解决tomcat启动产生[SetPropertiesRule]警告问题(转载)

[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。
