    <p>Here's some untested code base on some old code I had that unzipped files.</p> <pre><code>public void doUnzip(String inputZip, String destinationDirectory) throws IOException { int BUFFER = 2048; List zipFiles = new ArrayList(); File sourceZipFile = new File(inputZip); File unzipDestinationDirectory = new File(destinationDirectory); unzipDestinationDirectory.mkdir(); ZipFile zipFile; // Open Zip file for reading zipFile = new ZipFile(sourceZipFile, ZipFile.OPEN_READ); // Create an enumeration of the entries in the zip file Enumeration zipFileEntries = zipFile.entries(); // Process each entry while (zipFileEntries.hasMoreElements()) { // grab a zip file entry ZipEntry entry = (ZipEntry) zipFileEntries.nextElement(); String currentEntry = entry.getName(); File destFile = new File(unzipDestinationDirectory, currentEntry); destFile = new File(unzipDestinationDirectory, destFile.getName()); if (currentEntry.endsWith(".zip")) { zipFiles.add(destFile.getAbsolutePath()); } // grab file's parent directory structure File destinationParent = destFile.getParentFile(); // create the parent directory structure if needed destinationParent.mkdirs(); try { // extract file if not a directory if (!entry.isDirectory()) { BufferedInputStream is = new BufferedInputStream(zipFile.getInputStream(entry)); int currentByte; // establish buffer for writing file byte data[] = new byte[BUFFER]; // write the current file to disk FileOutputStream fos = new FileOutputStream(destFile); BufferedOutputStream dest = new BufferedOutputStream(fos, BUFFER); // read and write until last byte is encountered while ((currentByte = is.read(data, 0, BUFFER)) != -1) { dest.write(data, 0, currentByte); } dest.flush(); dest.close(); is.close(); } } catch (IOException ioe) { ioe.printStackTrace(); } } zipFile.close(); for (Iterator iter = zipFiles.iterator(); iter.hasNext();) { String zipName = (String)iter.next(); doUnzip( zipName, destinationDirectory + File.separatorChar + zipName.substring(0,zipName.lastIndexOf(".zip")) ); } } </code></pre>

    1. COWhy do you have a throws declaration, and yet actually catch the exception and log it? Doesn't that mean callers will be expecting IOExceptions that never get thrown..?

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.
