HttpServletResponse to get Http Status Code

[buntyindia]

Hi,

When we get request on server after processing that it writes back the response to client that also contains HTTP status code like 200 for Ok, 404 for page not found.

How can I have access to that in java, how can i retrieve that status code. Please help.

The Servlet itself (or any other class in charge) sets that status code itself; there
is no reason to retrieve it again from the response object, they can remember
that themselves if they want to. Why do you need that (redundant) functionality?
Any practical purpose?

kind regards,

Jos

Before setting that status I want to know the status so that on this basis of the code I can perform certain functionality.

I am using Filters for logging different kind of logs in this I need to know what is the status of HTTP response.

How about looking at the

<error-code>

and

<error-page>

elements in web.xml?

You may obtain the http status line with the following code:

httpStatusLine = urlConnection.getHeaderFields().get(null).get(0);

Having this status, you just have to extract the status code :

static final Pattern HTTP_STATUS_CODE_PATTERN=Pattern.compile("(\\d{3}) ");
Matcher matcher = HTTP_STATUS_CODE_PATTERN.matcher(httpStatusLine);
if (matcher.find()){
httpCode = matcher.group(1);
}
