how to run eclipse by using a specified java path directory in eclipse not by the default Java path

I want to set java path to a specified java directory in eclipse, not the default installed java path. I want to run eclipse by using java from my specified path. But all the time eclipse runs by using the default installed java path. I have specified the Path in the "eclipse.ini" file but this path is not used by eclipse to run.. Please hep me...
This is my "eclipse.ini" file

-startup

plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar
