Form Authenticating the portal or jsp page

Question

Before accessing a jsp page, I want the user to authenticate using login.jsp using the user role I created in console.
But when I hit the page, its not going to login.jsp. Instead its going directly to it. Please find the web.xml and weblogic.xml that I changed below,
--web.xml
<security-constraint>
<web-resource-collection>
<web-resource-name>webtest</web-resource-name>
<url-pattern>/portlets/tools/wnxinterface/wnxInterface.jsp</url-pattern>
</web-resource-collection>
<auth-constraint>
<role-name>wnuser</role-name>
</auth-constraint>
<user-data-constraint>
<transport-guarantee>NONE</transport-guarantee>
</user-data-constraint>
</security-constraint>
<!--turn on identity assertion-->
<login-config>
<auth-method>CLIENT-CERT,FORM</auth-method>
          <realm-name>myrealm</realm-name>
<form-login-config>
<form-login-page>login.jsp</form-login-page>
<form-error-page>error.jsp</form-error-page>
</form-login-config>
</login-config>
<security-role>
          <role-name>AuthenticatedUserRole</role-name>
</security-role>
<security-role>
          <role-name>wnuser</role-name>
</security-role>
--weblogic.xml
<wls:security-role-assignment>
<wls:role-name>AuthenticatedUserRole</wls:role-name>
<wls:principal-name>AuthenticatedUsers</wls:principal-name>
</wls:security-role-assignment>
<wls:security-role-assignment>
     <wls:role-name>wnuser</wls:role-name>
     <wls:principal-name>wngroup</wls:principal-name>
</wls:security-role-assignment>
I created the wnuser in myrealm in my console. So I am trying to password protect the wnxInterface.jsp page.
Actually I have this wnxInterface.jsp as a portlet inside my portal. Is it similarly possible to authenticate the portal itself?
Thanks in advance

1. yes: URL u = new URL(this.getCodeBase(),"../relativeFolder/file.whatever");

2. yes: using JSObject you can call javaScript methods that can do it for you or retreive the
componenet directly.
