Thanks, I guess I''ll hard code for the demo. This will take up to much time with the layout I currently have with menu's changing after a login. The one page logon was simple enough.

Jim,
I believe getRemoteUser is a HttpServletRequest method that only returns an object if the user is logged in. How would they log in? Using container based security. Basic info is on the Strut site:
http://struts.apache.org/userGuide/preface.html#jaas
For more details on this path, try googling. One particular (of many) brief
overview is at:
http://www.cafesoft.com/products/cams/tomcat-security.html
Also, using the role attributes won't work unless you are logged in that way
(the container way). This affects isUserInRole(), getPrincipal,
getRemoteUser(), etc.
Regards, David

David ,
Echo is good...as it turned out this line was returning null,
String userName = ((LogonForm) form).getUsername();
I'm new to java and Tomcat/Struts so I'm strugglig with where to put the
users info once they have successfully logged on.(Logon is just a query to a
database to find unername and password) I guess the LogonForm object is
inaccessable once the LogonAction finishes up.
I thought setting attributes was best, is that the case? Jim barrows on this list suggested I do this,
String x = request.getRemoteUser();
...but it also returns null from an ActionForward
