Olá
Estou tentando acessar um serviço remoto (RMI + Spring) que carrega uma coleção de objetos a partir de um banco de dados (Hibernate), mas tá sempre dando o seguinte erro
org.springframework.remoting.RemoteAccessException: Could not access remote service [rmi://10.50.11.100:1099/PublicacaoJuridicaRemoteService]; nested exception is java.rmi.UnmarshalException: error unmarshalling return; nested exception is:

Suspeitando que fosse problema com proxy do hibernate (e no desespero), tentei transformar a coleção retornada em uma coleção de DTOs (não mapeados no banco de dados) copiando as propriedades dos beans originais, mas não deu jeito. Acredito que por conta do bean possuir muitas associações que provavelmente também sejam retornadas como proxy.
Aguardo socorro…
