How can I get the icon to display for a file from a Java app?

Is it possible from a Java desktop app to find the icon to display for a given file, perhaps based on it's mime type? Specifically I want to ask the host OS for the icon to display so it can match what the user would expect to see.

There is some example here. The relevant code would be:

FileSystemView view = FileSystemView.getFileSystemView();    
Icon icon = view.getSystemIcon(file);

Edit (included comment) The official help page is here.

AS far as I know the only thing you can do is using the JTree's DefaultTreeCellRenderer. You can read more in the Java API.

I'll give you a few examples here. I haven't used it in a while so you will need to dig a little deeper to get what you want.

UIDefaults defaults = UIManager.getDefaults( );

Icon computerIcon = defaults.getIcon( "FileView.computerIcon" );
Icon floppyIcon   = defaults.getIcon( "FileView.floppyDriveIcon" );
Icon diskIcon     = defaults.getIcon( "FileView.hardDriveIcon" );
Icon fileIcon     = defaults.getIcon( "FileView.fileIcon" );
Icon folderIcon   = defaults.getIcon( "FileView.directoryIcon" );
