   Hello Fabio,

   I’ve learned a lot with this video tutorial. The login works perfect and I’ve been able to deploy the project with Netbeans and Payara.
   Just a question. The code
   public boolean isAllowedToSeeUsers(){
   return securityContext.isCallerInRole(“admin”);
   }
   Always returns false. Do you know how to fix it?

   Thanks by this super tutorial

   Ivan

      Add the declaration of the roles in web.xml and it should work then.
      For example

      Administrator
      admin

   Ivan, if the call to securityContext.isCallerInRole(“admin”) always returns false, you must review the configuration of the security constraints in the web.xml to make sure that the JSF pages are properly protected. Make sure that the URL patterns match the corresponding ‘app’ prefix

   Hi Fabio,

   Thank you very much for your help in this tutorial.

   I just have one problem currently when I try login with incorrect details I get the following error. My code is the same of your.

   javax.el.ELException: Expression cannot be null
   …
   JSF1073: javax.faces.FacesException caught during processing of INVOKE_APPLICATION 5 : UIComponent-ClientId=, Message=Expression cannot be null|#]

   I can’t seem to fix this issue, I would be very greatful if you could point out where I might have gone wrong.

   Kind regards,
   T
