tomcat配置時的警告（did not find a matching property)和 Setting property 'source' to 'org.eclipse.jst.jee.se
用了一段時間的tomcat後，發現今天居然報警告，did not find a matching property還有Setting property 'source' to 'org.eclipse.jst.jee.se等一串，根據度娘上大神的解答，如下：
Server's Properties -> General -> Location = /Servers/Tomcat v6.0 Server at localhost.server;
Project Explorer -> Servers -> Tomcat v6.0 Server at localhost.server, double click to open it.
Server Options -> Check "Publish module contexts to separate XML files ".
Explaination :
Tomcat of previous version doesn't support the "source" attribute in the "Context" node of "server.xml" file.
Result :
A separate XML file named "demo.xml" was created in the "$server path$\conf\Catalina\localhost\".
也就是關閉tomcat，雙擊eclipse下tomcat伺服器，在出來的Tomcat server at localhost頁面中找到server options選項，選中其中的選項”Publish modual contexts to separat XML files“，ctr+s，啟動tomcat，但是發現tomcat7這樣做並沒有效果，於是乎就找配置檔案，更改配置檔案，弄好就ok了，具體步驟如下：
先修改初始化配置檔案即可：
[tomcat install path]\conf\Catalina\localhost\[customized project].xml
刪除該xml文件中的source="org.eclipse.jst.jee.server:dynweb-test"即可編譯通過。
如果同時還碰到錯誤
WARNING: [SetPropertiesRule]{Context/Loader} Setting property 'useSystemClassLoaderAsParent' to 'false' did not find a matching property.
同樣刪除該xml文件中的useSystemClassLoaderAsParent="false"即可編譯通過。
PS：這個配置檔該是eclips預設生成的，所以似乎每次重啟project後，這個配置文件都會被重置，被刪除的內容會又出現了。需要再次手動刪除。
