通过Struts Action调用超链接

Question

我想从Hyperlink导航到JSP页面点击Stucts flow： 从My Jsp Page调用Struts Config文件到超链接：

<a href="userAction.do?page=user">User Creation</a><br />

在Struts-config.xml中： 我将我的动作类映射如下：

<action-mappings>
    <action name="loginForm" path="/login" scope="request" type="com.soc.app.login.action.LoginAction" validate="false" parameter="page">
        <forward name="failure" path="/jsp/index.jsp" />
        <forward name="sessionexpired" path="/jsp/error.jsp" />
        <forward name="success" path="/jsp/home.jsp" redirect="false"/>
     </action>

<action path="/userAction" type="com.soc.app.users.action.userAction" scope="request" parameter="page" validate="false">
        <forward name="user" path="user"/>
</action>

userAction类：

public userAction()
{
    System.out.println("inside userAction !!!!!!!!!!!!!!");
    logger = Logger.getLogger("AdminLog");
    relativeURL="http://localhost:8080/xyz/";

}   

public ActionForward user(ActionMapping mapping,
        ActionForm form,
        HttpServletRequest request,
        HttpServletResponse response)
        throws Exception {
    System.out.println("inside UserAction");
    HttpSession session = (HttpSession)request.getSession();
    String url = "";
    LinkedHashMap<String,String> links = (LinkedHashMap<String,String>)session.getAttribute("links");


    String requestURL= request.getRequestURL().substring(request.getRequestURL().lastIndexOf("/")+1) ;
    System.out.println("Link value in admin acton requestURL!!!!!!!!!"+requestURL);
    if(request.getQueryString()!=null && !("").equals(request.getQueryString())){
        url = relativeURL+requestURL+"?"+request.getQueryString();
    }else{
        url = relativeURL+requestURL+"?"+request.getQueryString();
    }

    System.out.println("url :  "+url);
    if(links!=null && links.get("user")== null ){
        links.put("user",url);
        //session.setAttribute("links", links);
    }
    return mapping.findForward("user");
}

我可以登录，LoginAction工作正常，但如果我点击超链接，它会显示：

“HTTP状态500 - 无法创建路径/ userAction的操作实例”
