Embed SWF file in firefox add-on (no SDK)

I have a problem with a firefox extension i'm developing.

I need to add an SWF file in the page. If I load it from a remote server, it works fine:

myObj2.setAttribute("data",'http://www.mySite.com/myFile.swf');
myPar1.setAttribute("value",'http://www.mySite.com/myFile.swf');

It works fine but is not accepted for the review.

so I created a resource dir in the manifest:

resource   ldvswf   swf/

and changed the script into:

myObj2.setAttribute("data",'resource://ldvswf/myFile.swf');
myPar1.setAttribute("value",'resource://ldvswf/myFile.swf');

but it doesn't work. The folder resource://ldvswf is ok as i tested loading an image and I see it.

The reviewer wrote me that for flash file it "requires doing so via a file: URL", but I don't know how to manage, I tested:

'file: resource://ldvswf/myFile.swf'
'file://resource://ldvswf/myFile.swf'
'file://ldvswf/myFile.swf'
'file: ldvswf/myFile.swf'

And nothing works.

Any suggestion for the right path?

Thanks a lot!

Update: the editor wrote me:

You need a file URL that points to an actual file. If your extension is unpacked, something like the following should do:

Services.io.newFileURI(Services.io.newURI("resource://ldvswf/myFile.swf", null, null)
                              .QueryInterface(Ci.nsIFileURL).file)
          .spec

But I don't understand how to plce it to replace:

myObj2.setAttribute("data",'http://www.mySite.com/myFile.swf');
myPar1.setAttribute("value",'http://www.mySite.com/myFile.swf');

I made some test like:

var file = Services.io.newFileURI(Services.io.newURI("resource://ldvswf/myFile.swf", null, null).QueryInterface(Ci.nsIFileURL).file).spec ;

myObj2.setAttribute("data",file);
myPar1.setAttribute("value",file);

But I get this error message:
Error: NS_NOINTERFACE: Component returned failure code: 0x80004002 (NS_NOINTERFACE) [nsIFileURL.file]

make sure you have a line in package.json:

   "unpack": true,

at the same level as name, title, author etc. Note that true does not have the quotes.

try breaking the line like this:

var file = Services.io.newURI("resource://ldvswf/myFile.swf", null, null).QueryInterface(Ci.nsIFileURL).file;
alert(file.path)
var file = Services.io.newFileURI(file).spec ;
alert(file)

the first alert() should give a local system path like 'c:\folder\filename...' the second should give a file:// URI

so what do you get?

Have you tried using contentaccessible=yes in your chrome.manifest, like this:

content  package_name   content/ contentaccessible=yes

I tested it with an image in a local web page and it worked, don't know for SWF:

<img src="chrome://package_name/skin/window.png"/>

Another approach is to get the file URI of the chrome:// (not resource://) file like this:

function chromeToPath (aPath){
    if (!aPath || !(/^chrome:/.test(aPath))){
       return null; //not a chrome url
    }
    var Cc = Components.classes, Ci = Components.interfaces;
    var spec, url, file;
    var ios = Cc['@mozilla.org/network/io-service;1'].getService(Ci["nsIIOService"]);
    var uri = ios.newURI(aPath, "UTF-8", null);
    var crs = Cc['@mozilla.org/chrome/chrome-registry;1'].getService(Ci["nsIChromeRegistry"]);
    var fph = Cc["@mozilla.org/network/protocol;1?name=file"].createInstance(Ci.nsIFileProtocolHandler);
    spec = crs.convertChromeURL(uri).spec;
    return spec;
}

usage:

chromeToPath('chrome://package_name/skin/window.png')

and it will return the file:// URI of the file.

If you test this, better make sure the extension is unpacked (unzipped) on install: in install.rdf: <em:unpack>true</em:unpack>
