        Player p = e.getPlayer();
        try {
            PreparedStatement search = (PreparedStatement)SqlConnector.con.prepareStatement("SELECT * FROM `jogadores` WHERE `Nick`='"+ p.getName() + "' OR `UUID`='" + p.getUniqueId().toString()+"'");
            ResultSet rs = search.executeQuery();
            if(rs.next()) {
                if(rs.getString("mute").equals("true")) {
                    String motivo = rs.getString("mutemo");
                    int tempo = rs.getInt("mutetemp");
                    if(tempo == 0) {
                        p.sendMessage("§cVoce esta mutado permanentemente por: " + motivo);
                        e.setCancelled(true);
                    }else {
                        long milisec = rs.getLong("mutesec");
                        long amilisec = System.currentTimeMillis();
                        long temppmili = tempo * 60000;
                        long tempomutado = amilisec - milisec;
                        if(tempomutado >=temppmili) {
                            p.sendMessage("not muted2");
                            mutados.remove(p.getName());
                        }else {
                            mutados.add(p.getName());
                            tempomutado = tempomutado / 60000;
                            long temporest = tempo - tempomutado;
                            p.sendMessage("§cVoce esta mutado por mais " + temporest + " minutos por: " + motivo);
                        }
                    }
                }else {
                    e.setCancelled(false);
                    p.sendMessage("not muted");
                }
            }
        } catch (SQLException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();

Ok, but, tell me please, what another plugin?

 

Ok but if tempo is 0 the mute is permanent. So legend chat? EssentialsChat?
