  String url = "jdbc:informix-sqli://192.168.1.100:8888/ywfx:INFORMIXSERVER=ywfx_tcp;user=ywfx;password=ywfx";

        }
        catch (java.lang.ClassNotFoundException e) {
        System.err.println("Connect1():" + e.getMessage());
        }
  }

  public ResultSet executeQuery(String sql) {
    rs = null;
    try {
        conn = DriverManager.getConnection(url);
        Statement stmt = conn.createStatement();
        rs = stmt.executeQuery(sql);
        }
        catch (SQLException ex) {
        System.err.println("co.executeQuery:" + ex.getMessage());
        }
        return rs;
  }

  public ResultSet branch() {
     String sql="select branch_no,branch_name from branch";
     try{
          conn = DriverManager.getConnection(url);
          PreparedStatement ps = conn.prepareStatement(sql);
          ResultSet res = ps.executeQuery();
          return res;
        }
        catch(Exception e){
          return null;
        }
    }
}

请问如何在jsp网页中获取return res的返回值。
