Yes. I was trying to avoid having to pass the username to the
server when it should already know it.
And actually I guess @RequiredAuthentication might be working,
just on a regular @Service implementing MessageCallback, but not for RPC.

You've implemented an AuthenticationAdapter for
SpringSecurity?
There's really no way of doing it unless you were to
implement your own SessionProvider... even then you could only copy in
information from the HTTPSession.
Party of the reason we separated these concerns so
aggressively was so we could run ErraiBus in something like Netty... without a
Servlet container. I'm certainly open to ideas as to how we can improve
this situation to satisfy a case like yours.

Any ideas why I wouldn’t be able to access Spring Security
information from inside it? It uses ThreadLocal (http://java.sun.com/j2se/1.5.0/docs/api/java/lang/ThreadLocal.html?is-external=true)
for access to the session/login information. I also tried making it use
an InheritableThreadLocal (http://java.sun.com/j2se/1.5.0/docs/api/java/lang/InheritableThreadLocal.html)
holder strategy for the SecurityContext seen below, but it doesn’t seem to be
able to get it through that either.

Errai Authentication
It *should* be enforcing @RequireAuthentication and
@RequireRoles ... let me look into it on my side.

I’m
wondering how authentication works (or is supposed to work) in Errai. It
seems from what I can gather, you’re supposed to use doAuthentication in the
SecurityService, however, even if my custom AuthenticationAdapter does nothing
as it currently does (I was curious to see if I could get Spring Security
authentication information using it to pass it on since I can’t seem to in my
services, which I can’t in there either), but nothing calls isAuthenticated or
anything related to it later on even if I have @RequireAuthentication or
@RequireRoles on my services. In fact, it lets me call the services even
though as far as I think Errai knows, it should have no authentication
principals or roles. Is Authentication incomplete at this point in
time? At this time, I’m not requiring/needing the annotations, but I do
want to get my login information from Spring Security. I
would normally do it in the context of a servlet or jsp as:
try {
SecurityContext context = SecurityContextHolder.getContext();
Object principal = null;
User user = null;
if (context != null) {
Authentication auth = context.getAuthentication();
if (auth != null) {
principal = auth.getPrincipal();
if (principal instanceof User) {
user = (User) principal;
logger.info(user.getUsername());
} else {
logger.debug("Principal is null or not a User");
}
} else {
logger.debug("No authentication");
}
} else {
logger.debug("No context");
}
} catch (Exception e) {
logger.error("Error", e);
}
However,
that doesn’t seem to work, probably because it can’t access the ThreadLocal
since I’m assuming most things in Errai, especially services, get a new
Thread? Is there any way for me to access the remote user from the
servlet? I doubt services get a link to the requesting servlet, correct?
