百度地图API 折线问题

我将一连串的BMap.Point类型的对象放入了paths这个数组中，希望在地图上可以将数组中的一连串的坐标点显示为一条线，如下是不能，求解
var polyline = new BMap.Polyline(
paths,
{strokeColor:"blue", strokeWeight:6, strokeOpacity:0.5}
);
map.addOverlay(polyline);
）

<script type="text/javascript">
var maplet = null;
function initMap(){
maplet = new Maplet("mapbar");
maplet.centerAndZoom(new MPoint(116.38749,39.90515), 8);
maplet.addControl(new MStandardControl());

var polyline = new MPolyline(
[
new MPoint(116.33217,39.94761),
new MPoint(116.33217,39.9429),
new MPoint(116.33217,39.87544),
new MPoint(116.33217,39.86687)
],
new MBrush(),
new MInfoWindow("信息窗口标题", "信息窗口内容")
);

maplet.addOverlay(polyline);

polyline.setEditable(true);

MEvent.addListener(maplet, "edit", editEnd);
}

function editEnd(overlay) {

overlay.setEditable(false);

var msg = "";
for(var i=0; i<overlay.pts.length; i++)
msg += overlay.pts[i].getPid() + ";";

alert("折线对象点集合：\n" + msg.substring(0,msg.length-1));
}
</script>
