Re: [ajug-members]: Tomcat: how to get username

[Rob Kischuk <rkischuk@gttx.org>]

Use request.getUserPrincipal().getName() - note that this is a part of 
the HttpServletRequest API, and can be used in any servlet container 
(Tomcat, Weblogic, Websphere, etc).

How do I get at the username?  session.getAttribute() and servletContext.getAttribute() do not appear to have such attributes as "username" set by Tomcat when the username is entered.
