multiple JVM issue in application

Question

We have a desktop application where we are packing Application Jar and JRE as well to avoid Java dependency in customer machine.

But issue is if the customer is having the Java installed already in there Machine.we are facing issue like no class definition exception because of Java version dependencies for some class.

Now my question is how to launch the application always with the JRE that are packed with Application and ensure it is not use the System JRE if it is installed.
