我用的eclipse Helios，tomcat 7
每次重启server的时候，都会给出警告
警告: [SetContextPropertiesRule]{Context} Setting property 'source' to 'org.eclipse.jst.jee.server:str' did not find a matching property.
2011-4-12 4:08:10 org.apache.tomcat.util.digester.SetPropertiesRule begin
警告: [SetPropertiesRule]{Context/Loader} Setting property 'useSystemClassLoaderAsParent' to 'false' did not find a matching property.
按照网上查找的办法，把：
public module contexts to separate xml files和
Serve module without publishing
都选上了，还是提示这个错误，怎么解决呢
