I'm getting an error i.e
WARNING: Could not find token mapped to token name token
I didn't understand please tell me why I'm getting this error and how to resolve it.
struts.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC

    <package name="interceptorExecAndWait" extends="struts-default">
        <action name="execAndWaitInterceptor" class="com.interceptor.execandwait.action.ExecuteAndWait">
            <!-- <interceptor-ref name="defaultStack"/>  -->
            <interceptor-ref name="completeStack"/>
                    <interceptor-ref name="execAndWait">    
                                    <param name="delay">1000</param>    
                    </interceptor-ref>  
            <!-- <interceptor-ref name="execAndWait"/> -->
            <result name="success">/welcome.jsp</result>
            <result name = "wait">/wait.jsp </result>
            <result name="error">/error.jsp</result>
        </action>
    </package>
</struts>

ExecuteAndWait.java

public class ExecuteAndWait {

    String userName;
    String password;

    public String execute() throws InterruptedException {

        if (userName.equals("Admin") && password.equals("user")) {
            System.out.println("ok");
            Thread.sleep(5000);
            return "success";
        } else {
            return "error";
        }
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }


}

Let me know where I make mistakes
Thanks :)

You don't show your refresh meta tag, but it's likely it doesn't include the includeParams="all" in the <s:url> tag, e.g.,

<head>
  <title>Please wait</title>
  <meta http-equiv="refresh" content="5;url=<s:url includeParams="all" />"/>
</head>

Add

<interceptor-ref name="completeStack"/>
              <interceptor-ref name="execAndWait">
                <param name="delay">1000</param>
                <param name="delaySleepInterval">500</param>
            </interceptor-ref>

in your struts.xml i.e.,

<package name="interceptorExecAndWait" extends="struts-default">
        <action name="execAndWaitInterceptor" class="com.interceptor.execandwait.action.ExecuteAndWait">
              <interceptor-ref name="completeStack"/>
              <interceptor-ref name="execAndWait">
                <param name="delay">1000</param>
                <param name="delaySleepInterval">500</param>
            </interceptor-ref>
            <result name="success">/welcome.jsp</result>
            <result name = "wait">/wait.jsp </result>
            <result name="error">/error.jsp</result>
        </action>
    </package>

Include the includeParams="all" and http-equiv="Refresh" in the meta tag, in your wait.jsp i.e.,

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<%@ taglib uri="/struts-tags" prefix="s"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Refresh" content="5;url=<s:url includeParams="all" />">
<title>Waiting</title>
</head>
<body>

    <div align="center">
        <h2>Please wait while we verify your credentials.. </h2>
    </div>

</body>
</html>
