	 int num=Integer.parseInt(request.getParameter("num"));
     int messageId=Integer.parseInt(request.getParameter("messageId"));
     MessageManagerDAO messagedao=new MessageManagerDAO();
     if(num==1){
     boolean flage=messagedao.deleteMessageById(messageId);
       if(flage){
    	 return "/jsp/addmessage.do";
            }
        else{
