Calling Active-x object from Javascript inside Java code

Question

I'm trying to get windows username from liferay portlet in java code using javascript and active-x. When I run the code only with javascript and acitive-x on plain HTML it works. But when I put it in java, it doesn't work. Here is my code:

String script = "function getUser() {return ((new ActiveXObject('WScript.NetWork')).UserName); }";  
try {
    engine.eval(script);
} catch (ScriptException e) {
    e.printStackTrace();
}  

Invocable inv = (Invocable) engine;  

try {
    log.info("try invoke script");
    String teste = (String) inv.invokeFunction("getUser");
    log.info("meu teste " +teste);
} catch (ScriptException e) {
    e.printStackTrace();
} catch (NoSuchMethodException e) {
    e.printStackTrace();
}

When I change the content on function for somthing else like returning string it prints the result.

S3iB, does it returns the user who are acessing the page or the user loggen on the server? — user2661250, Jan 23 '14 at 13:01
S3iB, your answer doesn't solve my problem. I want the user who a acessing the page rather than user who a logged in to server wich is always same! — user2661250, Jan 23 '14 at 14:05

Java-s JavaScript doesn't have Active X capabilities, but you don't have to use JavaScript to get the running machines users username. Get login username in java

If you want to know client-s OS-s username then one approach would be to use client side JavaScript to find it out and submit this information to server side via AJAX.
