jsp include does not work

login.html
this file contains code for 2 buttons.The sign in and sign up button which are 2 forms..
connected.jsp
this file contains code for 1 button the one which the user can click and log out.
Controller.jsp 

<%@ page contentType="text/html; charset=UTF-8" %>
<%@ page import="something.*" %>
<%@ page errorPage="Error.jsp" %>

<% 

request.setCharacterEncoding("ISO-8859-7");
String errorMessages = "";
String username = request.getParameter("username");
String password = request.getParameter("password");
if ((password.length() > 0) && !(username.length() > 0)) {
    errorMessages = ("message1");
    throw new Exception(errorMessages);
}
if ((username.length() > 0) && !(password.length() > 0)) {
    errorMessages = ("message2"); 
    throw new Exception(errorMessages);
}
if (!(password.length() > 0) && !(username.length() > 0)) {
    errorMessages = ("message3");
    throw new Exception(errorMessages);
}
DB_something db = new DB_something ();
db.open();
if (request.getParameter("FistName") == null) {
    db.authenticateUser(username, password);
    session.setAttribute("login_status", "connected");

} else {
    String fName = request.getParameter("FistName");
    String lName = request.getParameter("LastName");
    String email = request.getParameter("email");
    String gender = request.getParameter("sex");
    String month = request.getParameter("month");
    String day = request.getParameter("day");
    String year = request.getParameter("year");
    String address = request.getParameter("Adress");
    db.registerUser(fName, lName, email, username, password, gender, month, day, year, address);
    session.setAttribute("login_status", "connected");
}
db.close();
%>
<jsp:forward page="index.jsp" />

DB_something is a class which open and close the connection with database and check if the sign in was ok and also register the user in case of sign up

index.jsp 

    <%
    if (request.getParameter("login_status") == null) {
    %>
    <jsp:include page="login.html" />
    <%
    } else {
        if(1==1)
            throw new Exception("error...");
    %>
    <jsp:include page="connected.jsp" />
    <%
    } 
    %> .  .  .  .

in my index.jsp i tried to include the login.html if the user is not connected(login_status = null) and include the connected.jsp if the user is connected(login_status = "connected") the problem is that it is not working.it is always adding the login.html..I even try add throw exception(the if 1==1 is because otherwise exception was thrown..) but the output is always the same(the exception is never working) Any ideas?

You save the attribute in the session, but trying to extract it from the request.

Instead of the directive -

<jsp:forward page="index.jsp" />

use this:

<jsp:forward page="index.jsp">
    <jsp:param name="login_status" value="connected" />
</jsp:forward>

Or extract the attribute from the session:

if(request.getSession().getAttribute("login_status") == null) {
   ...
}
