Connection con = null;
	PreparedStatement pstmt = null;
	//Statement st = null;
	ResultSet rs = null;
	String sql = "SELECT * FROM CLIENT WHERE ID=? ";
 
	DBConnection dbConnection = new DBConnection();
	con = dbConnection.getDBConnection(USER, PWD, URL, DRIVER);
	try {
	    pstmt = con.prepareStatement(sql);
	    pstmt.setInt(1, 62);
	    rs = pstmt.executeQuery(sql);
	    while (rs.next()) {
		System.out.println("Client name: " + rs.getString(2));
	    }
	    rs.close();
	    pstmt.close();
	} catch (SQLException e) {
	    e.printStackTrace();
	    if (con != null) {
		try {
		    con.rollback();
		} catch (SQLException e1) {
		    e1.printStackTrace();
		}
	    }
	} finally {
             dbConnection.closeConnection(con);
	}

et j'obtiens toujours l'erreur suibante:
