How to retrieve an user Principal?

Hello,
how can i retrieve an user principal?

I don't want to get it from the request, but directly from the
underlying security framework.

My application, when developed in Jboss, uses an instruction like the following:

org.jboss.security.SecurityAssociation.getPrincipal();

Is there something similar in Tomcat? May you please point me to the
correct resource (documentation, web page)?

Thanks

sorry, I thought you where pissing on me. I didn't understand your
real intentions.
I will manage the request to get what I'm looking for.

Thanks,

Go and troll somewhere else.

I told you that JBoss uses thread local storage.
1. Request comes in.
2. According to the Servlet spec the request is
    parsed and user determined.
3. It is added to the thread local.
4. getPrincipal() ... return (Principal) threadPrincipal.get();

So it does all that for you. Without J2EE container,
you'll need to use the the Servlet spec.

Maybe, but it doesn't require I pass the request as an argument, ir
returns the principal from whenever I call it in the code, simply,
even in those classes which doesn't have a request variabile.

It allows me writing security helpers, for instance, which can be used
from within pluggable JAAS Login Modules, where the request is not
available at all.

So my question follows: is there anything similar in Tomcat?

cheers

JBoss getPrincipal() figures that from the request,
so where the problem?
