使图像可以通过URL在Tomcat

Question

我跟着这个SO并按照上述方法添加到我的server.xml一个Context tag：

...   
    <Context docBase="evappserver" path="/" reloadable="true" source="org.eclipse.jst.jee.server:evappserver"/> 
    <Context docBase="/Users/vladioffe/Development/uploded_events" path="/image" /> 
    </Host> 

但是，当我尝试访问一些图像，我有这个文件夹像这样：

http://localhost:8080/image/jNzifRYFuOSBJYAVPFaqhIXbDxjPQgIS.png 

我得到404错误。

这里是我的server.xml：

任何一个可以建议如何解决这一问题？谢谢！

你的配置没问题，试着检查你的路径和对图片文件夹的访问权限是否正确，然后重新启动tomcat。
