RE: Direct call to j_security_check when using form based authori zati on
Thank you for your answer. I understand what you mean, but I am afraid I did
not specify my problem enough.
I would like to have a login form (fast login) on my public page where a
visitor can directly insert username and password. When the client press the
login button I would like to send him to the correct page (which is
restricted) without forcing him to visit the login.jsp (the page specified
as form-login-page in the web.xml). This seems natural since he has
already added his login data once. If the client is trying to access a
restricted page without using the fast login, then it is of course desirable
that the container intercepts the call and shows the login form.
What I have tried to do is to attache the username and the password in the
http-parameter list (with post) when directing the user from the fast login
form to a restricted area, and then to automatically forward the call to the
j_security_check from the login.jsp if a password and a username is attached
to the http-parameter list. The problem is that the Orion web-server does
not accept the direct call to the j_security_check.
Does anyone have any ideas about how to solve this problem?
Below you´ll find my test login.jsp and the error message from the
web-browser.
Best regards,
Erik

Define an secure url (e.g. /secure/requestedLogin) which forces the user to
login (just as you described) and request it from a button or link on the
public page you want.
When the user isn't logged in yet the servlet container will intercept the
request and force the user to login remembering the requested url and
redirects the user to this original url after login.
From the destination page (your secure url) you can send a client side
redirect to the original (public) page or somewhere else (secure or
non-secure).

authorizati on
I am using form based authentication in my application. When
trying to
access a protected resource, the container automatically
prompts the login
form to the user, where he can fill in authentication info
(username and
password).
Code from login.jsp:
form method=POST action=j_security_check
input type=text name=j_username
input type=password name=j_password
/form
Here the Servlet-specification dictates that the action to be
called from
the login form must be j_security_check
RE: Direct call to j_security_check when using form based authori zati on
Erik: Try changing your snippet below to... jsp:forward page=%= j_security_check?j_username= + java.net.URLEncoder.encode(j_username) + j_password= + java.net.URLEncoder.encode(j_password) % / THE PROBLEM -- Notice the ? rather than the ; before the first parameter; the ? identifies the start of the query string and the ; is being interpreted as part of the servlet mapping (i.e. /j_security_check; rather than just j_security_check). If that doesn't work, try putting the username/password into request attributes when you submit from the public page and retrieve them in your login.jsp page to use as values for the form fields, and if those parameter values exist, auto-submit the login.jsp page. This will still pop-up the login.jsp when you try to get a restricted resource directly, but also allow you to login from various external locations. Hope that helps...
