You did something wrong the way you are accessing the bean "LoginForm" in your JSP page. Please post the JSP.

Or you somehow, missed to create the bean or didn't placed it any scope before forwarding request to the JSP.

No need to take the "name" attribute in Struts text tag, especially when you are taking input from the user. Remove them.

You're using Struts html form tags without a Struts html form; please show the Struts configuration for this action.

Accessing a JSP with Struts tags on it without going through the Struts request handling process will not work.
