HTTP Request using Mozilla Rhino

I would like to write a JavaScript code processed with Mozilla Rhino that can do a simple HTTP GET request, which fetches a text string from a URL.
The problem is that, I couldn't find any support in Rhino to do any kind of HTTP requests. Besides, I don't have access to the Rhino instance itself, it's running via TopBraid Composer IDE for ontology modelling. I believe any idea about a simple library that I can import within my JavaScript file maybe a good solution.
Any help?
Thanks.

Okay, so it wasn't that difficult to figure it out. This one works via TopBraid Composer and without importing any JAVA libraries. Here's the answer in case anyone needs it later on.
var resourceURL = new java.net.URL(
'http://someurl');
var urlConnection = resourceURL.openConnection();
var inputStream = new java.io.InputStreamReader(urlConnection
.getInputStream());
var bufferedReader = new java.io.BufferedReader(inputStream);
var inputLine = bufferedReader.readLine();
bufferedReader.close();
var jsString = String(inputLine);
return jsString;

Adobe InDesign CS6 "undefined is not an object"

I am new to InDesign scripting though I do have experience with Javascript.
I created a new menu item as you will see in the script below, which I planned to use it to call another script onclick. However I am facing some issues, so I decided to delete the menu item and start over. But at line 10, I get the message "undefined is not an object", which I can't figure out why it's causing a problem.
Any help will be appreciated.
//#targetengine "ImportFolder"
//var myMainMenu = app.menus.item("Main");
//var myCustomMenu = myMainMenu.submenus.item("Import Folder");
//var myCustomMenu = myMainMenu.submenus.add("Import Folder");
//var mySampleScriptAction = app.scriptMenuActions.add("onInvoke", function() {
//app.doScript(new File ("/C/Program Files (x86)/Adobe/Adobe InDesign CS6/Scripts/Scripts Panel/importFiles.jsx" ));});
//delete the menu
var myMainMenu = app.menus.item("Main");
try{
var myCustomMenu = myMainMenu.submenus.item("Import Folder");
myCustomMenu.remove();
}catch(myError){}

Try re-installing Indesign. If the scripting library dll lost its registration, it could cause all of the scripts to fail.
...wait a minute - are you trying to use this script from the Extendscript Toolkit? If you are, you have to change engines.
Also, if you have more than one version of CS on your system, you need to make sure you use the Extendscript Toolkit that matches the version of your InDesign - in other words, EXTK CS6 for IND CS6.
Another thing to try is to remove the new from your doscript command. I like to wrap mine in a function like this:
//run a script from the CS6 Script Panel Directory (be sure to add the file extension
function RunMyScript(whatscriptname){
app.doScript(File("/C/Program Files (x86)/Adobe/Adobe InDesign CS6/Scripts/Scripts Panel/" + whatscriptname));
}

How do I use jQuery in Windows Script Host?

I'm working on some code that needs to parse numerous files that contain fragments of HTML. It seems that jQuery would be very useful for this, but when I try to load jQuery into something like WScript or CScript, it throws an error because of jQuery's many references to the window object.
What practical way is there to use jQuery in code that runs without a browser?
Update: In response to the comments, I have successfully written JavaScript code to read the contents of files using new ActiveXObject('Scripting.FileSystemObject');. I know that ActiveX is evil, but this is just an internal project to get some data out of some files that contain HTML fragments and into a proper database.
Another Update: My code so far looks about like this:
var fileIo, here;
fileIo = new ActiveXObject('Scripting.FileSystemObject');
here = unescape(fileIo.GetParentFolderName(WScript.ScriptFullName) + "\\");
(function() {
var files, thisFile, thisFileName, thisFileText;
for (files = new Enumerator(fileIo.GetFolder(here).files); !files.atEnd(); files.moveNext()) {
thisFileName = files.item().Name;
thisFile = fileIo.OpenTextFile(here + thisFileName);
thisFileText = thisFile.ReadAll();
// I want to do something like this:
s = $(thisFileText).find('input#txtFoo').val();
}
})();
Update: I posted this question on the jQuery forums as well: http://forum.jquery.com/topic/how-to-use-jquery-without-a-browser#14737000003719577

Following along with your code, you could create an instance of IE using Windows Script Host, load your html file in to the instance, append jQuery dynamically to the loaded page, then script from that.
This works in IE8 with XP, but I'm aware of some security issues in Windows 7/IE9. IF you run into problems you could try lowering your security settings.
var fileIo, here, ie;
fileIo = new ActiveXObject('Scripting.FileSystemObject');
here = unescape(fileIo.GetParentFolderName(WScript.ScriptFullName) + "\\");
ie = new ActiveXObject("InternetExplorer.Application");
ie.visible = true
function loadDoc(src) {
var head, script;
ie.Navigate(src);
while(ie.busy){
WScript.sleep(100);
}
head = ie.document.getElementsByTagName("head")[0];
script = ie.document.createElement('script');
script.src = "http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js";
head.appendChild(script);
return ie.document.parentWindow;
}
(function() {
var files, thisFile, win;
for (files = new Enumerator(fileIo.GetFolder(here).files); !files.atEnd(); files.moveNext()) {
thisFile = files.item();
if(fileIo.GetExtensionName(thisFile)=="htm") {
win = loadDoc(thisFile);
// your jQuery reference = win.$
WScript.echo(thisFile + ": " + win.$('input#txtFoo').val());
}
}
})();

This is pretty easy to do in Node.js with the cheerio package. You can read in arbitrary HTML from whatever source you want, parse it with cheerio and then access the parsed elements using jQuery style selectors.

evaluate system command or python script in firefox browser using javascript

May be duplicate.
I would like to write javascript which can execute linux command in firefox (seems to be impossible but asking with hope)
from googling, found that it is possible for IE through "ActiveXObject".
here is sample code:
<SCRIPT type="text/javascript" LANGUAGE="JavaScript">
function executeCommands(inputparms)
{
// Instantiate the Shell object and invoke
its execute method.
var oShell = new ActiveXObject("Shell.Application");
var commandtoRun = "C:\\Winnt\\Notepad.exe";
if (inputparms != "")
{
var commandParms = document.Form1.filename.value;
}
// Invoke the execute method.
oShell.ShellExecute(commandtoRun, commandParms,
"", "open", "1");
}
</SCRIPT>
So, Is there any equivalent of ActiveXObject in javascript for mozilla apps?
I'm quite new to javascript so please, correct mistakes if any.
Thanks!

In a Firefox add-on you can use nsIProcess. Something along these lines:
var file = Components.classes["#mozilla.org/file/local;1"]
.createInstance(Components.interfaces.nsILocalFile);
file.initWithPath("C:\\Winnt\\Notepad.exe");
var process = Components.classes["#mozilla.org/process/util;1"]
.createInstance(Components.interfaces.nsIProcess);
process.init(file);
process.runAsync(["c:\\file.txt"]);
This API is only accessible to privileged code of course.

No, it's not possible to run arbitrary, native commands on the client's machine.

Launching winword with a file using ActiveX

How can I launch Word with a document path from activeX like for example:
function RunWord(cmdline, args){
var v;
v = new ActiveXObject("Shell.Application");
v.ShellExecute(cmdline+" "+args);
}
where cmdline is 'Word' that is a shortcut link in one of the system folder and args is the path to file like 'C:\Projects\Schedule.doc'
The problem is it combine the string like 'Word C:\Projects\Schedule.doc' and then give an error saying it does not find this application, however when I launch word alone without args it works ok.
Any ideas ?

Do you need to escaped the backslashes in your filename? I.e. use
'C:\\Projects\\Schedule.doc'
instead of
'C:\Projects\Schedule.doc'
