Hello everyone,
I'm currently working on an App that uploads large PDFs to a server. The app
works fine, but everytime, since the PDFs are so large (25MB), the upload takes
a while, and usually after let's say 30 or 40 minutes, I get a "socketException
: broken pipe". I believe that this is due to a timeout or disconnect from the
server (the server cuts the connection I guess), so I moved the upload routine
in a loop that has a try / catch. When an exception is thrown, I try to
reconnect. It works fine. The upload starts where it stopped and completes.
Problem? Well, since the upload is "broken" in two parts (or more if any other
connection loss occurs), the file uploaded is broken too! I mean that's
definatley normal and I unerstand why that happens, but what I'd like to know
is how you can keep the upload on "hold" while trying to reconnect. I just want
to be able to do a complete upload even if there are reconnections. I want my
PDF to uploaded completely. Here is the code I have :
// In
inputStream = new FileInputStream(localFile);
// For upload loop
byte[] bytesIn = new byte[4096];
int read = 0;
// Loop until job is not completed (will try to reconnect if any exception is
thrown)
boolean completed = false;
while (!completed){
try{
// Out
OutputStream outputStream = ftpClient.storeFileStream(remoteFile);
// Transfer
while ((read = inputStream.read(bytesIn)) != -1) {
outputStream.write(bytesIn, 0, read);
transfered += read;
}
// Closing streams
inputStream.close();
outputStream.close();
// Final information
completed = ftpClient.completePendingCommand();
if (completed) System.out.println("Done");
else System.out.println("Failure.");
completed = true;
} // end try
catch (Exception e) {
// Telling the user
System.out.println("Trying to reconnect...");
Thread.sleep(1000);
// Try to reconnect
ftpClient.connect(server, port);
success = ftpClient.login(user, pass);
if (success) {
System.out.println("Connection : OK");
Thread.sleep(1000);
} else {
System.out.println("Failed to connect");
}
// Set passive mode and file type to binary
ftpClient.enterLocalPassiveMode();
ftpClient.setFileType(FTPClient.BINARY_FILE_TYPE);
} // end catch
} // end loop
Any help will be greatly apreciated! Thanks to the community!
Best regards;
Geoffrey
