Hi!
I am trying to extract content from ServletInputStream:

ServletInputStream cont = request.getInputStream();
        StringBuffer sb = new StringBuffer();
        BufferedReader br = new BufferedReader(new InputStreamReader(cont));
        sb.append(br.read());
        System.out.println(sb.toString());
        System.out.println(request.getContentLength());

But i get:
-1
-1
Why can't it read it?

I would like to add:
what im trying to do, is to get the content when the user clicks on a
link to open the page (not by submitting it)

Hi,

I think that when they click on a link, which sends an HTTP GET request
to the webserver, there is no "content". When they do a submit, which
sends an HTTP POST (e.g., submitting a form), then there is "content"
which can be read.

Nearly ;-) There is only content that can be read, if there
is content being sent. If there is content, will be estimated
with the content-type. With a Content-type of
application/x-www-form-urlencoded (that will be sent if a
form is submitted using POST) I wouldn't expect data that can
be read from the stream, either. The data will be already read
by the surrounding ServletContext to enable use
request.getParameter(...)

But I might be wrong and you should just try it.

I personally* rate that advice as '10 stars' (out of ten).

( * In case anybody should be even the slightest bit
interested in my opinion of the matter. ;)
