copied!<p>Maybe your file is bigger than 1024 bytes? It's bigger than the buffer</p> <p><b>Edit: </b> The error is because of this line:</p> <pre><code>FileOutputStream fout=new FileOutputStream(path); </code></pre> <p>Comment it out because you don't really do anything with it. It's in the serverside code one of the first lines in your first try-catch </p> <p>This line opens an output-Stream to your file. Nothing happens with this stream but it's also not closed.</p> <p>This causes not only the error on the client side (because no data is transfered), but also wipes out all data you store in your file.</p> <p><b>Edit 2:</b></p> <p>I tried a picture with the bytesize of 305564</p> <p>and although the buffer on the client side was big enough i just got 65536 bytes of data transferred at the same time.</p> <p>For big files you have to use loops to get all needed data filled in to your buffer:</p> <p>I tested it out because i wanted to get it work, too.</p> <p><b>Client Side</b></p> <pre><code>try { Socket sock = new Socket("127.0.0.1", 12345); byte[] mybytearray = new byte[65536]; System.out.println("1"); InputStream is = sock.getInputStream(); System.out.println("2"); File recievedFile=new File(fileName+"_res.jpg"); System.out.println("3"); recievedFile.createNewFile(); System.out.println("4"); FileOutputStream fos = new FileOutputStream(recievedFile); System.out.println("5"); BufferedOutputStream bos = new BufferedOutputStream(fos); System.out.println("6"); int loopcount = is.read(); for(int i = 0; i < loopcount; i++) { int bytesRead = is.read(mybytearray, 0, mybytearray.length); System.out.println(bytesRead); System.out.println("7"); bos.write(mybytearray, 0, bytesRead); System.out.println("8"); bos.flush(); } System.out.println("9"); bos.close(); sock.close(); } catch(Exception e) { e.printStackTrace(); } </code></pre> <p><strong>Server Side</strong></p> <pre><code> try { ServerSocket servsock=new ServerSocket(12345); Socket sock = servsock.accept(); int bufferSize = 65536; byte[] mybytearray = new byte[bufferSize]; BufferedInputStream bis = new BufferedInputStream(new FileInputStream(file)); OutputStream os = sock.getOutputStream(); int loopcount = (int) (file.length()/bufferSize)+(file.length()%bufferSize==0?0:1); System.out.println("loopcount: "+loopcount); os.write(loopcount); os.flush(); for(int i = 0; i < loopcount; i ++) { System.out.println(i); bis.read(mybytearray, 0, mybytearray.length); //System.out.println(mybytearray.length); os.write(mybytearray, 0, mybytearray.length); os.flush(); } os.close(); sock.close(); } catch(Exception e) { e.printStackTrace(); } </code></pre>
