Unfortunately, you cannot get the list of roles for the user from that object. The best you can do using the servlet API is to ask the request if the currently-logged-in user is in a specific role (you have to know what role you want to ask for up front). I've always maintained a separate "user" object in the session that contains information like this, so you can consult it to, say, determine the complete list of roles a particular user has without having to check each one individually.

Re: Retrieve User Role
Hi Ben
You can get it from the request. In JSP you can access the request
implict object to get the value of the
HttpServletRequest#getRemoteUser() method ...
"Returns the login of the user making this request, if the user has been
authenticated, or null if the user has not been authenticated."
(quote from j2ee docs for HttpServletRequest)
The exact syntax to use depends upon whether or not you are using EL.
If you are using tags..
<% String username = request.getRemoteUser() %>
and in EL you can use the 'pageContext'. Try:
${pageContext.request.remoteUser} /// I think... you may need to check.
and use as you see fit...

Retrieve User Role
I have set up login security for some of the pages in my website. I have a JDBCRealm setup and working correctly. But now I want to change the layout of my pages (all jsp pages) according to the user that is logged in. How do I retrieve information about the user that is actually logged in? Mainly I want the user role or the user name but I can't seem to get it from the session. Any help would be appreciated.
