I have 2 pages here, in first page i am accepting inputs and then displaying it on seconds page by validating input data using java class user.

    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>

<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>

<form action="/myweb/formbean.jsp" method="post">

Username : <input type="text" name="name" placeholder="name"><br>

JAVA USER CLASS

public class user {

    private String name;
    private String password;
    private String message;

    public user() {

        validate();
    }

    public user(String name, String password) {

        this.name = name;
        this.password = password;
        validate();
    }

    public void setMessage(String message) {
        this.message = message;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getPassword() {
        return password;
    }

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

    public String getMessage() {
        return message;
    }



    public void validate() {

        if (name == null) {
            message = "name cannot be null";

        } else if (password == null) {
            message = "passowrd cannot be null";

        }
        message="form validatuion ok";

    }

}

When i submit the form parameter message value never gets updated it always show me message "name cannot be null" Not sure what i am doing wrong here, please help me figure it out.
