Answer 1

If it's 4.6 RIM OS, why don't you use Border:

BasicEditField roundedBorderEdit = new BasicEditField();
XYEdges padding = new XYEdges(15, 15, 15, 15);
int color = Color.CRIMSON;
int lineStyle = Border.STYLE_DOTTED;
Border roundedBorder = BorderFactory.createRoundedBorder(padding, 
     color, lineStyle);
roundedBorderEdit.setBorder(roundedBorder);

BasicEditField bevelBorderEdit = new BasicEditField();
XYEdges edges = new XYEdges(10, 10, 10, 10);
XYEdges outerColors = new XYEdges(Color.BLACK, Color.WHITE, 
     Color.BLACK, Color.WHITE);
XYEdges innerColors = new XYEdges(Color.WHITE, Color.BLACK, 
     Color.WHITE, Color.BLACK);
Border bevelBorder = BorderFactory.createBevelBorder(edges, 
     outerColors, innerColors);
bevelBorderEdit.setBorder(bevelBorder);

If your BlackBerry OS version 4.5 and older, you may try draw bitmap with border on it, on paint event:

class BorderedEdit extends BasicEditField
{
    Bitmap mBorder = null;

    public BorderedEdit(Bitmap borderBitmap) {
        mBorder = borderBitmap;
    }

    protected void paint(Graphics graphics) {
        graphics.drawBitmap(0, 0, mBorder.getWidth(), 
            mBorder.getHeight(), mBorder, 0, 0);
        super.paint(graphics);
    }
}

override paint method as follows:

editField= new BasicEditField(..parameters here..) {
            public void paint(Graphics g) {
                super.paint(g);
                g.drawRect(0, 0, getWidth(), getHeight());
            }
        };
