That can have many causes which are not controllable from the server side on. E.g. the enduser decided to shutdown the client or change the server abruptly while still interacting with your server, or the client program … Read more

Is it possible? In which scenario such unitialized exceptions can be thrown?? This is not possible using a conformant Java compiler and conformant Java virtual machine, and by extension a conformant Dalvik virtual machine. The JLS doesn’t allow the e variable to be null at that location Either you’ve got a buggy virtual machine, a … Read more
JavaMail depends on some configuration files to map MIME types to Java classes (e.g., multipart/mixed to javax.mail.internet.MimeMultipart). These configuration files are loaded using the ClassLoader for the application. If the ClassLoader doesn’t function properly, these configuration files won’t be found. You can simply add below lines .. that solves the issue . MailcapCommandMap mc = … Read more
This comes from the serial port driver; it is unhappy about one of the settings. With baudrate being a good candidate, drivers tend to allow only up to 115200. Albeit that this should not be a restriction when this is a dedicated CAN bus product. The best way to tackle this is by using Sysinternals’ … Read more
You’re calling writer.close(); after you’ve done writing to it. Once a stream is closed, it can not be written to again. Usually, the way I go about implementing this is by moving the close out of the write to method. public void writeToFile(){ String file_text= pedStatusText + ” ” + gatesStatus + ” ” + … Read more
Looks like another process had the file open using the file mapping (shared memory) APIs. The find function in Process Explorer should be able to tell you.
A function like this will do it: public static bool IsFileReady(string filename) { // If the file can be opened for exclusive access it means that the file // is no longer locked by another process. try { using (FileStream inputStream = File.Open(filename, FileMode.Open, FileAccess.Read, FileShare.None)) return inputStream.Length > 0; } catch (Exception) { return … Read more
In order to be able to delete the image while it is displayed in an ImageControl, you have to create a new BitmapImage or BitmapFrame object that has BitmapCacheOption.OnLoad set. The bitmap will then be loaded from file immediately and the file is not locked afterwards. Change your property from string TemplateImagePath to ImageSource TemplateImage … Read more
I have found two cases: Losing the network connection when there is still data in the buffer to be flushed. Having the file system fill up (or reaching your user limit for file size) when there is still data in the buffer to be flushed. Both of those examples depend on something happening while there … Read more
