Hey, I'm making a firefox extension and I'm currently trying to get it to send XML data over a local socket to another application that's listening on that socket. Does anyone know what I'm doing wrong in this? Its probably something simple and I'm just having a monday. Thanks.

socketConn: function() {    
var httpLoc = window.top.getBrowser().
             selectedBrowser.contentWindow.location.href;
var outputData = '<?xml version="1.0"?>' +
                 '<site_data>' +
                 '<session_id></session_id>' +
                 'site_url>' + httpLoc + '</site_url>' +
                 '<mime_type></mime_type>' +
                 '<data_file>' + filePath + '</data_file>' +
                 '<capture_mode></capture_mode>' +
                 '</site_data>\n';  
var transportService = Cc["@mozilla.org/network/socket-transport-service;1"]
                      .getService(Ci.nsISocketTransportService);
var transport = transportService.createTransport(["starttls"], 1,"localhost",currentPort, null);
var outstream = transport.openOutputStream(0, 0, 0);
    outstream.write(outputData, outputData.length);
    var stream = transport.openInputStream(0, 0, 0);
var instream = Cc["@mozilla.org/scriptableinputstream;1"]
                    .createInstance(Ci.nsIScriptableInputStream);
    instream.init(stream);    

var dataListener = {
        data : "",
        onStartRequest: function(request, context){},
        onStopRequest: function(request, context, status){
            instream.close();
            outstream.close();
        },
        onDataAvailable: function(request, context, inputStream, offset, count){
            this.data += instream.read(count);
        },
    };//end dataListener
var pump = Cc["@mozilla.org/network/input-stream-pump;1"]
                .createInstance(Ci.nsIInputStreamPump);
    pump.init(stream, -1, -1, 0, 0, false);
    pump.asyncRead(dataListener, null);

}//end socketConn

Please ask questions about this if you don't understand what I'm trying to do with this.
