    <p>I wrote this class (from examples) to download the header of all the files contained in a remote FTP folder. It works well, but when it approaches to download the file #146 it stops with a NullPointException. The file #146 exists and I can download it as a single file actually.</p> <p>In the method remotePathLong contains all the remote folders written in a single line and spaced with the space character.</p> <pre><code>public void downloadHeader(String remotePathLong, String destPath, int bytes) { String remotePath; FTPFile[] fileList; String[] fileNameList; FTPClient ftpClient = new FTPClient(); try { ftpClient.connect(server); ftpClient.login(user, pass); ftpClient.enterLocalPassiveMode(); ftpClient.setFileType(FTP.BINARY_FILE_TYPE); int indice = 0; int iP = 1; File downloadFile; String destFile; String remoteFile; byte[] bytesArray; int bytesRead = -1; while ((remotePath = getPath(remotePathLong, iP)) != null) { System.out.println("Loading file list from the server....."); fileNameList = ftpClient.listNames(remotePath); for (String file : fileNameList) { indice += 1; System.out.println(indice + " - Downloading: " + file); //Select files destFile = destPath.concat(file); downloadFile = new File(destFile); outputStream = new BufferedOutputStream(new FileOutputStream(downloadFile)); //Download remote file (from ftp) remoteFile = remotePath.concat(file); inputStream = ftpClient.retrieveFileStream(remoteFile); bytesArray = new byte[bytes]; bytesRead = inputStream.read(bytesArray); outputStream.write(bytesArray); //Save into file outputStream.close(); inputStream.close(); iP += 1; } } } catch (IOException ex) { } final{ try { if (ftpClient.isConnected()) { ftpClient.logout(); ftpClient.disconnect(); } } catch (IOException ex1) { System.out.println("Error: " + ex1.getMessage()); } } </code></pre> <p>when it reaches bytesRead = inputStream.read(bytesArray), at the iteration #146 it gives the error. But if at the same iteration i reinitialize the connection it works. Does anybody have a suggestion please?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
