Menu
I want to get the Windows username of the user browsing my web page (this is for an intranet). This must be working on IE8, Chrome, and Firefox (Safari would be a plus).
I came across this solution for Java:
http://www.ioplex.com/ : Jespa - Java Active Directory Integration
But this is a proprietary software library and even the example they provide does not work on my web application because we are not using an Apache web server.
A solution in Java would be ideal if anyone got something?
There seems to be some kind of solution in javascript: How to get the windows user name using javascript in google chrome browser for google chrome extension
But nothing is said about IE8 and the Chrome solution seems quite a bit of work.
Thanks in advance

you can use below three files to get the windows user name into JSP session.
1.user1.html
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<body>
<script>
var myWindow;
function openWin() {
myWindow =window.open("http://cmtech9:8080/WinUser/GetUser.jsp","Login","height=50,width=150");
setTimeout(function(){ myWindow.close() }, 3000);
}
</script>
<body onload="openWin();">
</body>
</html>
2.user.js this openes the tab and auto closes the tab
function testing() {
window.setTimeOut("window.close();",1000)
}
3.GetUser.jsp
<%@ page import="sun.misc.BASE64Encoder" %>
<%@ page import="java.util.regex.Matcher"%>
<%@ page import="java.util.regex.Pattern"%>
<head>
<script type="text/javascript" src="user.js"></script>
<script type="text/javascript">
testing()

</head>

return;
}
else if (msg[8] == 3) {

//out.println(s + " ");
length = msg[off+9]*256 + msg[off+8];

s = new String(msg, offset, length);
sess.setAttribute("username", s);
out.println("Hello <span style='position:relative; width:190;"

out.println(s + "</SPAN>");
String result=s.replaceAll("\\W", "");
System.out.println(result);//+""+result.length());
/* System.out.print(n.length()); */
}

nono... That's Firefox. Firefox gives you a ridiculous amount of control over the browser and even outside the browser. You will not be able to do that in chrome because it is sandboxed. Google chrome does not provide API for accessing anything outside the browser.
you CAN make an NPAPI plugin, but that's about it. When the NPAPI plugin runs it asks the user for unrestricted access from the plugin which is kind of suspicious for most.
