Subject ClientAbortException: java.net.SocketException: Connection reset by peer: socket write error
Date Tue, 28 Jun 2005 03:32:56 GMT
Hello,

I got this exception and I don't know how to solve it, I have a web
application with a servlet which sends video with formats avi, mpeg,
and mov, it shows the video but the tomcat throws this exception:

and this is where the code fails:

 private void streamBinaryData(String urlstr,String
format,ServletOutputStream outstr, HttpServletResponse resp)
  {
        String ErrorStr = null;
        try{
          //find the right mime type and set it as contenttype
          resp.setContentType(getMimeType(format));
          BufferedInputStream bis = null;
          BufferedOutputStream bos = null;
          try{
              URL url	= new URL(urlstr);
              URLConnection urlc= url.openConnection();
              int length =urlc.getContentLength();
              resp.setContentLength(length);
              // Use Buffered Stream for reading/writing.
              InputStream in = urlc.getInputStream();
              bis = new BufferedInputStream(in);
              bos = new BufferedOutputStream(outstr);
              byte[] buff = new byte[length];
              int bytesRead;
              // Simple read/write loop.
              while(-1 != (bytesRead = bis.read(buff, 0, buff.length))) {
                bos.write(buff, 0, bytesRead);
              }
          } catch (Exception e) {
                e.printStackTrace();
                ErrorStr = "Error Streaming the Data";
                outstr.print(ErrorStr);
          } finally {
                if( bis != null ) {
                  bis.close();
                }
                if( bos != null ) {
                  bos.close();
                }
                if( outstr != null ) {
                  outstr.flush();
                  outstr.close();
                }
          }
        }
        catch(Exception e){
                e.printStackTrace();
        }
  }

I have read many forums but they do not explain in detail what the
problem is, some they say is a tomcat bug. Can anyone help me to
figure it out?

Thanks
