Java 无法加载属性

您好，我打算用java（NetBeans）开发web服务，但是get Conconnect有问题，我遇到以下错误：

我有config.properties，其中是URL和Context.xml。这个文件处理从文件config.properties检索属性，还有log4j.xml/dtd，它们都在我的类路径中

这是我的con Context.xml

真的

有什么建议吗？？？谢谢你的建议：

<property name="location" value="file://C:\\Users\\gerardo.granados\\Documents\\APITest\\build\\classes\\config.properties"/>

这在一个相关问题中对我起了作用。

在配置的某个点上，您试图连接到一台您标识为

C

的机器，这可以通过-->

java.net.UnknownHostException:C

<property name="location" value="file:C:\\Users\\gerardo.granados\\Documents\\APITest\\build\\classes\\config.properties"/>
