例外：不允许操作后的ResultSet关闭，同时从两个表

我试图从一个try catch块内，但通过SQLEXCEPTION操作两个表不准亚特的ResultSet关闭取值取值。例外：不允许操作后的ResultSet关闭，同时从两个表

try { 
     JdbcConnection.connectDB(); 
     String sql = "SELECT * FROM projects where username = '" + username 
       + "' && project_id ='" + p_id + "'"; 
     String sql1 = "SELECT * FROM rewards where project_id ='" + p_id 
       + "'"; 

     ResultSet rs = JdbcConnection.stmt.executeQuery(sql); 
     ResultSet rs1 = JdbcConnection.stmt.executeQuery(sql1); 
     while (rs.next()) { 
      fname.setText(rs.getString(3).toString()); 
      lname.setText(rs.getString(4).toString()); 
      uname.setText(rs.getString(5).toString()); 
      pwd.setText(rs.getString(6).toString()); 
      addr.setText(rs.getString(7).toString()); 
      ctry.setText(rs.getString(8).toString()); 
      acc_no.setText(rs.getString(9).toString()); 

     } 
     while (rs1.next()) { 
      rwd1.setText(rs1.getString(2)); 
      rwd2.setText(rs1.getString(4)); 
      rwd3.setText(rs1.getString(6)); 
      rwd4.setText(rs1.getString(8)); 
      rwd5.setText(rs1.getString(10)); 
     } 
     rs.close(); 
    } catch (SQLException sqlexc) { 
     JOptionPane.showMessageDialog(null, "" + sqlexc); 
    }

在代码中会出现什么问题？

的printStackTrace（）

请张贴的异常堆栈跟踪。 –

@SotiriosDelimanolis我有张贴堆栈跟踪以及请帮我可能是什么问题。 –

什么是116？ –

我想你应该rs1创建不同的语句（stmt）。
