Basically you have to use JNI to write to the registry, or use some 3rd party tools like the one objects posted.

If you want to write your own JNI library to do this, let me know and I can walk you through it.

just create your dll-function in C/C++ , which will write data to registry. And then use JNI to call it, and pass parameters it needs to write to registry. Thats simple :)

THANKS TO ALL ,
I solved it by using preferences api.Since i have to give away points even though was not helping me to my requirement, i will split to all of u.

import java.util.prefs.Preferences;

public class UsingReg {

public static final String REALKEY= "com.hnl.htms";

public static void main(String[] args){
  new UsingReg().doit();
}

public void doit() {
  // write into HKEY_CURRENT_USER\Software\Javasoft\Prefs\com.hnl.htms
  Preferences p = Preferences.userRoot();
  p.put(REALKEY, "1234567767656590298");

  // read back from HKEY_CURRENT_USER
  System.out.println(p);
  System.out.println(p.get(REALKEY, "Error While Writing"));

  // write into HKEY_LOCAL_MACHINE\Software\Javasoft\Prefs\com.hnl.htms
  p = Preferences.systemRoot();
  p.put(REALKEY, "1234567767656590298");
 //Preferences c = Preferences.userRoot().node("com.hnl.htms/Company");
 // c.put("CmpName","Sno");
  // read back from HKEY_LOCAL_MACHINE
  System.out.println(p);
  System.out.println(p.get(REALKEY, "Error No Value"));
  }
}
