Question

I try to use servlet request to retrieve the user name after basic authentication. But I found no such method to retrieve user name. There is method to get the user role, but not the name?

Anyone know how to get the user name?

Answer 1

In case of HTTP BASIC authentication, the username is available by HttpServletRequest#getRemoteUser().

So, in Servlet:

String username = request.getRemoteUser();
// ...

and in JSP:

<p>Welcome, ${pageContext.request.remoteUser}</p>

Further, the user principal is available by HttpServletRequest#getUserPrincipal().
