Subject j_security_check error
Date Sun, 01 Dec 2013 17:47:25 GMT
I’m using Tomcat and a MySQL database that contains
usernames/passwords/roles for form-based authentication.  Logging in with
correct username/password successfully directs to index.jsp (from
login.jsp).  Logging in with incorrect username/password successfully
directs to error.jsp (from login.jsp).  However, an unsuccessful login
followed by attempting to login with the correct username/password leads to
an HTTP Status 404 j_security_check error that says the requested resource
is not available.  Does anyone know what may be wrong?  Here are the details
of my configuration.

 

Software

 

-Windows 7

-MySQL 5.6 

-Tomcat 7.042
