Open a directory of images into separate layers using Adobe extension

I am developing an Adobe extension, from within the extension I want to load a directory of images into separate layers within a document. I am completely impartial to how this is done - so if there is a better approach, please share it with me. My current working method involves using the open() method which opens a file in a new document, then duplicate the layer of the new document into the original document. An example of this can be seen below.
// open new document
var originalDoc = app.activeDocument;
var doc = open( new File( filePath ) );
// duplicate to original document
var layer = doc.activeLayer;
var newLayer = layer.duplicate(originalDoc, ElementPlacement.PLACEATBEGINNING);
// close new document
doc.close(SaveOptions.DONOTSAVECHANGES);
This method is extraordinarily slow, especially for large images. After doing some Googling I discovered that Photoshop has a built-in method for creating an image stack. This feature uses a .jsx script itself and it can be found on GitHub. Looking around online I found a few people trying to load a folders contents as layers, perfect. The main code I was interested in is below.
var folder = new Folder('~/Desktop/MyFolder');
function runLoadStack(folderPath) {
var loadLayersFromScript = true;
// #include 'Load Files into Stack.jsx'
var fList = folder.getFiles('*.png')
var aFlag = true;
loadLayers.intoStack(fList, aFlag);
}
runLoadStack(folder)
I immediately noticed the #include method of importing the stack methods, I can not find any official documentation for this (also not friendly with minification). Also, if the script is not placed with the same directory as Load Files into Stack.jsx it will throw the error Unable to open file: anonymous. And even after solving all of these issues when I run the .jsx script from within my extension using $.evalFile() I am having the same error as if the script is not in the correct directory: Unable to open file: anonymous. Error is being thrown on line 762 of an imported jsx.
Any help resolving the error I am experiencing or simply on how to load an array of image paths into layers (faster method) will be greatly appreciated!
Here is the code I am using within my extension:
var loadLayersFromScript = true;
var strPresets = localize("$$$/ApplicationPresetsFolder/Presets=Presets");
var strScripts = localize("$$$/PSBI/Automate/ImageProcessor/Photoshop/Scripts=Scripts");
var jsxFilePath = app.path + "/" + strPresets + "/" + strScripts + "/Load Files into Stack.jsx";
$.evalFile( new File( jsxFilePath ) );
loadLayers.intoStack( new Folder("/c/Users/Me/teststack").getFiles(), true );

Photoshop's inbuilt scripts has a script to do this here's the github link
https://github.com/ES-Collection/Photoshop-Scripts/blob/master/Import%20Folder%20As%20Layers.jsx
use this script inside your CEP extension

set file attribute filesystemobject javascript

I have created a file as part of a script on a network drive and i am trying to make it hidden so that if the script is run again it should be able to see the file and act on the information contained within it but i am having trouble doing this. what i have so far is:
function doesRegisterExist(oFs, Date, newFolder) {
dbEcho("doesRegisterExist() triggered");
sExpectedRegisterFile = newFolder+"\\Register.txt"
if(oFs.FileExists(sExpectedRegisterFile)==false){
newFile = oFs.OpenTextFile(sExpectedRegisterFile,8,true)
newFile.close()
newReg = oFs.GetFile(sExpectedRegisterFile)
dbEcho(newReg.Attributes)
newReg.Attributes = newReg.Attributes+2
}
}
Windows Script Host does not actually produce an error here and the script runs throgh to competion. the only guides i have found online i have been attempting to translate from VBscript with limited success.
variables passed to this function are roughly declared as such
var oFs = new ActiveXObject("Scripting.FileSystemObject")
var Date = "29-12-2017"
var newFolder = "\\\\File-Server\\path\\to\\folder"
I know ActiveX is a dirty word to a lot of people and i should be shot for even thinking about using it but it really is a perfect fit for what i am trying to do.
Please help.

sExpectedRegisterFolder resolves to \\\\File-Server\\path\\to\\folder\\Register which is a folder and not a file.
I get an Error: file not found when I wrap the code into a try/catch block.
I tested the code on a text file as well, and there it works.
So you're either using the wrong method if you want to set the folder to hidden.
Or you forgot to include the path to the text if you want to change a file to hidden.
( Edit: Or if Register is the name of the file, add the filetype .txt ? )
If you change GetFile to GetFolder as described in https://msdn.microsoft.com/en-us/library/6tkce7xa(v=vs.84).aspx
the folder will get hidden correctly.

How to print a pdf on client side from a groovy webApp?

I am know developping a webapp that as to create a pdf document and print it on client side.
Here is my problem:
i created the pdf using itext and stored it in a shared folder. i did it on a server side.
Now i need to print the created pdf on the client side, the client knows the path of the pdf and can access it.
To be on client side, i am trying to print that document using javascript or jquery.
I tried using embed in my html but it didn't work.
Thx for helping,
here is a working code on server side :
FileInputStream fis = new FileInputStream("test.pdf");
DocFlavor psInFormat = DocFlavor.INPUT_STREAM.AUTOSENSE;
Doc pdfDoc = new SimpleDoc(fis, psInFormat, null);
PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();
PrintService services = PrintServiceLookup.lookupDefaultPrintService();
DocPrintJob job = services.createPrintJob();
job.print(pdfDoc, aset);
and here is what i tried on client side :
// Grabs the Iframe
document.write('<embed type="application/pdf" src="\\SN782629\TempPartage\test.pdf" id="PDF" name="PDF" width="100%" height="100%" />');
var ifr = document.getElementById("PDF");
//PDF is completely loaded. (.load() wasn't working properly with PDFs)
ifr.onreadystatechange = function() {
if (ifr.readyState == 'complete') {
ifr.contentWindow.focus();
if ($.browser.msie) {
document.execCommand('print', false, null);
} else {
window.print();
}
}
ifr.parentNode.removeChild(ifr);
this second code is on the success section of ajax request, i can put the entire function if needed.

fyi: Recommended way to embed PDF in HTML?
and another point: you'll meet a lot of restrictions in different browsers when including pdf from local file system into a page loaded through HTTP.
i'll advice to expose your pdf through url on your server. for example http://myhost/getPdf/SN782629/TempPartage/test.pdf instead of ""\SN782629\TempPartage\test.pdf" and use this link in rendered page.

How to create file(.apk) from URL in Jaggery?

I have application store and applications have their url. I want to download apks from those urls to my jaggery server. Although below code(my first solution) create myApp.apk successfully, its not work properly.
First i tried to below code,
var url = "http://img.xxx.com/006/someApp.apk";
var data = get(url, {});
var file = new File("myApp.apk");
file.open("w");
file.write(data.data);
file.close();
when i print data.data value, its look like
i also tried,
var file = new File("http://img.xxx.com/006/someApp.apk");
file.saveAs("myApp.txt");
Can anyone help me?

.apk files are Android application files, and they are expected to start with PK, because they are actually zip archives!
They're not meant to be unzipped, although you can do it to see some of the application resources (but there are better ways for reverse engineering .apk files such as Apktool, if that's what you're looking for).

According to jaggery documentations, file.write is writing the String representation of the object to the file. So that's why you are getting an apk file which cannot be installed.
However you can make it work using copyURLToFile in apache commons-io java library as follows since jaggery supports java itself and all of WSO2 products have apache commons-io library in their class path.
<%
var JFileUtils = Packages.org.apache.commons.io.FileUtils;
var JUrl = Packages.java.net.URL;
var JFile = Packages.java.io.File;
var url = new JUrl("http://img.xxx.com/006/someApp.apk");
JFileUtils.copyURLToFile(url, new JFile("myApp.apk"));
print("done");
%>
Your file will be stored on $CARBON_HOME directory by default, unless you specified relative or absolute path to the file.

Issues in developing web scraper

I want to develop a platform where users can enter a URL and then my website will open the webpage in an iframe. Now the user can modify his website by simply right clicking and I will provide him options like "remove this element", "copy this element". I am almost through. Many of the websites are opening perfectly in iframe but for a few websites some errors have shown up. I could not identify the reason so asking for your help.
I have solved other issues like XSS problem.
Here is the procedure I have followed :-
Used JavaScript and sent the request to my Java server which makes connection to the URL specified by the user and fetches the HTML and then use Jsoup HTML parser to convert relative URLs into absolute URLs and then save the HTML to my disk in Java. And then I render the saved HTML into my iframe.
Is somewhere wrong ?
A few websites are working perfectly but a few are not.
For example:-
When I tried to open http://www.snapdeal.com it gave me the
Uncaught TypeError: Cannot read property 'paddingTop' of undefined
error. I don't understand why this is happening..
Update
I really wonder how this is implemented? # http://www.proxywebsites.in/browse.php?u=Oi8vd3d3LnNuYXBkZWFsLmNvbQ%3D%3D&b=13&f=norefer

2 issues, pick any you like:
your server side proxy code contains bugs
plenty of sites have either explicit frame-break code or at least expect to be top level frame.

You can try one more thing. In your proxy script you are saving your webpage on your disk and then loading into iframe. I think instead of loading the page you saved on disk in iframe try to open that page in browser. All those sites that restirct their page to be loaded into iframe will now get opened without any error.
Try this I think it an work

My Proxy Server side code :-
DateFormat df = new SimpleDateFormat("ddMMyyyyHHmmss");
String dirName = df.format(new Date());
String dirPath = "C:/apache-tomcat-7.0.23/webapps/offlineWeb/" + dirName;
String serverName = "http://localhost:8080/offlineWeb/" + dirName;
boolean directoryCreated = new File(dirPath).mkdir();
if (!directoryCreated)
log.error("Error in creating directory");
String html = Jsoup.connect(url.toString()).get().html();
doc = Jsoup.parse(html, url);
links = doc.select("link");
scripts = doc.select("script");
images = doc.select("img");
for (Element element : links) {
String linkHref = element.attr("abs:href");
if (linkHref != "") {
element.attr("href", linkHref);
}
}
for (Element element : scripts) {
String scriptSrc = element.attr("abs:src");
if (scriptSrc != "") {
element.attr("src", scriptSrc);
}
}
for (Element element : images) {
String imgSrc = element.attr("abs:src");
if (imgSrc != "") {
element.attr("src", imgSrc);
log.info(imgSrc);
}
}
And Now i am just returning the path where i saved my html file
That's it about my server code
