Java Can'；t在JSP中实现简单的自定义图标谷歌地图示例

当我尝试在Jetty服务器上用jsp实现以下简单示例时：我得到一个java.io.UTFDataFormatException，并且地图上没有显示任何图标 产生错误的代码段是：

var image='images/beachflag.png'；
var mylatng=new google.maps.LatLng（-33.890542151.274856）；
var beachMarker=new google.maps.Marker({
职位：myLatLng，
地图：地图，
图标：图像
});

如果我像下面那样注释掉标记的图标变量，那么一切都正常

var image='images/beachflag.png'；
var mylatng=new google.maps.LatLng（-33.890542151.274856）；
var beachMarker=new google.maps.Marker({
职位：myLatLng，
地图：地图
});

当然，标准的谷歌标记会显示出来，而不是我想要的自定义图标

这是我使用jetty maven插件9.2.10.v20150310的stacktrace：

提前感谢您的指点

编辑：更改了最新jetty server 9.2.10生成的stacktrace。v20150310

您必须修改图像路径或将图标上载到自己的服务器

如果看不到标记，则可能找不到图像

它们使用相对URL

“images/beachflag.png”

，在示例中指向：

https://google-developers.appspot.com/maps/documentation/javascript/examples/full/images/beachflag.png 

---

函数初始化（）{
var mylatng=new google.maps.LatLng（-33.890542151.274856）；
var map=new google.maps.map（document.getElementById（“地图画布”）{
中心：myLatLng，
缩放：10
});
var图像处理https://google-developers.appspot.com/maps/documentation/javascript/examples/full/images/beachflag.png';
var beachMarker=new google.maps.Marker({
职位：myLatLng，
地图：地图，
图标：图像
});
}
google.maps.event.addDomListener（窗口“加载”，初始化）
html{
身高：100%
}
身体{
身高：100%；
保证金：0；
填充：0
}
#地图画布{
身高：100%
}

谢谢。我将其更改为最新的稳定版本，仍然存在相同的问题。虽然stacktrace有点变化，但我已经更新了。谢谢。虽然我已经确定可以找到图像，但它在我的服务器上。例如，当我更改文件名以便找不到图像时，没有长时间的异常。但我得到了以下短错误：
