警告: [SetPropertiesRule]{Server/Service/Engine/Host/Context} Setting property 'so

Tomcat启动时提示：

2010-9-16 10:38:03 org.apache.tomcat.util.digester.SetPropertiesRule begin
警告: [SetPropertiesRule]{Server/Service/Engine/Host/Context} Setting property 'source' to 'org.eclipse.jst.j2ee.server:strut2demo' did not find a matching property.

[SetPropertiesRule]警告的原因是Tomcat6.0的server.xml的context节点中不支持source属性，详细可以访问tomcat.apache.org，具体相关内容是：

For Tomcat 6, unlike Tomcat 4.x, it is NOT recommended to place <Context> elements directly in the server.xml file. This is because it makes modifying the Context configuration more invasive since the main conf/server.xml file cannot be reloaded without restarting Tomcat.

通关官网文档就可以轻松找到解决办法了。

这里通过修改Tomcat server配置（使用的是eclipse）。关闭server，然后在server视图中双击server，打开配置界面，选中下面的”Publish module contexts to separate XML files”，保存退出。
