How to Parse JSON from Java Object

private static void BeanToJson(Object object, JSONObject json) throws Exception
{
	if(object != null)
	{
		PropertyDescriptor[] property = null;
		property = Introspector.getBeanInfo(object.getClass(),Object.class).getPropertyDescriptors();
		for(PropertyDescriptor each : property)
		{
			try
			{
				String propertyName = null;
				Object obj = each.getReadMethod().invoke(object);
				if(ClassUtils.isPrimitiveOrWrapper(obj.getClass()) || obj instanceof String)
				{
					propertyName = each.getName();
					json.put(propertyName,obj);
				}
				else if(obj instanceof ArrayList)
				{
					ArrayList<?> arrayList = (ArrayList<?>) obj;
					JSONArray jsonArray = new JSONArray();
					propertyName = each.getName();
					for(int index =0; index <  arrayList.size(); index++)
					{
						JSONObject newJson = new JSONObject();
						BeanToJson(arrayList.get(index),newJson);
						jsonArray.put(newJson);
					}
					json.put(propertyName, jsonArray);
				}
				else
				{
					JSONObject newJson = new JSONObject();
					propertyName = each.getName();
					BeanToJson(obj,newJson);
					json.put(propertyName,newJson);
				}
			}
			catch(Exception e)
			{
				e.printStackTrace();
