1. Where does the user request will be re-directed after the j_security_check servlet has finshed ?

See, if you have accessed a protected page say xxx.jsp, then j_security_check came in to action and ask the user his userid and password by displaying login page. If user is successfully authenticated, xxx.jsp will be served otherwise the default login-error page which is mentioned in web.xml will be displayed.

2. How do you know the user_name and password once the j_security_check is successful ?

Once the user is successfully authenticated and authorized, the j_security_check servlet will store the user data in side the request object.
The user name will be obtained by request.getRemoteUser() method.
request.isUserInRole("ADMIN"); method can be used whether the user is in a particular role or not.
Other methods useful are : request.getUserPrincipal(); request.getAuthType();

3. What is the difference between CC and BCC fields for sending mails ?

CC and BCC stands for Carbon copy and Blind Carbon copy. Now in BCC one can not know to whom the mail is sent in CC. Mail sent in BCC can not see other contacts.
c: stands for "carbon copy." Anyone listed in the Cc: field of a message will receive a copy of that message when you send it. All other recipients of that message will be able to see that the person you designated as a Cc: recipient has received a copy of the message. The Cc: field is useful in instances when you wish to share a message with someone but are not requesting that they reply or take any direct action in response.
bcc: stands for "blind carbon copy." This is similar to the Cc: feature, except that Bcc: recipients are invisible to all of the other recipients of the message (including other Bcc: recipients). The Bcc: field is useful in instances when you don't wish to share your recipients' email addresses with everyone who receives your message.
