Tomcat 阀门 - java.lang.NoSuchMethodError

Question

Tomcat 6.0.36

启动 tomcat 时出现 java.lang.NoSuchMethodError。

我的 server.xml 中有这个:

<Host name="dev.spirit.comp.net" appBase="spirit"
                unpackWARs="true" autoDeploy="true" xmlValidation="false"
                xmlNamespaceAware="false">
                <Alias>dev.spirit.comp.com</Alias>  
                <Valve className="org.apache.catalina.valves.ImprovedAccessLogValve"
                directory="logs/spirit" prefix="${hostname}-${port}.access_log."
                suffix=".txt"
                pattern="%h %v %u %t '%r' %s %b '%{Referer}i' '%{User-Agent}i' '%{Cookie}i'"
                resolveHosts="false" fileDateFormat="yyyy-MM-dd.HH" />

我收到这个错误:

发现问题，不知为何tomcat服务器中有一些来自其他版本的jar文件
