POSocket: premature end of JPEG file
text
Body
copied!<p>I'm trying to send an image file from a server to a client via a socket. <strong>The socket was previously used to send some strings from the server to the client</strong> (with buffered input/output streams). </p> <p>The trouble is the image file can't be received properly, with "Premature end of JPEG file" error.</p> <p>The server first sends the file size to the client, the client then creates a byte[] of that size, and starts to receive the file.</p> <p>Here are the codes:</p> <p>Server:</p> <pre><code> DataOutputStream dos = new DataOutputStream(socket.getOutputStream()); //Send file size dos.writeInt((int) file.length()); BufferedInputStream bis = new BufferedInputStream(new FileInputStream(file)); byte[] fileBytes = new byte[bis.available()]; bis.read(fileBytes); bis.close(); BufferedOutputStream bos = new BufferedOutputStream(socket.getOutputStream()); bos.write(fileBytes); bos.flush(); </code></pre> <p>Client:</p> <pre><code> DataInputStream dis = new DataInputStream(socket.getInputStream()); //Receive file size int size = dis.readInt(); BufferedInputStream bis = new BufferedInputStream(socket.getInputStream()); byte[] fileBytes = new byte[size]; bis.read(fileBytes, 0, fileBytes.length); </code></pre> <p>More interestingly, <strong>if I let server sleep for about 2 seconds between sending the file size and writing the byte[], then the image is received properly</strong>. I wonder if there's some kind of race condition between the server and the client</p>
