What is the problem when opening jpg files using Desktop API

Question

Hi, i would like to open jpg, or gif files using Desktop API, and the application crashes.The Desktop API is supported by my OS, because txt files, or file directories can be opened, mails can be sent, browsing is also supported.
Only jpg and gif, and i think other picture formats cannot be opened.
Obviously ACDSee and other picture viewing programs are installed in my computer.
The corresponding application code can be found at the bottom of the page of http://www.awprofessional.com/articles/article.asp?p=661371&seqNum=2&rl=1
my code:
if(Desktop.isDesktopSupported()){
Desktop desktop=Desktop.getDesktop();
try
desktop.open (fileToOpen);
catch (IOException ioe)
JOptionPane.showMessageDialog (frame,
"I/O problem");
catch (IllegalArgumentException iae)
JOptionPane.showMessageDialog (frame,
"File doesn�t exist");
fileToOpen is obviously a File.
Thx for the help in advance.

Answer 1

My file association for jpg files is correct, if i click on a
jpg, ACDSee starts immediately.Although I am a long time Windoze non-user, I vaguely remember that there's a difference between correct file-type association being set and some application starting at a mouse click on a file icon. I also vaguely remember Windoze file-type association mechanism uses a few action-types. Java Desktop should expect a specific action-type for the association.
