解决tomcat启动产生[SetPropertiesRule]警告问题

[SetPropertiesRule]{Server/Service/Engine/Host/Context} Setting property 'source' to 'org.eclipse.jst.j2ee.server:*' did not find a matching property.

出现SetPropertiesRule警告的原因是因为Tomcat在server.xml的Context节点中不支持source属性

<Context docBase="..." path="/cont" source="org.eclipse.jst.j2ee.server:*"/>

解决方法是在Server的配置界面中选中"Publish module contexts to separate XML files"选项。
