Java HotSpot Virtual Machine

I'm using eclipse package to display a simple DirectoryChooser, and when ever I try to run my jar file I have the following message
Exception in thread "main" java.lang.UnsatisfiedLinkError: no swt-win32-3232 in java.library.path ....etc
the code is very simple when I click a button the following code must executed

public void actionPerformed(java.awt.event.ActionEvent e) {
                    Display display = new Display();
                    final Shell shell = new Shell(display);

                    DirectoryDialog dlg = new DirectoryDialog(shell);
                    String selectedDirectory = dlg.open();
                    System.out.println(selectedDirectory);
                    display.dispose();
                }

I created a manifest file as well:

Manifest-Version: 1.0
Main-Class: com.tests.DirectoryDialogGetSelectedDirectory
Class-Path: org.eclipse.swt.win32.win32.x86_3.2.0.v3232m.jar

I put the generated jar (sample.jar) file and org.eclipse.swt.win32.win32.x86_3.2.0.v3232m.jar in the same folder and and when I run sample.jar and click the button I have

Exception in thread "AWT-EventQueue-0" java.lang.UnsatisfiedLinkError: no swt-win32-3232 in java.library.path
