Hi Adam,
If you're using container-managed login, something like this should work:
<c:if test="${pageContext.request.userPrincipal != null}">
...
</c:if>
However, if you've overridden the default login behavior using your own
LoginHandler, there isn't a very discoverable way to do this. I think
what we need are protected getUserPrincipal() and isUserInRole() on
FlowController, which would be aware of the login-override mechanism.
In the meantime, you should be able to get what you need by passing the
following value to your JSP as a page input (or exposing it however you
normally expose data to your pages):
FlowControllerHandlerContext fcContext = new
FlowControllerHandlerContext(getRequest(), getResponse(), this);
boolean loggedIn =
(Handlers.get(getServletContext()).getLoginHandler().getUserPrincipal(fcContext)
!= null);
I'll open a bug on the missing API; meanwhile, if you have any
problems/questions about this, let me know.
