Thread: File Not Saving

I'm having a bit of an annoying issue which I cannot figure out.
My goal is that I have an xml file which I am attempting to save. It is doing this saving via FTP, and the file which I am writing to is on a local VM (with Apache and FileZilla enabled on the VM). I can write other files a similar way, but this one file is not working for some reason.

Here is a unit test I have to narrow down the issue:

@Test
	public void testUpdateConfigurations() {
		ConfigurationsQuery.readConfigurationsFile();
		// Increment the simulation date by one month
		ConfigurationProcess.setMonthData();
 
		// Get the weather data for the new month
		Map<WeatherType, WeatherEvent> weatherEvents = WeatherQuery.getWeatherEventsForMonth(Database.getSystemDate().get(Calendar.MONTH));
		// Clear the old weather data and set the new weather data
		Database.getWeather().clear();
		ConfigurationProcess.setWeatherData(weatherEvents);
		logger.info(SimulationDatabase.getWeatherEventsForMonth().toString());
		// Set the new simulation dates
		ConfigurationProcess.setSimDates();
		Assert.assertTrue(UpdateDatabaseQuery.updateConfigurations());
	}

The updateConfigurations() method can be found here:

public static boolean updateConfigurations() {
		int count = 0;
		while(!ConfigurationsQuery.writeConfigurations()) {
			if(count>=5) {
				logger.severe("Configurations Failed To Update after 5 attempts...");
				return false;
			}
			count++;
		}
		return true;
	}

The writeConfigurations() method can be found here:

public static boolean writeConfigurations() {
		DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
		try {
			DocumentBuilder builder = factory.newDocumentBuilder();
			Document document = builder.newDocument();
 
			// Create Root
			Element root = document.createElement("config");
			// I took out all the code which creates the xml file, to keep this short
			// Append the root
			document.appendChild(root);
 
			URL url = new URL(SharedConstants.HOST_URL+FILE_NAME);
			URLConnection curlconn = url.openConnection();
			curlconn.setDoOutput(true);
			logger.info("Do Output True");
 
			java.io.OutputStream out = curlconn.getOutputStream();
			if(XMLUtilities.printDocument(document, out)) {
				out.close();
				return true;
			}
		} catch(Exception ex) {
			ex.printStackTrace();
		}		
		return false;
	}

And, lastly, the printDocument() method can be found here:

public static boolean printDocument(Document doc, OutputStream out) {
	    TransformerFactory tf = TransformerFactory.newInstance();
	    Transformer transformer = null;
		try {
			transformer = tf.newTransformer();
		} catch (TransformerConfigurationException e) {
			e.printStackTrace();
			return false;
		}
	    transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "no");
	    transformer.setOutputProperty(OutputKeys.METHOD, "xml");
	    transformer.setOutputProperty(OutputKeys.INDENT, "yes");
	    transformer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
	    transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "4");
 
	    try {
			transformer.transform(new DOMSource(doc), new StreamResult(new OutputStreamWriter(out, "UTF-8")));
		} catch (UnsupportedEncodingException e) {
			e.printStackTrace();
			return false;
		} catch (TransformerException e) {
			e.printStackTrace();
			return false;
		}
	    return true;
	}

I am not getting any exceptions thrown or error messages in the log, and the test passes successfully. The file is just not being updated. Does anyone have any thoughts? I know there is a lot here, so please ask questions if you need something clarified.

EDIT:
Here is a list of things I've tried so far to debug the issue:
1. Remove the old file and ran again to see if the file would be created: the test still passed, but the file was not created
2. Tested against the real server to see if it was a problem with my VM: the test still passed, but the file on the real server was not changed
3. Added a second transform which prints to the console instead of a file, by changing the tranform's Result parameter to System.out: the xml file is successfully printed to the console correctly, which proves there is no issue with the xml object or the transforming mechanism. Still no change to the file.
4. Attempted to flush the output stream before closing it: the test still passed, but the file was not changed

So after banging my head against the wall for like a week over this, I found out what happened. The url I was using was the http address to the file, not the ftp address which I had forgotten that I needed to use, lol. So...this is now resolved, and I feel like an idiot.
