jsp - s:url link returns 404 "The requested resource is not available" -


when click on link, placed in login.jsp, error "the requested resource not available."

<s:url id="register_url" action="registerlink" /> <s:a href="%{register_url}"> register </s:a>

login.jsp 

<%@ page language="java" contenttype="text/html; charset=utf-8"%> <%@ taglib prefix="s" uri="/struts-tags"%> <!doctype html "> <html>     <head>         <title>biblioteka</title>     </head>     <body>          <s:url id="register_url" action="registerlink" />          <s:a href="%{register_url}"> register </s:a>          <div class="login-div">             <s:actionerror escape="false" />             <s:actionmessage escape="false" />             <s:form action="login" method="post">                 <s:textfield name="memberbean.email" label="e-mail" />                 <s:password name="memberbean.password" label="fjalëkalimi" />                 <s:submit value="dërgo" />             </s:form>         </div>     </body> </html>

also, if place s:url tag inside home.jsp, links perfectly.

the id attribute deprecated. use var instead. use namespace attribute if have namespace in package. reference context variable #. don't use underscore variable name.

<s:url var="registerurl" namespace="/" action="registerlink" /> <s:a href="%{#registerurl}">register</s:a>
