    <p>I am currently building an application, where I want a whole directory to be imported in another one. I am working with apache commons.io library that you need to import a s a jar file.</p> <p>Let's say from a directory that I will choose with a JfileChooser from GuiBuilder Netbeans into C:\output. I want all the images to be imported there. My code is not running. When I am pressing JButton2 ( the button responsible for loading a directory I get an exception </p> <blockquote> <blockquote> <p>Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException at WebAppImg.jButton2ActionPerformed(WebAppImg.java:141) ( The second line points out to : String filename = f.getAbsolutePath(); )</p> </blockquote> </blockquote> <p>copyDirectoryToDirectory method maybe. But my thoughts on doing that was that when putting FileSelectionMode to be Directories_Only that the absolute path would be something like C:\importFile and not C:\importFile\image1.jpg for example so it would not be wrong. But maybe this is the mistake?</p> <p>So far, this is my code.</p> <pre><code> private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) { // TODO add your handling code here:(for importing a whole directory(folder) from C:\images1 into C:\output ). JFileChooser chooser = new JFileChooser(); chooser = new JFileChooser(); //chooser.setCurrentDirectory(new java.io.File(".")); //chooser.setDialogTitle(choosertitle); chooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY); //chooser.showOpenDialog(null); //chooser.setAcceptAllFileFilterUsed(false); File f = chooser.getSelectedFile(); String filename = f.getAbsolutePath(); try { File srcDir = new File(filename); File destDir = new File("C:/output/"); FileUtils.copyDirectoryToDirectory(srcDir, destDir); } catch (Exception ex) { ex.printStackTrace(); } } </code></pre>

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.
