Olá, estou fazendo os exercicios da Apostila Caelum FJ-28 e me deparei com a seguinte exception que cheguei no capitulo de 10 - REST.

note The full stack trace of the root cause is available in the Apache Tomcat/7.0.5 logs.
Entendo que o problema está no objeto produto que já está no cache do hibernate está conflitando com o que estou tentando dar o update, mas como solucionar isso, onde será que fiz coisa errada, tto quebrando a cabeça e admito que meus conhecimento ainda são muito vagos, por isso preciso de ajuda.
Outra coisa reparei que a minha SESSION está iniciando quando carrego o tomcat, ela não teria que iniciar somente quando fosse requisitada pela aplicação?
