Question

Answer 1

+1 A:

Like said; to give you a sensible suggestion you don't give a lot of information.

I would do it like this:

Enter info in database (registration)
Perform the same actions that occure after a user clicked 'login'
Redirect to the same page as you would after a user is logged in

Yes. The problem is that the 'actions that occure after a user clicked 'login'' are controlled by tomcat, not by the application. I would like to avoid using tomcat's internal classes.

After a login, what is created to verify on a page if an user is logged in? Create that with the info from the registration form. The redirect should pass.

Answer 2

A:

Did you find a solution to this?

I have to ideas. Either create a new HttpSession and try and put the user into the session. Or pass the username and password to the login page with HTTP variables and use javascript to auto submit the form.

I dit (at last), but the registration must be included in the login scenario.

Answer 3

A:

Here is a possible solution: the registration must be included in the login procedure.

A link to the registration form is included in the login form, tough the two forms could also share the same page. Here is the code for login.jsp:

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
   "http://www.w3.org/TR/html4/loose.dtd"&gt;

<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>Authentication</title>
    </head>
    <body>
        <h1>Authentication</h1>
        <p>Please enter your username and password below, then click on the
            'Login' button</p>
        <form action="j_security_check" method="POST">
            <dl>
                <dt><label for="j_username">Username: </label></dt>
                <dd><input type="text" id="j_username" name="j_username"></dd>
                <dt><label for="j_password">Password: </label></dt>
                <dd><input type="password" id="j_password" name="j_password"></dd>
                <dd><input type="submit" name="login" value="Login"></dd>
            </dl>
        </form>
        <p>If you don't own an account yet, and would like to register,
            <a href="register.jsp">please click here</a></p>
    </body>
</html>

Here is the registration form, register.jsp:

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
   "http://www.w3.org/TR/html4/loose.dtd"&gt;

<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>Registration</title>
    </head>
    <body>
        <h1>Registration</h1>
        <p>Please fill in the form below, then click on the 'Register'
            button</p>
        <form action="register" method="post">
            <dl>
                <dt><label for="username">Username: </label></dt>
                <dd><input type="text" id="username" name="username"></dd>
                <dt><label for="password">Password: </label></dt>
                <dd><input type="password" id="password" name="password"></dd>
                <dt><label for="password">Verification: </label></dt>
                <dd><input type="password" id="verification" name="verification"></dd>
                <dt><label for="firstname">First name: </label></dt>
                <dd><input type="text" id="firstname" name="firstname"></dd>
                <dt><label for="lastname">Last name: </label></dt>
                <dd><input type="text" id="lastname" name="lastname"></dd>
                <dt><label for="email">E-mail address: </label></dt>
                <dd><input type="text" id="email" name="email"></dd>
                <dd><input type="submit" name="register" value="Register"></dd>
            </dl>
        </form>
    </body>
</html>

Upon submission, the registration fields are posted to a servlet that create a new user in the database, and then redirect to /j_security_check:

String username = request.getParameter("username");
String password = request.getParameter("password");
User user = new User();
user.setUsername(username);
user.setPassword(password);
user.setFirstName(request.getParameter("firstname"));
user.setLastName(request.getParameter("lastname"));
user.setEmail(request.getParameter("email"));

// ... register the user, then if everything is OK, do:

String url = request.getContextPath() + "/j_security_check";
response.sendRedirect(url + "?j_username="
        + URLEncoder.encode(username, "UTF-8")
        + "&j_password="
        + URLEncoder.encode(password, "UTF-8"));
