Glassfish JDBCRealm Login Exception

I have a JDBCRealm setup in glasfish 3.1 with oracle11. My web app authentication works fine, but now I'd like to be able to react if someone fails to login 3 times in a row. Looking at my server log I can see that every time the login fails an exception is logged :

WARNING: WEB9102: Web Login Failed:
com.sun.enterprise.security.auth.login.common.LoginException: 
Login failed: Security Exception

Do you guys know any way of catching it programmatically in my java code? I tried googling it, but to no avail.

Or maybe you know a better solution altogether? Please share.

Thanks, Damo

UPDATE: I need to re-phrase the question (or explain the situation properly). Every time authentication fails I want to log it in my database. To do that I need the username, timestamp, etc. Every time authentication fails the system will check failures count and if it's more than 3 it will lock the user's account. So, I could do it in my loginerror.jsp, but I need the username. Can't find it anywhere :). So far I experimented with a filter, but it appears that you can't filter on j_security_check url-patter (at least not in glassfish 3.1). So really, the main issue here is getting the username of the person that failed the login passed to loginerror.jsp (in any form: attribute, parameter, whatever). Will go and experiment with some java script and form submission.. hehe. Thanks.

Solution

  • You can only catch it if you take the login in your hands. Instead of submitting the form to j_security_check, you need to submit to a servlet which uses HttpServletRequest#login().

    try {
    request.login(username, password);
} catch (ServletException e) {
    // Handle.
}
