I have found the reason ... My code was the equivalent of :
URL url = new URL("http://localhost:8080/examples/snoop?param1=value1";);
HttpURLConnection connection = (HttpURLConnection)url.openConnection();
connection.setDoInput(true);
connection.setDoOutput(true);
connection.setUseCaches(false);
connection.setRequestProperty("Content-type",
"application/x-www-form-urlencoded");
PrintWriter out = new PrintWriter(connection.getOutputStream());
out.print("param2=value2");
out.close();
connection.connect();
connection.getInputStream().close();
And this throws an error. The problem is with the last line which works
fine with all other servlet engines but not Tomcat 3.3. If I change it
to :
connection.disconnect();
it now works fine. This probably means that when the connection is
closed it tries to close the underlying input stream and does not verify
if it is already closed (or something like this).
Thanks and sorry for the trouble.
