Erro JPA + EclipseLink

Jhonathan_Silva · Janeiro 4, 2017, 11:19am

Prezados, bom dia.

Estou tendo problemas ao tentar gravar informações no banco de dados, eu tenho um simples WS com JPA, EclipseLink e banco Postgresql. Eu consigo buscar dados e apresentalos como json no browser com metodos GET, porém estou presisando também gravar dados(POST) e neste momento recebe mensagem de erro:

A IDE é o Netbeans 8.1 com Glassfish 4.0.
