	 * Whether the user has login or not will be judged in the form view.
	 * Only user has login, this method can be invoked. Otherwise, not.
	 * This method will get access to database (Orders table and Orders_Product table) and read all the histroy orders for the user.
	 * For each record in the ResultSet. this method will create an Order object for it.
	 * And For each product in the order, this method will create an product object for it and add it to the Collection class products of that order object. 
	 * 
	 * And then add the order object to an vector.
	 * At last return the vector. So we get all the history order of that user.

	 * Order
	 * @see Product
	 * @see Order

	 * @return a vector object that contains all the histroy orders of the user.
