Ai pessoal, será que alguém poderia me dar uma dica ? Estou usando o Hibernate e "do nada" começou a dar esse erro: (impl.SessionFactoryImpl 119 ) building session factory net.sf.hibernate.MappingException: could not i…

Esta é a única mensagem que você recebe em todo o stack trace? Isso ocorre quando o nome da classe do generator está vazia ou é inválido. Algum dos seus mapeamentos está incorreto.

Você precisa definir o generator-class como assigned nesses casos.

Hibernate com Oracle erro = could not instantiate id generator

Acho que o problema é que tenho 2 tabelas com chave String, e por isso não coloquei generator. Exemplo :

/** 
 * @hibernate.id
 *  name="sigla"
 * 	type="string" 
 *  column="sexo_sg" 
 */	
public String getSigla() {
	return sigla;
}

Ai vai o trace
