Subject Re: [OT] Serializing HttpSession Object
Date Fri, 16 Apr 2004 06:34:58 GMT
I don't know you and there is not enough code here to tell how much you 
know, but do you know that you have to get the output stream to write to 
from wherever you are sending it to?  Thus, you might have something like:

       URL url = new URL(/* some destination */);
       HttpURLConnection connection = (HttpURLConnection)url.openConnection();
       ObjectOutputStream out = new 
       BufferedInputStream bis = new 
       Reader reader = new InputStreamReader(bis);
       StringBuffer sb = new StringBuffer("");

       int read;
       byte [] buffer = new byte[1024];
       while ((read = != -1) {
         sb.append(new String(buffer));

Is this helpful?  Why not use your logger to find out what is up?
