JCaptcha and Struts

[Timothy Sam]

Hi, has anyone used JCaptcha before? I'm trying to follow the tutorials on how to integrate this with Struts, but I can't seem to make it work... I haven't really used any of its features yet. All I did so far was...


1. Add the jcaptcha-all-1.0-RC3.jar in my WEB-INF\lib directory
2. Add the ehcache-1.2.1RC.jar in my WEB-INF\lib directory
3. Add the jcaptcha.tld in WEB-INF
4. Add the entry <plug-in className="com.octo.captcha.module.struts.CaptchaServicePlugin"/> in struts-config.xml

then I tried to include the TLD in my JSP like this...

<%@ taglib uri="/WEB-INF/jcaptcha" prefix="jcaptcha" %

Then I get the following errors...

HTTP Status 500 -
