Hi Brantley,
Thanks for replying.
I've tried to pass a wrapper to the filter's chain, here is the
wrapper's code:
import java.io.IOException;
import javax.servlet.http.*;
public class TestResponse extends HttpServletResponseWrapper {
private int statusCode;
public TestResponse(HttpServletResponse response) {
super(response);
}
public int getStatus() {
return statusCode;
}
public void sendError(int errorCode) throws IOException {
this.statusCode = errorCode;
super.sendError(errorCode);
}
public void sendError(int errorCode, String errorMessage) throws
IOException {
this.statusCode = errorCode;
super.sendError(errorCode, errorMessage);
}
public void setStatus(int statusCode) {
this.statusCode = statusCode;
super.setStatus(statusCode);
}
}
I hopped tomcat will use the wrapper's setStatus() method and then I
will be able to get the status code.
What actually happened is that sometimes the status code returned was 0
and sometimes 404 or 304. It seems tomcat used the wrapper's setStatus()
method only in part of the cases (maybe only when there was a problem
getting the page).
How does the byte count gives information on the status code ?
How do you get the byte count from the output stream ?

Yair,
I too would be interested in this. I wrote a logging filter that does
what you describe, but the best that I could come up with was a
response wrapper that was passed along the filter chain. In the
wrapper, I could set a status, thus guaranteeing that I would end up
with a status at the end. The wrapper extends
HttpServletResponseWrapper.
You may also find a wrapper useful because response sizes are not
always set either, at least in my experience. With the wrapper, you
can monitor the output stream to get a byte count.

Hello,
I'm trying to create a filter that will do the access logging for my
web application
(I would like to write the information directly to the database not
to a file).
I have a problem to get the status code of the response.
The filter receives a ServletResponse object that do not have a
getStatus() method.
Any idea ?
