ADDITIONAL OS VERSION INFORMATION :

EXTRA RELEVANT SYSTEM CONFIGURATION :
Installed adobe reader from the multiverse extra repository,
right-clicked on a PDF file and told it to open all PDF files with adobe reader

A DESCRIPTION OF THE PROBLEM :
Ubuntu 8.10 out of the box uses document viewer 2.24.1 to open PDF files.
I added the multiverse ubuntu repo,
apt-get installed acroread,
and configured PDF files to open with that adobe reader.
Yet Desktop.getDesktop().open("myPdf.pdf") still opens it with the document viewer.

Thunderbird etc use the correct program for opening a pdf file: adobe reader.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
see description

EXPECTED VERSUS ACTUAL BEHAVIOR :
