500 Servlet Exception - Githubissues

Hi,
I copied kaptcha-2.3.jar in the resin 3.1.9, linux, java 1.6.0.14 in webapp.
I deployed the example war file and it works.
I copied kaptcha-2.3.jar in my lib webapp's directory (I have other libs
ofcourse)
and after many 500 Servlet Exception without print stack I try to use the
web.xml of example war file in my web application and I copied example page
too.
If I call it an error appears
