Question : Validation framework not working for login screen

I am really getting frustrated in making the validation framework work for my login screen.

I have done almost all the things correctly but could not figure where i have gone wrong.
Below contain my struts-config.xml file

Below is the content of validation.xml file

<form-validation>
<formset>

<form name="loginForm">
<field property="username" depends="required">
<arg bundle="label" key="label.login.username"/>
</field>
</form>

</formset>

</form-validation>

next is the content of login.jsp page.

It will be great if someone could identify the mistake i have made. Currently when i click login button without entering anything in the username field nothing happens. I currently expect validation error message to be displayed for not entering the username

Question : Validation framework not working for login screen

Answer : Validation framework not working for login screen

I have resolved the issue. There was a invalid <form-bean/> tag in the struts config file.
