Subject struts 1.2 - HttpServletRequest.getRemoteUser() returns NULL
Date Thu, 15 Oct 2009 04:05:52 GMT


We are developing a web application with Single Sign On (SSO) feature using
struts 1.2 and are using tomcat 6.0 container for deployment. We want to
achieve a scenario similar to Windows Authentication.
For this we want to know the user (user name who has logged in to the
Windows OS)  who has hit the website URL.

I tried to use APIs of HttpServletRequest class.  It gives me client IP
address, but when I try something like httpServletRequest.getRemoteUser()
it returns null (Struts documentation says that getRemoteUser() will return
username only if the user is already authenticated).

Does the HttpServletRequest object contain this information? Is there any
other way to get the user name?

Thanks in advance...
