Java SE (Java Platform, Standard Edition)

Hi,
I've found a few posts on this topic, but I cannot seem to figure out how to apply them to my situation. I have a JScrollPane and whenever the text in it exceeds the size of the box the vertical scroll bar appears as expected; however, the pane's default position is always at the bottom of the text. I would like to have the position default to the top of the pane - simple enough right?

Here is the code for the pane:

		// Overview
		JLabel overviewLbl = ActionLabel.getOverviewLabel();
		topGbc.gridx = 0;
		topGbc.gridy = line_count++;
		topGbc.insets = new Insets(0,0,0,0);
		topGbc.anchor = GridBagConstraints.WEST;
		topGbc.gridwidth = 4;
		topGbc.gridheight = 1;
		topGb.setConstraints( overviewLbl, topGbc );
		super.getContentPane().add( overviewLbl );

		overviewTA = new PLTextArea();
		overviewTA.setEditable( false );
		PLScrollPane overviewSP = new PLScrollPane( overviewTA );
		overviewSP.setPreferredSize( new Dimension( 470, 80 ));
		overviewSP.setVerticalScrollBarPolicy( PLScrollPane.VERTICAL_SCROLLBAR_ALWAYS );
		overviewSP.getViewport().setViewPosition(new Point(0,0));
		topGbc.gridx = 0;
		topGbc.gridy = line_count++;
		topGbc.insets = new Insets( 0,PLDefault.LEFT_INSET,0,0 );
		topGbc.anchor = GridBagConstraints.WEST;
		topGbc.gridwidth = 4;
		topGb.setConstraints( overviewSP, topGbc );
		super.getContentPane().add( overviewSP );

in the code above I have inserted the line

overviewSP.getViewport().setViewPosition(new Point(0,0));

to try to set the default position to the top, and it is not working. I've also tried this line

overviewSP.getVerticalScrollbar().setValue(0);

but it didn't work either.

Here is the code for the PLScrollPane constructor:

public class PLScrollPane extends JScrollPane{

	public PLScrollPane(Component arg0) {
		super(arg0);
		super.setBackground(PLColor.BACKGROUND);
		getViewport().setBackground(PLColor.SCROLLPANE_BACKGROUND);
		getHorizontalScrollBar().setBackground(PLColor.SCROLLBAR_BACKGROUND);
		getHorizontalScrollBar().setForeground(PLColor.SCROLLBAR_FOREGROUND);
		getVerticalScrollBar().setBackground(PLColor.SCROLLBAR_BACKGROUND);
		getVerticalScrollBar().setForeground(PLColor.SCROLLBAR_FOREGROUND);
		setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_ALWAYS);
	}
}

I also tried putting both lines I mentioned above in this constructor, which did not work either. If anyone could point me in the right direction here I'd appreciate it. This seems like it's probably a dumb mistake I'm making, but I cannot figure this one out! Thanks...
