Pessoal,
Estou seguindo a apostila FJ-28 da Caelum.
Estou terminando o capítulo 8, onde é inserida a validação utilizando o hibernate validator.
Até então estava tudo funcionando perfeitamente, exclusão, alteração e inserção. Depois de inseridas as anotations do validator, configurado o vraptor.xml e tudo mais que a apostila manda fazer, a validação funciona, e não consigo inserir uma música sem nome por exemplo, porém a exclusão não funciona mais.
O erro é o seguinte:
HTTP Status 500 -
