Using reCAPTCHA with Java/JSP - Server returned HTTP response code: 403 for URL

[Jeff]

Hi,

I have seen a couple of people posting the same problem using the
reCAPTCHA with Java/JSP, but no response from anyone. I'm using the
same example code provided in the Using "reCAPTCHA with Java/JSP "
section to generate and validate the Captcha, but getting the
following error:

Error 500: net.tanesha.recaptcha.ReCaptchaException: Cannot load URL:
Server returned HTTP response code: 403 for URL: http://api-verify.recaptcha.net/verify

I'm testing the captcha using localhost, running under RAD 8.0. The
reCaptcha documentation mentioned localhost should work, so i'm
assuming using http://localhost domain is not the problem here. I
added a break point and found out the exception came from calling the
following method:

ReCaptchaResponse reCaptchaResponse =
reCaptcha.checkAnswer(remoteAddr, challenge, uresponse);

Can someone advise? Any help would be appreciated.

Thanks

Update your library, api-verify.recaptcha.net is obsolete.

The version I downloaded (recaptcha4j-0.0.7) looks to be the latest,
but the verify url is the old one.
I load the code in my development environment and changed the
HTTPS_SERVER and VERIFY_URL to the following, but still getting the
same exception.

public static final String HTTPS_SERVER = "https://www.google.com/
recaptcha/api";
public static final String VERIFY_URL = "http://www.google.com/
recaptcha/api/verify";

Error 500: net.tanesha.recaptcha.ReCaptchaException: Cannot load URL:

Server returned HTTP response code: 403 for URL: http://www.google.com/recaptcha/api/verify

Any advice?

thanks

Jeff

Going to that URL in a normal browser gives me the expected 200 page
telling me it wasn't given the correct data.

I suspect a problem with the server your code is running on blocking
outbound http(s) requests?

Hi,

In my case, the problem is when the API call getInputStream().

The only authorized URL on my server are :
- http://api-verify.recaptcha.net/verify
- http://www.google.com/recaptcha/api/verify

When calling the API, after a while, it's an other IP adress who
answer (exemple tx-in-f147.1e100.net) and it's blocked by our
firewall !!!

So, If I don't restrict HTTP on my server, it's working each time.

BUT, in my case, I have to restrict HTTP access on my server, so I can
open only URL to URL verify...

See you
