let me give you an idea about how the system works.

I am using JAAS login module for login and role management. I can access specific pages depending on the role i have.

I type my url in the address bar, hit enter.

The login page appears and after correct login, it redirects me to the correct page(for now lets call it page1.jsf).

I want to call a server side method on page load.

Can you help me please?

** EDIT **

Assume i have to access page1.jsf which is accessible to role1 only.

In the address bar, i type http://localhost:8080/myapp/page1.jsf

JAAS shows up the login page and after correctly inputting the credentials, i am redirected to page1.jsf

As soon as page1.jsf is requested or on page load, i want to call a server side method from my class to reload page1.jsf

    If you are using JSF 2, you can use the above page snippet:

    <html xmlns="http://www.w3.org/1999/xhtml"
  ... >
 <f:view contentType="text/html">
    <f:event type="preRenderView" listener="#{permissionManager.checkRoles}" />
    <f:attribute name="roles" value="ROLE" />

  ...
  </f:view>
</html>

    you can add an attribute containing the role and in the PermissionManager.checkRoles() perform redirect to the corret page.

    @Named
@ApplicationScoped
class PermissionManager { 
  ...
  public void checkRoles(ComponentSystemEvent event) {

       String acl = "" + event.getComponent().getAttributes().get("roles");
       //Check user role
       ...
       //Redirect if required
       try {

        ConfigurableNavigationHandler handler = (ConfigurableNavigationHandler) context
                .getApplication().getNavigationHandler();
        handler.performNavigation("access-denied");
    } catch (Exception e) {
        ...
    }

   }

}
