Hi,

I Have to Implement Captcha in my project.

For this I have downloaded source from http://sourcefourge.net/projects/simpleCatcha, which is a Captcha code generator and validator.

When I Place SimpleCapchaExample.jsp in directly into my application folder it works fine.
The Problem lies when I want to Place SimpleCapchaExample.jsp in /jsp/Login/ folder of my Application.
The Page Doesnot show any captcha image or i get a session variable
How should i ssolve this problem

SimpleCapchaExample.jsp

String c= (String)session.getAttribute(nl.captcha.servlet.Constants.SIMPLE_CAPCHA_SESSION_KEY) ;
String parm = (String) request.getParameter("captchafield");

out.println(parm + " ? " + c + ":");

if (c != null && parm != null) {
if (c.equals(parm)) {
out.println("<b>true</b>");
}else {
out.println("<b>false</b>");
}
}

Hello,

Maybe there is a problem in web.xml - try define captcha servlet's url-pattern like following /jsp/Login/Captcha.jpg

or try set url-pattern to /Captcha.jpg and use image definition
