Hi,
In question # 34 of the JavaRanch mock exam it says that the default action for a form is get.
I thought it was post???

Anyway I got 92% on the mock. Can anyone who's passed the certification compare this mock exam ( yes I know it's short ) to the real thing in terms of difficulty?
Thanks,
Terry

Nope, definitely GET. Of course in practice most people will use POST for a form, but the default is GET.

What if the question is "standard action for form" instead of "default action for a form"? Will the answer be "POST" instead of "GET"?

That's how I'd read it, but I'd say it was badly phrased.

Allan, I know where you are coming from I think it was fixed. I'll double check it.

"the login page must include a form with a POST to the URL �j_security_check� with a username sent as j_username and a password j_password"
I got question about "Form based authentication". How actually servlet container uses j_secrity_check,j_username,j_passwrd to do the authentication. please adivse. Thanks

(Note: We've changed topic now)
Form-based authentication is very similar to basic authentication, except that you define the page that collects the username and password rather than relying on the browser.
In BASIC the server returns "WWW-Authenticate: Basic realm="Default"" in the response header when user tries to access a protected resource. The browser then pops up the familiar window requesting username and password for the specified realm. These are then sent back to the server in a new request for the resource with "Authorization: Basic TXJQb2ludHlIYWlyOk1yUG9pbnR5SGFpcg==" or similar, where the encrypted string is is simply a Base64 encoding of "username:password". The server then decides whether to allow access or not.
With FORM-based authentication, when user tries to access a protected resource, the server goes to the login page specified in the deployment descriptor. The server can then use the username/password to authenticate the user.
The chapter in Jason Hunter's book has a good description, and there are examples online: http://www.servlets.com/jservlet2/examples/ch08/index.html
