GlasshFish basic authentication default username and password

I'm trying to implement basic authentication in a java ee project but I cant find what the default username and password is (if there is any).

My web.xml looks like this:

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">

    <security-role>
        <description/>
        <role-name>user</role-name>
    </security-role>
</web-app>

My index page is a login form which should start the session upon successful login..this kinda work and it allows me to see the next page..Now if I dont go through the index page and I type in the url of that second page, a login window pops up but no matter what I type in there it doesnt let me see the page...I tried admin-adminadmin, admin-pass, admin-admin and others but nothing works..

Any help would be really appreciated!!! Thanks!!!
