Re: ActiveXObject - Automation Server Cannot Create Object

Followup: I came to tentative understanding of the issue.

Though ActiveXObject is called by JavaScript, but it's not JavaScript
native. It's a proprietary Microsoft object, understood by IE.

Workaround Good-Enough Solution:

In JavaScript (which is embedded in HTML):

// 1. Get the value of Windows local environment variable %USERNAME%
function getUserName() {
if (!document.all) {
alert("Available only with Internet Explorer.");
return;
}
var ws = new ActiveXObject("WScript.Shell");
var un = ws.ExpandEnvironmentStrings("%USERNAME%");
return un;
}

// 2. Write the %USERNAME% value to a cookie.
// Cookie lifespan value is set to "0" days, which means for the
current session only.
createCookie("userName",getUserName(),0);
function createCookie(name,value,days) {
if (days) {
var date = new Date();
date.setTime(date.getTime()+(days*24*60*60*1000));
var expires = "; expires="+date.toGMTString();
}
else var expires = "";
document.cookie = name+"="+value+expires+"; path=/";
}

// 3. From GWT side, in Java code, call GWT static method
Cookies.getCookie("userName")

String uName = Cookies.getCookie("userName");
