在eclipse GANYMEDE中apache-tomcat-6.0.16加载工程后，启动服务器就会出现如下的红色警告信息，真是让人不爽：
2008-10-11 21:33:55 org.apache.tomcat.util.digester.SetPropertiesRule begin
警告: [SetPropertiesRule]{Server/Service/Engine/Host/Context} Setting property ‘source’ to ‘org.eclipse.jst.jee.server:TestTomcat6.0.16’ did not find a matching property.
2008-10-11 21:33:55 org.apache.catalina.core.AprLifecycleListener init

在网上查找答案，有的说将Tomcat的版本换成6.0.14就可以了；还有的说在建立Dynamic Web Project时把”Dynamic Web Module”选项后面的版本号由2.5改成2.4也行。不过这些回答好像都不能真正地解决问题。
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=”/…” source=”org.eclipse.jst.j2ee.server:…”/>
解决方法是在Servers视图里双击创建的server，然后在其server的配置界面中选中”Publish module contexts to separate XML files”选项。
不过”Publish module contexts to separate XML files”究竟是什么意思，有必要看下”Tomcat Publishing Options”。
