import com.test.model.Point;

public class PointConverter2 extends StrutsTypeConverter {

	@Override
	public Object convertFromString(Map arg0, String[] arg1, Class arg2) {
		
		Point point = new Point();
		
		String[] params = arg1[0].split(",");
		
		int x = Integer.valueOf(params[0]);
		int y = Integer.valueOf(params[1]);
		
		point.setX(x);
		point.setY(y);
		
		return point;
	}

	@Override
	public String convertToString(Map arg0, Object arg1) {
		
		Point point = (Point)arg1;
		
		StringBuffer info = new StringBuffer();
		
		info.append("[ ").append(point.getX()).append(" , ").append(point.getY()).append(" ]");
