Re-Captcha not showing up in thickbox

[Rajkumar balakrishnan]

Hi guys,

I have re-captcha integrated with my Application and the issue is, when i open that jsp directly in address bar, the re-captcha is working properly, but if i call the same using a thickbox it's not working. Can anyone have any idea why this is happening?

the code i am using in JSP is :

<%@ page import="net.tanesha.recaptcha.ReCaptcha" %>
<%@ page import="net.tanesha.recaptcha.ReCaptchaFactory" %>

<%
     ReCaptcha c = ReCaptchaFactory.newReCaptcha("public_key", "private_key", false);
     out.print(c.createRecaptchaHtml(null, null));	
%>
