Files downloaded from an applet are getting corrupted?

[Jacob_]

I'm trying to make an applet loader for my game. Once downloaded, the 3 .jar files it needs are the correct size, but they don't work. I opened them with a hex editor and found that some bytes are being changed to other bytes, seemingly at random. However, it isn't random because if I delete the files and have them download again, the same incorrect bytes are in the same places! It's really weird.

Here is the code.

1   2   3   4   5   6   7   8   9   10   11   12   13

URL url = new URL(urlString);                                     URLConnection conn = url.openConnection();                                     int len = conn.getContentLength();                                     downloadStream = new ProgressBarInputStream(conn.getInputStream(), updatePanel.progressBar, len);                                     String filePath = gamePath + "/" + urlString.replace("http://mydomain.net/game/", "");                                     FileOutputStream out = new FileOutputStream(filePath);                                     int bytes = 0;                                     while (bytes < len) {                                         out.write(downloadStream.read());                                         bytes++;                                     }                                     out.close();                                     downloadStream.close();

For one thing, it is best to buffer downloaded data when transferring data across the interwebz.

1   2   3

int buffer[] = new int[8192]; //buffer data 8KB at a time (or any other buffer rate you like) while(downloadStream.read(buffer) > 0)     out.write(buffer);

Other than that, your code looks fine to me.
