javarevisited.blogspot.in/2011/07/javalangunsupportedclassversionerror.html

It is actually simple - you need to install BOTH JRE / JDK with the same version.

JRE 6 -> JDK 6

JRE 7 -> JDK 7

And so on

or

Your java version should be equivalent or greater than JRE
