We met a problem. We use JAAS to authenticate the users of our web application. We developed a login module. When the login failed (for example, the user name is incorrect or the password is incorrect), we throws a LoginException. Could the message in the instance of LoginException be retrieved in the form error page? Thanks for your help very much.
