Jaas custom Realm and Login Module

[malik ge]

Hi,
I am new to JAAS and using this link to create custom Realm and Login module.
I have followed all the steps given in that tutorial.

I have created a web application with only one JSP page (index.jsp) as mentioned there and paste the following code in it:

Welcome ${pageContext.request.userPrincipal.name}

I have also add information to web.xml.
When I run the application it only displays the page with Welcome in it.

I would very much appreciate, if some one could guide me with this.
Should I have to create a LogIn page and then go to index.jsp page or some other steps are required to run the application.

Thanks

Finally found a solution.
In web.xml of the web application I placed the code:
<login-config> <auth-method>FORM</auth-method> <realm-name>MyRealm</realm-name> <form-login-config> <form-login-page>/login.jsp</form-login-page> <form-error-page>/loginError.jsp</form-error-page> </form-login-config> </login-config>
