Java Programming

Hi all,

I'm trying to access the Windows Registry through java using the ice registry package com.ice.jni.registry.
I'm getting this error:

*com.ice.jni.registry.RegistryException: Registry API Error 6, 'invalid handle' -
'RegQueryValueEx()'*

My code is as follows:

import java.util.*;
import com.ice.jni.registry.*;

class regSearch
{
	public static void main(String[] s)
	{
		System.loadLibrary("ICE_JNIRegistry");
		RegistryKey oRegKey = new RegistryKey(4,
		"\\HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\App Management\\ARPCache");
		//"\\HKEY_LOCAL_MACHINE\\Software\\Microsoft\\Windows\\CurrentVersion\\Uninstall");
		
		String str = oRegKey.getFullName();
		
		System.out.println(str);
		
		try 
		{
			System.out.println(oRegKey.hasDefaultValue());
			//Enumeration keyElements = oRegKey.keyElements();
		
		//	System.out.println(keyElements.nextElement());
		} 
		catch (RegistryException e) 
		{
			// TODO Auto-generated catch block
			System.out.println("You are getting an error: \n"+e);
		}
	}
}

I'm trying to fetch information about softwares that are currently installed on the PC. But I'm getting this error right now..so I can't go ahead. Please help me for the same..I've got to finish this by today..

Thanx in advance,
Rave.
