WLS 5.1 w/sp8 garbeling binary files when uploaded.

Question

I have implemented multiple methods of handling file uploads in servlets.
          I have tried the Marsh:
          http://sourceforge.net/projects/marsh/
          and the Oreilly com.oreilly.servlet:
          http://www.servlets.com/cos/index.html
          helper libraries as well as my own code, yet I still have the same problems.
          For some reason some bytes in binary files are being converted to ascii '?'s
          instead of the proper bytes. All uploaded files from all three
          implementations contain the same error, yet no bugs are listed in any of
          them (even Weblogic.)
          I am running WLS 5.1 SP8 on Windows and Linux and am having the same errors
          on both. If you might be thinking it's the way I'm writing the file then
          here is how I am outputing (once I get an input stream from the
          HttpServletRequest).
          /* Code snippet */
          x = myinput_stream.read();
          while(x >= 0) {
          myfile_writer.write(x);
          x = myinput_stream.read();
          myfile_writer.close();
          /* End code snippet */
          If you know how to fix this or you have gotten WLS to upload binary files at
          all then please reply and let me know.
          

Answer 1

I'll try that and then let you know....
