    <p>I have this code to zip folders, but when I zip large folders (10GB), I got an error with memory. It works fine with folders around 1GB.</p> <p>Probably some memory leak, but where in my code is the leak? How can I fix this?</p> <p>Thanks.</p> <p>This is the error:</p> <pre><code>Exception in thread "main" java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.eclipse.jdt.internal.jarinjarloader.JarRsrcLoader.main(JarRsrcLoader.java:56) Caused by: java.lang.OutOfMemoryError: Java heap space at java.util.Arrays.copyOf(Arrays.java:2882) at java.lang.AbstractStringBuilder.expandCapacity(AbstractStringBuilder.java:100) at java.lang.AbstractStringBuilder.append(AbstractStringBuilder.java:572) at java.lang.StringBuilder.append(StringBuilder.java:203) at java.io.UnixFileSystem.resolve(UnixFileSystem.java:93) at java.io.File.&lt;init&gt;(File.java:207) at java.io.File.listFiles(File.java:1056) at Zipper.addDir(Zipper.java:27) at Zipper.addDir(Zipper.java:32) at Zipper.addDir(Zipper.java:32) at Zipper.addDir(Zipper.java:32) at Zipper.addDir(Zipper.java:32) at Zipper.addDir(Zipper.java:32) at Zipper.addDir(Zipper.java:32) at Zipper.addDir(Zipper.java:32) at Zipper.addDir(Zipper.java:32) at Zipper.zipDir(Zipper.java:17) at Schedule.runBackup(Schedule.java:128) at Machine.runBackup(Machine.java:108) at Person.main(Person.java:51) </code></pre> <p>This is the code:</p> <pre><code>import java.io.File; import java.io.FileInputStream; import java.io.FileOutputStream; import java.io.IOException; import java.util.zip.ZipEntry; import java.util.zip.ZipOutputStream; import javax.swing.JFrame; import javax.swing.JOptionPane; public class Zipper { static void zipDir(String zipFileName, String dir) throws Exception { File dirObj = new File(dir); try { ZipOutputStream out = new ZipOutputStream(new FileOutputStream(zipFileName)); addDir(dirObj, out); out.close(); } catch(Exception e) { JFrame frame = new JFrame(); JOptionPane.showMessageDialog(frame, e.getMessage() + ".

    1. COWhat's your jdk version? The reason I asked is there is a [JIRA](http://bugs.sun.com/bugdatabase/view_bug.do;:YfiG?bug_id=4705373) on it in jdk 1.4.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
