sorry the form should be as code:
<FORM method="POST" action="j_security_check"> <TABLE BORDER="2"><TR><TD>Login:</TD><TD> <INPUT type="text" name="j_username" size="16" maxlength="24" /><TD>Has?o:</TD><TD><INPUT type="password" name="j_password" size="16" maxlength="24" /><TD>Login:</TD><TD><INPUT type="submit" value="OK" /></TR></TABLE></FORM>
This is not how form authentication works. The container needs to display the form you specified as needed when accessing a secured resource.
Ok I know that it is the "usual" way. My question was how to put a form on a non-secured web page. Probably that's imposible to achieve easily but maybe someone knows how to do it ?
What you are trying to do is basically have custom authentication semantics sprayed into the standard Form Authentication mechanism.
You are better off keeping them seperate.
