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.

Hi;
I am trying to get the captcha comment authentication to work with no
success.
I un- commented the <action> and <plug-in> elements from the
struts-config file and added my own roller-custom.properties with only
one key
(comment.authenticator.classname=com.octo.captcha.module.roller.JCaptcha
CommentAuthenticator)
When opening a single entry page I get a popup stating "there was a
problem retrieving the xml data Internal server error"
Looking at the logs I see a no class def problem. Probably the captcha
authenticator is trying to load the interface it implements and fails
for some reason.
Did anybody encounter this?
I looked and the comment servlets and the only thing I found that maybe
can impact this is the fact the they use:
Class clazz = Class.forName(name);
this.authenticator = (CommentAuthenticator)
clazz.newInstance();
Maybe more correct in a JEE environment to use:
Class clazz =
Thread,currentThread.getContextClassloader().loadClass(name);
this.authenticator = (CommentAuthenticator)
clazz.newInstance();
but I am not sure it fixes the problem cause I don't compile the roller
from the sourc so I couldn't fix this.
Any ideas?
