我收到错误java.sql.SQLException:Exhausted ResultSet运行对Oracle数据库的查询.连接是通过Websphere中定义的连接池实现的.执行的代码如下:

            if (rs! = null) (
                while (rs.next ()) (
                    count = rs.getInt (1);
                )
            )

我注意到结果集包含数据(rs.next())

谢谢

  String storedPassword;
  if (ds == null) throw new SQLException("No data source");      
  Connection conn = ds.getConnection();
  if (conn == null) throw new SQLException("No connection");      

  try {
    conn.setAutoCommit(false);
    boolean committed = false;
    try {
      PreparedStatement passwordQuery = conn.prepareStatement(
        "SELECT passwd from USERS WHERE userz = ?");
      passwordQuery.setString(1, userToCheck);

      ResultSet result = passwordQuery.executeQuery();

      result.next();

      storedPassword = result.getString("passwd");                          

      conn.commit();
      committed = true;
    } finally {
      if …
