Problem with using Request dispatcher in my login,jspx

Question

Hi
I am using Jdev 11g and new to adf.
I am trying to work with adf security.
I designed a login.jspx page and loginproxy.jspx accoridng to the following link
http://groundside.com/blog/DuncanMills.php?title=j2ee_security_a_jsf_based_login_form&more=1&c=1&tb=1&pb=1
I have added this code in login.java
     ExternalContext ectx =    FacesContext.getCurrentInstance().getExternalContext();
     HttpServletRequest request =    (HttpServletRequest)ectx.getRequest();
     HttpServletResponse response =    (HttpServletResponse)ectx.getResponse();
     RequestDispatcher dispatcher =   request.getRequestDispatcher("loginnew.jspx");
RequestDispatcher dispatcher =   request.getRequestDispatcher("j_security_check");
    request.setAttribute("j_username", username);
    request.setAttribute("j_password", password);
     dispatcher.forward(request,response);
When it tries to execute dispatch statement, it goes in an infinite loop and finally gets me a stack overflow error and also in the cosole it prints series of exceptions like
ActionListenerImpl><processAction> javax.servlet.ServletException: javax.servlet.ServletException: java.lang.NoClassDefFoundError: Could not initialize class oracle.adf.controller.ControllerException
javax.faces.el.EvaluationException: javax.servlet.ServletException: javax.servlet.ServletException: java.lang.NoClassDefFoundError: Could not initialize class oracle.adf.controller.ControllerExceptionI have to validate the user against database hence i created a login.jspx with a backing bean so that i can access the username and password and validate the credentials against db and redirect user to the appropriate page.
The functionality i want to implement is very simple but i just cant get it to work using adf security.
any help is highly appreciated.
thanks

Hi Pedja,
Thanks for the prompt reply.
I have been following the link you mentioned to create ADF security and successfully implementedthe first part where if i directly give any internal page url it redirects me back to login page.
Instead of using weblogic-sql authenticator, i wanted to manually authenticate the user in loginbean.java where i check the username passowrd against the db.
I had also implemented the method to access username,password mentioned in the following thread
Re: ADF security on my jspx  page as login page
Insted of using authentication.login, i am calling the db method to do the validation.
The thing is after my db validation it does redirect me to the success page(menu.jspx). but when i click links on menu.jspx it redirects me back to login page.
so i understand that user is not yet set in the session.
I am stuck at the point how do i code the login.jspx, currently my login.jspx does not have any j_security_check and i think this is what is creating the problem.
while searching for adding jsecurity in jspx i landed on the blog of 2006 and started using that.
Can you please point me to some link which explains how to code login.jspx , i have been trying hard for couple of days.
Thanks again
