用数据库条目填充下拉列表

   <% }     %></select>

在您的JSP中使用它。Servlet代码

 ArrayList<String> list = new ArrayList<String>(); out.println("HI GROUP MEMBER"); String query="Select GNAME from tbGroup"; ps = con.prepareStatement(query); rs=ps.executeQuery(); while(rs.next()){     list.add(rs.getString("GNAME")); } request.setAttribute("res1",list); RequestDispatcher rd= context.getRequestDispatcher("GroupLoginScreen.jsp"); rd.forward(request, response);
