Please follow the following instruction:

1. index.jsp

<ul>
<li><a href="roseindia/requiredFieldValidatorError.action">RequiredFieldValidator Example</a></li>
</ul>

2. struts.xml

<action name="requiredFieldValidatorError">
<result>/pages/chatQuestion/requiredFieldValidatorError.jsp</result>
</action>

<action name="requiredFieldValidatorError1" class="net.roseindia.requiredFieldValidatorAction">
<result name="input">/pages/chatQuestion/requiredFieldValidatorError.jsp</result>
<result name="error">/pages/chatQuestion/requiredFieldValidatorError.jsp</result>
<result name="success">/pages/chatQuestion/requiredFieldValidatorSuccess.jsp</result>
</action>

3. requiredFieldValidatorError.jsp

<%@ taglib prefix="s" uri="/struts-tags"%>

<html>
<head>
<title>RequiredFieldValidator Example!</title>

<link href="<s:url value="/css/main.css"/>" rel="stylesheet"
type="text/css"/>

<s:head theme="ajax" />
<s:actionerror/>

</head>
<body>

<s:form name="validate" action="requiredFieldValidatorError1" method="POST" validate="true">
<s:textfield name="username" label="Username"/>
<s:password name="password" label="Password"/>
<s:submit value="Submit" />

</s:form>

</body>

</html>

4. requiredFieldValidatorSuccess.jsp

<%@ taglib prefix="s" uri="/struts-tags"%>

<html>
<head>
<title>RequiredFieldValidator Example!</title>

<link href="<s:url value="/css/main.css"/>" rel="stylesheet"
type="text/css"/>
</head>
<body>

Username: <s:property value="username" /><br>
Password: <s:property value="password" />

</body>

</html>

Whenever user don't input any data then it displays an error. If you enter username and password then you get your username and password in requiredFieldValidatorSuccess.jsp.
