sometimes getResponseCode throw a FileNotFoundExecption, (known
bug)
so catch it , and then use getHeaderField to get "Not Found 404"...

Objet : Reading error codes sent from servlet to applet
Hi!
First, I'm using Tomcat stand-alone with IBM JDK 1.3 on RH 6.2.
I'm developing an applet-servlet application. When I do POST
requests I want
the applet to pick up any errors from the servlet but I'm getting
IOExceptions when reading from the stream. Writing to the stream and
activating doPost() is not a problem. For example if I send a NOT
FOUND with
either sendError() or setStatus() on the stream then I cannot read
from the
stream in my applet, I get "stream closed". Is is possible for the
applet to
read these error codes or are they blocked by the browser? I have
also tried
in my applet to type cast the URLConnection to HttpURLConnection
because I
then could get the error code with getResponseCode() instead of
using
getHeaderField(), but this raises Exception as well, cannot find my
servlet.
I'm still new to servlets so I might be wrong about how to go about
error
control. Is it recommended to do error control this way with
communication
between applets and servlets? I know I can sent my error messages
with OK
but I curious about why the above doesn't work.
Any help or comments would be appreciated. Thanks.
Mads
P.S. Please reply to my e-mail address as well.
