I am getting the following error frequently while retrieving file object from database column. How can I resolve this problem?

Your HTTP client disconnected.

This could have a couple of reasons:

  • Responding to the request took too long, the client gave up
  • You responded with something the client did not understand
  • The end-user actually cancelled the request
  • A network error occurred
  • ... probably more

You can fairly easily emulate the behavior:

URL url = new URL("http://example.com/path/to/the/file");

int numberOfBytesToRead = 200;

byte[] buffer = new byte[numberOfBytesToRead];
int numberOfBytesRead = url.openStream().read(buffer);

Your log indicates ClientAbortException, which occurs when your HTTP client drops the connection with the server and this happened before server could close the server socket Connection.
