Hi Friends

Did someone succeed to implement the get_file_name built-in of forms using a javabean with the wrapper class as suggested by Oracle at Metalink (Note:74140.1) ?

When I try to compile it, I've got the following error :

                        MyDialog.java:4: Public class FDialog must be defined in a file called "FDialog.java".

			  public class FDialog extends Canvas  {
			               ^
			1 error

The java source that I tried to compile is given here below :

PURPOSE

---

The get_file_name built-in of forms is currently not implemented for Web. You could create a Javabean and use it to implement this functionality for WebForms.

Attached below are the source code of JavaBean & the Wrapper Class for the Bean.

CREATING JAVABEAN

---

The Bean uses the following methods and Classes

---

PropertyChangeSupport for the file_name property.

java.awt.FileDialog class is used to show the File Dialog.

firePropertyChange method is called to pass a PropertyChange event to all classes which are registered as listeners to this class.

addPropertyChangeListener is used by other classes to register themself as PropertyChangeListener for this class.

import java.awt.*;
import java.beans.*;  

  public class FDialog extends Canvas {   private String file_name ;
  private PropertyChangeSupport pcs;

public FDialog() {
  file_name = "";
  pcs = new PropertyChangeSupport(this);
}

  public void set_file_name()
  {
  Frame frame = new Frame("Sample");
  java.awt.FileDialog OpenDlg = new FileDialog(frame, "Open ", java.awt.FileDialog.LOAD);
  OpenDlg.setFile("*.*");
  OpenDlg.show();
  String old_file_name = file_name;
  file_name=OpenDlg.getDirectory() + OpenDlg.getFile();   pcs.firePropertyChange("file_name", old_file_name, file_name);
}

  public void addPropertyChangeListener(PropertyChangeListener pcl)   {
  pcs.addPropertyChangeListener(pcl);
}

  public void removePropertyChangeListener(PropertyChangeListener pcl)   {
  pcs.removePropertyChangeListener(pcl);
}
}
