ok, I'm not trying to do anything difficult here. I am downloading a file from a website, and then trying to write that stream to a file on my drive. I can get the stream of data from the website, and I can make the file, but the file is empty. Does anyone have any suggestions? BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream())); String line; line = in.readLine(); BufferedWriter out = new BufferedWriter(new FileWriter("c:\\TEMP\\images\\Image" + x + ".jpg")); out.write(line, 0, line.length()); -Thanks

I dont really see a problem with it. Did you try looping through whats in the buffer to see if it got the data? How big are the files your getting? Maybe you could try... out.write(line); out.close(); instead of giving it the file size??

Ok, this is a little closer... try{ BufferedReader br = new BufferedReader(fr); PrintWriter out = new PrintWriter( new BufferedWriter( new FileWriter( new File("tempImg.jpg")))); String buffer=""; while(!(null==(buffer=br.readLine()))){ out.println(buffer); } br.close(); out.close(); } catch(java.io.IOException ioe){ System.out.println(ioe.toString()); } But its still not correct. It converts the data somehow.. this would work fine for a text file, but not for images..

Thanks for responding. The files it is making are 0 bytes. I will have to try your suggestion later today to see if it will work. I have seen a program that makes jpg files with this code in it: JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(out); JPEGEncodeParam param = encoder. getDefaultJPEGEncodeParam(thumbImage); int quality = Integer.parseInt(args[4]); quality = Math.max(0, Math.min(quality, 100)); param.setQuality((float)quality / 100.0f, false); encoder.setJPEGEncodeParam(param); encoder.encode(thumbImage); But I'm not sure if I will need to use this or not.

Ok, this program reads the file into a byte array and then writes that into a file. No conversion problems!! try{ //Read from a File File file = new File("img1.jpg"); InputStream is = new FileInputStream(file); long length = file.length(); System.out.println("File Length: "+length); byte[] bytes = new byte[(int)length]; System.out.println("Length of ByteArray"+bytes.length); int offset = 0; int numRead = 0; while (offset = 0) { offset += numRead; System.out.println("NumRead: "+numRead); } System.out.println("Offset Length: "+offset); if (offset bytes.length) { throw new IOException("Could not completely read file "+file.getName()); } is.close(); //Creat ByteBuffer //ByteBuffer bbuf = ByteBuffer.allocate(10000); //bbuf.put((offset)0xFF); ByteBuffer bbuf = ByteBuffer.wrap(bytes); if(bbuf == null) { System.out.println("Byte Array is NULL."); } else { String s=bbuf.toString(); System.out.println("ByteBuffer State: "+s); } //Write to the file boolean append = false; File file2 = new File("tempImg.jpg"); if(file2 == null) { System.out.println("File 2 is null!"); } try { // Create a writable file channel FileChannel wChannel = new FileOutputStream(file2, append).getChannel(); // Write the ByteBuffer contents; the bytes between the ByteBuffer's // position and the limit is written to the file wChannel.write(bbuf); // Close the file wChannel.close(); } catch (IOException e) { } } catch(Exception fnfe){ System.out.println(fnfe.toString()); }

Sorry, forget to give that packages you need.. import java.io.*; import java.io.File; import java.io.FileWriter; import java.io.BufferedWriter; import java.util.*; import java.text.*; import java.nio.ByteBuffer; import java.io.IOException; import java.util.Properties; import java.util.StringTokenizer; import java.nio.channels.*; import java.nio.*; import java.nio.channels.FileChannel; This can be trimmed down a little too.

I have it figured out, I'll comment it and make some improvements and post the code on Fri 15th. Maybe add some error checking.
