我的struts-config.xml有什么问题吗？求答

<?xml version="1.0" encoding="UTF-8"?>
<struts-config>
   <data-sources />
   <form-beans >
     <form-bean name="loginForm" type="com/leadtone/web/struts/form/LoginForm" />
   </form-beans>
   <global-exceptions />
   <global-forwards />
   <action-mappings >
     <action
       attribute="loginAction"
       input="/login.jsp"
           name="loginAction"
       path="/login"
       scope="request"
           type="org.springframework.web.struts.DelegatingActionProxy">
        <forward name="failure" path="/failure.jsp" />
    <forward name="success" path="/succ.jsp" />
    </action>
    </action-mappings>
  <controller processorClass="org.springframework.web.struts.DelegatingRequestProcessor"></controller>
      <message-resources parameter="com.leadtone.web.struts.ApplicationResources" />
  <plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
    <set-property property="contextConfigLocation" value="classpath:applicationContext.xml" />
  </plug-in>
</struts-config>
