Question: My code throws

```
java.sql.sqlRecoverableException: Sentencia cerrada: next

```

which, in English, I guess it would be:

```
java.sql.sqlRecoverableException: Closed statement: next

```

This is my code:

```
public TransactionArray() throws SQLException {

  /* Obtenemos la tabla de transacciones. */
  Connection connection;
  connection = ConnectionManager.getConnection(STATISTIC_DATA_BASE);
  Statement stmt = null;
  String query =
          "select * " +
          "from " + "dCellStatistic" + ".F_Transaction";
  ResultSet rs = null;
  try {
     stmt = connection.createStatement();
     rs = stmt.executeQuery(query);
  } catch (SQLException e ) {
     e.printStackTrace();
  } finally {
     if (stmt != null) { stmt.close(); }
  }

  /* Construimos las transacciones a partir de los registros. */
  List<Transaction> transactionList = new ArrayList<Transaction>();
  while (rs.next()) { //THE PROBLEM ARISES IN THIS LINE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
     transactionList.add(new Transaction(rs));
  }
  array = transactionList.toArray(new Transaction[transactionList.size()]);

```

}

Any clues of what I may be doing wrong? I have seen two threads on Code Ranch about similar issues, but none of them seemed to provide a solution for my case.

Answer: 
You are closing the statement prior to retrieving the information from the result set. Move the `stmt.close()` call after the `rs.next()` loop (but keep the try/finally).
Since the fixed code doesn't fit in a comment, I publish it here for future reference.

```
public TransactionArray() throws SQLException {
  List<Transaction> transactionList = new ArrayList<Transaction>();

  /* Obtenemos la tabla de transacciones. */
  Connection connection;
  connection = ConnectionManager.getConnection(STATISTIC_DATA_BASE);
  Statement stmt = null;
  String query =
          "select * " +
          "from " + "dCellStatistic" + ".F_Transaction";

  /* Construimos las transacciones a partir de los registros. */
  ResultSet rs;
  try {
     stmt = connection.createStatement();
     rs = stmt.executeQuery(query);
     while (rs.next()) {
        transactionList.add(new Transaction(rs));
     }
  } catch (SQLException e ) {
     e.printStackTrace();
  } finally {
     if (stmt != null) {
        stmt.close();
     }
  }
  array = transactionList.toArray(new Transaction[transactionList.size()]);
}

```
