Send a document to Java Servlet using JavaScript - Security Issue

Hello,

I need create new option in Adobe Menu to "export/send" current/opened document to Java Servlet.
I using free Adobe Reader DC.

First my idea was to use http method in adobe java script api, but I still fighting with security permission.

My java script code is in User folder: 
C:\Users\insys\AppData\Roaming\Adobe\Acrobat\Privileged\DC\Javascripts\

Below there is a code for http method:

var runExtract = app.trustedFunction(function(doc) {

    app.beginPriv();

        try {

            var params =

             {

                cVerb: "POST",

                cURL: "http://10.179.13.16:8088/ppap/uploadFile",

                aHeaders: [{ name: "fileName", value: doc.documentFileName }],

                oRequest: Collab.documentToStream(doc)

            };

            var responseStream = Net.HTTP.request(params);

        }

        catch (e) {

           app.alert({ cMsg: e.message, cTitle: "Exception" });

        }

    app.endPriv();

});

Code for menu item:

app.addMenuItem({

    cName: "ExportPPAP",

    cUser: "Export to PPAP",

    cParent: "File",

    nPos: 7,

    cEnable: "event.rc = (event.target != null);",

    cExec: "runExtract(event.target)"  

});

But when I want to export this file I receiving:

NotAllowedError: Security settings prevent access to this property or method

Even when I created simply function just to save file (again as separate javascript file in User folder):
Script below:

var myTrustedSaveAs = app.trustedFunction( function ()

{

   app.beginPriv();

        var myTrustedRetn = this.saveAs("/c/MyDocs/" + this.documentFileName);

   app.endPriv();

   return myTrustedRetn;

});

I still receiving:

NotAllowedError: Security settings prevent access to this property or method

Can someone help me how to achive my goa using free version? Maybe someone has other idea, using different function?
