Solution:

Set the path using:

C:\oracle\ora92\bin;C:\Program Files\Oracle\jre\Change it to the latest version you have installed(1.5.0 in my case)\bin;

The error has occured becuase you have compiled the program with a latest version and trying to run it using a version which is older version.... so make it to a new version.
