Broken @ManyToOne reference

Hi, I have objects of type A belonging to objects of type B, defined as follows: @MappedSuperclass public abstract class A { @Id @ManyToOne(fetch = FetchType.EAGER, cascade=CascadeType.ALL, optional=false) private B b; @Id @Column(length = 36) private String stringId

Occasionally slow requests in load testing

" /> <persist serialization="false" /> <cascade-persist always="auto" on-persist="false" on-commit="true

Performance tuning, best practices

serialization="false" /> <cascade-persist always="auto" on-persist="false" on-commit="true" /> <dirty

Weird behaviour with enhanced classes and embedded entities

;     @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER)     private List

Connection is closed Caused by: java.io.EOFException

" /> <cascade-persist always="auto" on-persist="false" on-commit="true" /> <dirty-tracking arrays

LifeCycle Event with Embeddable classes

Hello, is there a way that lifecycle events like prepersist or preupdate are also fired for embeddable classes, not just for entities? My case looks as follows: @Entity public class Foo { @Id @GeneratedValue private Long id; private String description; @OneToMany(cascade

List always null

", cascade = CascadeType.PERSIST)     private List<Noticia> noticias; I'm trying to save an object
