J_secrity_check

Question

Dear all,
i know in JAAS, when we use FORM base authentication,
the following code is needed:
<form method="POST" action="j_security_check" >
<input type="text" name="j_username">
<input type="password" name="j_password">
<input type="submit" name="j_security_check">
but just wondering, how does j_security_check know what is the valid user name or password ?
will it check against the database ? if so, where to define what table it should look up ?
what tells j_security_check what is the valid login ?

Answer 1

Hi,
basically these names refer to container managed resources and are defined in J2EE for Servlet authentication. Any J2EE compliant container knows how to resolve this information.
