Hi, Is there a way to generate an entity with a custom class as id? Like: /** * Class that define the Id */ @Embeddable public class Code implements Serializable{     private Integer number;     private Integer year; } /** * My entity class */ @Entity public class Document{     @EmbeddedId     private Code code; } Posted by forums Original post: https://community.jboss.org/message/855351#855351
