RE: captcha comment authentication configuration problem
Hi;
You were right thanks.
I encountered another problem before being able to use the captcha
authentication.
The velocity context sent to the implementation class was null so
"context.get("ctxPath")" inside the authenticator implementation threw a
null pointer exception. (The http request/response that were sent were
ok - not null)
What I did was use "httpServletRequest.getContextPath()" instead of
using the velocity context and it seems to have done the work.
Thanks for the help
Guy.

that's not a problem with how the class is loaded and instantiated in
the code, the problem is that the interface for the CommentAuthenticator
was moved during some code updating.
In 2.3 it's at
org.apache.roller.ui.rendering.velocity.CommentAuthenticator
In 3.0 and moving forward it is at
org.apache.roller.ui.util.CommentAuthenticator
all you should need to do is update that class with the the correct
location of the interface and recompile and it should work.
