I need help with redirecting to different page after login.

I manage to do normal login redirect to appDashboard.jsp however, what I'm trying to do is if the user first-time login into the system then they will be redirected to appSetup.jsp and if not they will be redirected to appDashboard.jsp. How can I do this?

The data for FIRST_TIME in database inserted as yes during registration. Below are my codes.

appLogin.jsp

<!-- Form Module-->

<div class="module form-module">

    <div class="toggle"><i class="fa fa-times fa-pencil"></i>

        <div class="tooltip" style=" margin-right: -110px;">Not a member? <a href="appRegister.jsp" style="color: gray">Register Here</a></div>

    </div>

    <!-- LOGIN FORM-->

    <div class="form">

        <h2>Login to your account</h2>

        <form action="AppLogin">

            <input type="text" placeholder="Username" name="appusername"/>

            <input type="password" placeholder="Password" name="apppassword"/>

            <button type="submit" name="login">Login</button>

        </form>

    </div>

    <div class="cta"><a href="forgotPassword.jsp">Forgot your password?</a></div>

</div>

ApplicantLoginServlet.java

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

    try {

        ApplicantBean applicant = new ApplicantBean();

        applicant.setUsername(request.getParameter("appusername"));

        applicant.setPassword(request.getParameter("apppassword"));



        applicant = ApplicantDA.Login(applicant);



        if(applicant.isValid()) {

            HttpSession session = request.getSession(true); //creating session

            session.setAttribute("currentApplicant", applicant);

            PrintWriter out = response.getWriter();



            String firstTime = applicant.getFirstTime();

            if(firstTime == "yes" ) {

                System.out.println("ft " + firstTime);

                response.setContentType("text/html");  

                response.setContentType("text/html");
