Setting a JPanel alignment

Question

hi all,
I'm using a BorderLayout for my simply application.
I have created a JPanel that contains two buttons, as follows:
JPanel pannello_pulsanti=new JPanel();
pannello_pulsanti.setLayout(new BoxLayout(pannello_pulsanti, BoxLayout.LINE_AXIS));
salva.setPreferredSize(new Dimension(100, 20));
salva.setMaximumSize(new Dimension(100, 20));
reset.setPreferredSize(new Dimension(100, 20));
reset.setMaximumSize(new Dimension(100, 20));
pannello_pulsanti.add(salva);
pannello_pulsanti.add(Box.createRigidArea(new Dimension(0, 5)));
pannello_pulsanti.add(reset);I had in mind to put the JPanel inside the "PAGE_END" location, and I did it.
the problem is that the panel has a left alignment, while I want a center alignment for it (I tried to change its alignment with setAlignmentX method, but it doesn't work).
can anyone help me in solving this problem?
thanks,
varying
