Hi! Just wanted to thank you for the amazing tutorial, been watching this in one shot from the begging breathlessly, by far the most thorough tutorial I have seen to date!

Just an idea.. I thought about a way to break the authentication so we can test the authentication exception message - put a breakpoint immediately after committing the new user to the db, go to the database and remove the newly created user manually (or just replace first/last name chars with wrong ascii .. so db retrieve and string cast will fail), then step over the breakpoint..

Awesome stuff thank you very much for such an informative tuto series. please explain how do this app using JSF managed bean clasess and session beans without using Spring. I am using Netbean's CRUD generation feature and then convert it to primefaces based JSF app. Anyway it would be nice if you can do tuto about how to create different access  privileges (admin, clerk, manager etc.) using those technologies using Glassfish.
thanks great work keep it up.

Hi Arthur,
in 33:30, why do you make the code dependent on Faces ?
Shouldn't the be decoupled from the GUI ?
Is it possible instead to throw an exception and let the presentation layer handle and display that appropriately?

[nikolastanar]

I've done tutorial number 18 also. Cannot get rid of the error. I think problem is in th md5 encoder, because i get strange values in my db (values are different than those in user entity when i do debug). Plus, every time i try to sign in, password value (stored in db) changes. Little help please...

How to fix the BAD CREDNTIALS issue, if so how; I have the same problem.

[Hepward]

why do you always delete @Override annotation? :)

Cannot authenticate after signing up. Says: "Bad credentials", thats exception message delivered on ui. I don't know why I cannot authenticate. User gets persisted to the database. I've checked, authentication manager is not null. Any clue?

Please help me

Cannot authenticate after signing up. Says: "Bad credentials", thats exception message delivered on ui. but when passwordfield is to simple plaintext hash="plaintext"/>) then it work...
but any one help

[danisida]

For the "Bad credentials" error, what I've done is move the encription lines:
     PasswordEncoder crypto = new Md5PasswordEncoder();
     crypto.encodePassword(userEntity.getPassword(), null)
 from UserEntity.setPassword to UserServiceImpl.createUser method. For some reason the UserEntity.setPassword method is invoked with the already hashed password and cause a password mistmatch.

 Hope it helps
