JList does not show selected value

I have a program where I use a username and password to get into a database.  When I log in, I have a JList added to a scroll pane.  In that JList I have list of all the users.  I would like it to select automatically the name of the user who is logged in and scroll down to that name.  I used
jlist.setSelectedValue(username, true), but it just selects the name but does not scroll down to it.  I did not use Viewport for this scrollpane.  Any advice?

even with this line
list.ensureIndexIsVisible( list.getSelectedIndex() );
comented it works like you wish.

call ebsureIndexIsVisible() method in JList. That will do the trick.

list.setSelectedValue(...);
                      list.ensureIndexIsVisible( list.getSelectedIndex() );

I tried to use that command, but it did not work, because I use DefaultListModel, not Viewport; and that command works only with Viewport.

OVIDIU, when I ran this program, the problem was still there... The selected value was 999, but it did not scroll to that number automatically.  The scroll was still showing me the first 25 indecies.

Do you think something is wrong with my system? I even tried the programs from the java's website with the code that has the line, but it still didn't work? Tomorrow I will post my system stats.  But are you sure that the program works fine on your system?

Thanx for trying. I figured out what the problem was. One of the frames was resetting my scrollpane.
