Java EE (Java Enterprise Edition) General Discussion

I am new to this forum although I have been lurking around for while:)

I have a question about j_security_check.

I am working in Apache Tomcat server and I want to set up form based authentication. So I used j_security_check and I get an error 404 j_security_check page not found.

I am not sure how this is supposed to work.
1. Am I supposed to load the secured pages before I login and j_security_check should send me to the login.jsp page?
Or should I start with teh login.jsp page and if my login is incorrect, then I cannot load any page? (until I login correctly)

I always get 404 j_sedurity_check not found when I try to click submit button in login.jsp page and when I try to open other pages (even without login) I am able to open.

Can you please help me?

Should I register j_security_check in web.xml, if yes, please tell me how and give me a sample, please........


Here's my code:

web.xml

<security-constraint>
<display-name>SecurityConstraint</display-name>
<web-resource-collection>
<web-resource-name>STK</web-resource-name>
<url-pattern>/*.jsp</url-pattern>
<http-method>DELETE</http-method>
<http-method>GET</http-method>
<http-method>POST</http-method>
<http-method>PUT</http-method>
</web-resource-collection>
<auth-constraint>
<role-name>customer</role-name>
</auth-constraint>
<user-data-constraint>
<transport-guarantee>NONE</transport-guarantee>
</user-data-constraint>
</security-constraint>
<login-config>
<auth-method>FORM</auth-method>
<realm-name>file</realm-name>
<form-login-config>
<form-login-page>/login.jsp</form-login-page>
<form-error-page>/logi</form-login-config>
</login-config>
