Forms Java Bean and image quality - the final consecration

After a long research, I finally managed to get it !

In its third version, this Java Bean does not need any extra JDBC connexion to handle images from/to the database, but a single PL/SQL database package.

Thanks Great Blog. I can now get the file w/o the second bean but it will not display the image. I am testing using client sever and I receive this error in the Java console: Image found in DOCBASE: file:/C:/temp/Falcheck.jpgException occurred during event dispatching:java.lang.NoClassDefFoundError: javax/imageio/ImageIO at oracle.forms.fd.HandleImage.imageIconToByteArray(HandleImage.java:621) at oracle.forms.fd.HandleImage.setProperty(HandleImage.java:157) at oracle.forms.handler.ComponentItem.setCustomProperty(Unknown Source)

It is clearly indicated in the article that this third version needs the Sun Java Plug-in 1.4, and you are probably trying to use it with the JInitiator.
See the second version that runs with Oracle JInitiator:

Help! I have not been able to use "imagepicker" and "HandleImage" beans on the same form 10g. Either one works or the other does not. I would like to select an image using imagepicker and display it using HandleImage. Any Ideas? Thanks

Read the article you are pointing. It contains a method to display the JFileChooser, so that you do noty have to add any other bean for that:
Varchar2 := Get_Custom_Property( 'BL.BEAN', 1, 'GET_FILE_NAME' )

Dear François,I'm currently using your handleimage3 and it is a nice tool!Just 2 questions:- I would like to change the proposed extensions in the file dialog. Is there a possibility through a bean property or should I edit the bean in JDeveloper?- I'm also using webutil in other forms. The problem is that I can not control the file dialog style, as I can with your bean (system vs. java) ...  it apper to be a 'random behaviour'. Do you have any tips? Or is there a bean similar to your, but without image preview?Thanks a lot in advance.Boris

Boris,
There is no way to change the extension for the single reason that the Bean only reads .gif and .jpeg files.
For the second question, you can write a very simple Java Bean that calls a JFileChooser() and set the Look and Feel:
    try
    {
      UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
      SwingUtilities.updateComponentTreeUI(this);
    }
    catch (Exception ex)
    {
      ex.printStackTrace();
    }
