Myeclipse 8.5部署Struts 1.2 struts-config.xml文件经常出错？

XML code

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN" "http://struts.apache.org/dtds/struts-config_1_2.dtd">

<struts-config>
  <data-sources />
  <form-beans >
    <form-bean name="userForm" type="com.yourcompany.struts.form.UserForm" />

  </form-beans>

  <global-exceptions />
  <global-forwards />
  <action-mappings >
    <action
      attribute="userForm"
      input="/form/user.jsp"
      name="userForm"
      path="/user"
      scope="request"
      type="com.yourcompany.struts.action.UserAction">
      <forward name="succes" path="/succes.jsp" />
      <set-property property="cancellable" value="true" />
    </action>

  </action-mappings>

  <message-resources parameter="com.yourcompany.struts.ApplicationResources" />
</struts-config>

就是这一行: type="com.yourcompany.struts.action.UserAction">每建一个项目这里都会报错：
用的是Tomcat 6.x
错误信息是:
