初学struts，配置web.xml后，tomcate无法正常启动。急求高手
以下是我的struts-config.xml文件：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts 
Configuration 1.1//EN" "http://struts.apache.org/dtds/struts-config_1_1.dtd">

<struts-config>
<form-beans>
<form-bean name="helloWordActionForm" type="com.file.HelloWorldActionForm"/>

</form-beans>

<action-mappings>
<action path="/HelloWorldAction" type="com.file.HelloWorldAction"
name="helloWorldActionForm"
parameter="methode"
scope="request" validate="false">
<forward name="success" path="/WhoSayHelloWorld.jsp"/>
</action>
</action-mappings>



</struts-config>



以下为web.xml文件：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.5//EN"
