O que acontece? Erro? Exception? Nada?

#3

Você está fazendo forward. Não precisa fazer o sendRedirect.

#4

mude isso

    
            request.getSession().setAttribute("vo",vo);  
              
              
              
            RequestDispatcher rd = request.getRequestDispatcher("Mostrabusca.jsp");  
            rd.forward(request, response);  
              
            response.sendRedirect("Mostrarbusca.jsp");

para isso

    
            request.setAttribute("vo",vo);  
              
              
              
            RequestDispatcher rd = request.getRequestDispatcher("Mostrabusca.jsp");  
            rd.forward(request, response);  
              
            //response.sendRedirect("Mostrarbusca.jsp");

tenta fazer assim pra ver se funciona

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {  
          
	    HttpSession session = request.getSession();

              
            QuartoDAO DAO = new QuartoDAO();  
              
            List<QuartoVO> vo = new ArrayList<QuartoVO>();  
          
            QuartoVO quartovo = new QuartoVO();  
                      
            try {  
                  
                vo.addAll(DAO.mostrarEstadoQuartos(quartovo));  
              
      
              
            } catch (SQLException e) {  
                // TODO Auto-generated catch block  
                e.printStackTrace();  
            } catch (ClassNotFoundException e) {  
                // TODO Auto-generated catch block  
                e.printStackTrace();  
            }  
              
              
			session.setAttribute("vo",vo);            
              
            response.sendRedirect("Mostrarbusca.jsp");  
    }  
      
      
       
}
