I have solved so:
1) Putting and hide input field in comment form:
sb.append("<input type=hidden name=\"mathAnswer\" value=\"");
sb.append(mathAnswer);
sb.append("\" />");
2) I have modified the authenticate method considering the request
parameter "mathAnswer" and no more the attribute session "mathAnswer". So
the condition to authenticate the user submitted answer is:
if (mathAnswerString != null && answer ==
Integer.parseInt(mathAnswerString)) {
authentic = true;
session.removeAttribute("mathAnswer");
session.removeAttribute("mathValue1");
session.removeAttribute("mathValue2");
}
Indeed I think that there is no needing to reset sessions attribute, as
(it seems to me that the real problem is that authenticate method won't
get information about the HTTP session.. - Could someone can figure out
why this happen? ).
One more question. Im not a real java programmer.. So I can figure out why
I get:
ERROR 2010-01-13 12:13:45,400 RollerContext:getAuthenticator - ERROR
creating authenticator, using default
java.lang.ClassCastException: org.rocsca.MathCommentAuthenticator cannot

.
Once I act on a submitted comment from roller backend.
Thanks in advance,
