This'll do it for you:
String userSystemName = System.getProperty("user.name");

Did you test this?
I wonder to know how a software which executes on a server can get the 
currently logged in user on a remote client machine using this command.

For me, using a jsp or a servlet or a servlet, it is not directly 
possible to get the currently logged in user as the jsp or servlet is 
invoked through HTTP which is anonymous.

Maybe did I missing the real intent of the initial question

   Yes. The OP did not specify whether he wanted the user currently 
logged in on the client or the user currently logged in on the server.

Have a look at http://jcifs.samba.org/src/docs/ntlmhttpauth.html.
Only works with MS Internet Explorer.

A more general solution could consist in implementing a filter in the 
application server which will invoke a SSO.  It is more complicated but 
it works everywhere with a better security.

A good example is documented here

No, that is exactly what I meant. I know that this is possible in
combination with the IIS. That works afaik with the so called NTLM
'protocol'. Where the Browser sends the login information with a request.
I wonder if there is a servlet or anything like that, that emulates the
behavior of the IIS.

Sorry - my mistake: I meant the currently logged in user on the client side.

Ok, i read this. But as I understand this is used to authorize the access to
any file sharing. How is it then possible to get the username of the user?
Can I then use the getRemoteUser() method?
I need the username for a LDAP (ADS) Lookup for the groups the user belongs
to.

Wedgetail claims to do that: http://www.wedgetail.com/jcsi/sso/

You didn't say you want it for free, did you ?

Once the filter has got the authorisation, it can add the user id in the 
  HTTP query before returning to the actual serlet invocation.  Just 
read the use of the servlet filters.  I do not have a good pointer here 
but google should do it for you!
