I am trying to get an InputStream from a URL. The URL can be a opened from Firefox. It returns a json and I have installed an addon for viewing json in Firefox so I can view it there. So I tried to get it from Java by: URL url = new URL(urlString); URLConnection urlConnection = url.openConnection(); BufferedReader reader = new BufferedReader(new InputStreamReader(urlConnection.getInputStream())); But it is throwing an IOException in urlConnection.getInputStream(). I also tried: HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection(); InputStream inputStream = url

I have a WPF application. The page that opens when the app runs in MainWindow.xaml, as set in the StartupUri attribute of the App.xaml file. This page opens fine. However, if I try to open any other windows using the Show or ShowDialog method I get an IOException in the InitializeComponent method saying "Cannot locate resource 'Window1.xaml'" (or whatever the file is called).

FINAL UPDATE It was our firmware the whole time. Embarrassing to a degree, but I'm happy we can move forward and I can put learning Java off for another day. My answer is below. UPDATE So I have more or less given up on this. I think it is a bug that goes down to the API but I have neither the time, resources nor skill-set to get to the bottom of it. I think there exists some hardware to whom Windows just gives the middle finger. I have downloaded Eclipse, switched to Java and will try to see if that works. If not, you'll see me back here. However, I would absolutely love to solve this and so

The following code throws a IOException with the message: "The specified registry key does not exist." HttpClient client = new HttpClient(); Uri uri = new Uri("http://www.google.com"); client.GetAsync(uri); This is just in a console app in Main. It looks like the error is being thrown by mscorlib.dll!Microsoft.Win32.RegistryKey.Win32Error(int errorCode, string str). I have no idea why this error is being thrown or how to start debugging it. Edit stack trace: at Microsoft.Win32.RegistryKey.Win32Error(Int32 errorCode, String str) It's just 1 line and there is no inner exxception etc.. The call

This is the code I currently have: public class FileStatus extends Status{ FileWriter writer; public FileStatus(){ try { writer = new FileWriter("status.txt",true); } catch (IOException e) { e.printStackTrace(); } } public void writeToFile(){ String file_text= pedStatusText + " " + gatesStatus + " " + DrawBridgeStatusText; try { writer.write(file_text); writer.flush(); writer.close(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } Everything works as expected (The file is written to when the writeToFile method is called). However when the writeToFile
