BoxLayout: components with different alignmentX

Question

Hi all. Java newbie here.. Here's what I'm trying to do: Use BoxLayout to "left-align" three components, and have one component at the bottom centered at its container/frame.
Something like this:
| ( One )        |
| ( Two )        |
| ( Three )      |
|     ( Four )   |
`----------------'I want the Fourth component to be exactly in the center of the frame, and the others to be left-aligned to the frame. Here's the code:
JButton b1 = new JButton("One");
JButton b2 = new JButton("Two");
JButton b3 = new JButton("Three");
JButton b4 = new JButton("Four");
b1.setAlignmentX(Component.LEFT_ALIGNMENT);
b2.setAlignmentX(Component.LEFT_ALIGNMENT);
b3.setAlignmentX(Component.LEFT_ALIGNMENT);
b4.setAlignmentX(Component.CENTER_ALIGNMENT);
// Add them all to container with BoxLayout.PAGE_AXISAccording to Sun's tutorial, fixing alignment problems can be done by setAlignmentX. Obviously, I didn't understand their documentation because the buttons come out differently.
Any fix for this? Thanks for the help in advance.

Just a quick note :
In the doco for it says :
setAlignmentX - sets the vertical alignment
setAlignmentY - sets the horizontal alignment
I think you want Y and not X
I do want X because Y refers to TOP/CENTER/BOTTOM_ALIGNMENT, and I'm looking for LEFT/RIGHT/CENTER_ALIGNMENT. It is in the "Fixing Alignment Problems" (http://java.sun.com/docs/books/tutorial/uiswing/layout/box.html#align).
