NetBeans报错

我在学习ajax4jsf配置的时候，忘记在web.xml里配置ajax4jsf了，结果tomcat启动运行后，报错如下：

2008-11-7 15:41:43 org.apache.catalina.core.StandardWrapperValve invoke

可是我修改web.xml后，netbeans里运行程序，tomcat启动日志里还是报错，错误和上面的一样，还是说web.xml配置有问题，但是程序运行没有错误。显然这个是tomcat误报。那么是甚么原因造成误报呢？经过整整1天的查找，发现是tomcat的日志问题。原来，在netbeans里运行程序，tomcat把日志保存在“C:/Documents and Settings/系统登录用户/.netbeans/6.1/apache-tomcat-6.0.16_base/logs”下，localhost.yyyy-MM-dd（yyyy-MM-dd为当天日期），tomcat运行的错误都保存在这里，如果第一次有有错误日志写在这里，以后在netbeans里运行项目，都会把这里的日志显示在netbeans的输出窗口的tomcat的日志里。找到地方后，就好办了，删除这里的日志，重新运行项目，一切ok，就不会再报错了。
