Login module for the J2EE application

Question

Hi ,
I am trying to use the BasicPasswordLoginModule for my J2EE application which will be deployed in the SAP J2EE engine.My application will not be accessed through the portal.
I am having a login screen in my application for which i want to use the already avaliable login module. ie.. BasicPasswordLoginModule.
When i am trying to get the login(). i am getting the following the error.
"javax.security.auth.login.LoginException: No LoginModules configured for BasicPasswordLoginModule".
Please let me know what needs to be done.
PS: The version environment is CE 7.1

Hi Julius
I am totally confused, my application is a pure J2EE application which has only one screen which just displays the details. And i want only the login screen to be implemented. I have gone through a couple of dec from sap which tells to created a custom login module if requiredl but i want to user the FORM based authentication and use the BasicPasswordLoginModule(in-built in WAS)
All that i am doing is written a web.xml with the following information:
<login-config>
   <auth-method>FORM</auth-method>
   <form-login-config>
   <form-login-page>/home.jsp</form-login-page>
   <form-error-page>/relogin.jsp</form-error-page>
   </form-login-config>
  </login-config>
  <security-role>
    <role-name>App_Viewer</role-name>
  </security-role>
web-j2ee-engine with following information:
<security-role-map>
          <role-name>App_Viewer</role-name>
           <server-role-name>Administrator</server-role-name>
     </security-role-map>
     <login-module-configuration>
     <login-module-stack>
     <!-- Contains all login modules used for authentication -->
          <login-module>
          <!-- Contains information about one login module -->
               <login-module-name>BasicPasswordLoginModule</login-module-name>
               <flag>SUFFICIENT</flag>
               <options>
                    <option>
                    <!-- The option UserNamePrefix determines that the user name must start with "Admin" -->
                    <name>UserNamePrefix</name>
                    <value>Admin</value>
                    </option>
               </options>
          </login-module>
     </login-module-stack>
     <security-policy-domain></security-policy-domain>
</login-module-configuration>
And I am not sure, if the above mentioned details are enough. My implementation code is as follows:
try {
          HttpServletRequest request = (HttpServletRequest) FacesContext.getCurrentInstance().getExternalContext().getRequest();
          HttpServletResponse response = (HttpServletResponse) FacesContext.getCurrentInstance().getExternalContext().getResponse();
          request.setAttribute(ILoginConstants.LOGON_UID_ALIAS, this.getUserName());
          request.setAttribute(ILoginConstants.LOGON_PWD_ALIAS, this.getPassword());
          UMFactory.getLogonAuthenticator().logon(request, response, "BasicPasswordLoginModule");
          status = success;
     } catch (Exception e) {
          e.printStackTrace();
          status = e.toString();
In the NWA i have just configured the UserNamePrefix with Admin, thats all . Since the form login authentication method is already configure with the BasicPasswordLoginModule, I left it untouched.
I also implemented a custom login module and deployed it but not sure how to use it in my code.
Please let me know if i am in the rite track. Correct me if i am wrong. At the end of the day i want to use the login screen just to get authenticated. I am also not bothered about the password changing etc.. As the users who are going to use my application are the users in the Identity Management. Few portions of my screen should be allowed to be displayed based on the roles.
PS: My application is not configured in the portal. Its an independent application deployed on the WAS(CE 7.1).
Please advice
