I've got every time a lazy loading error for any property of a very simple entity : @Entity @Table(name = "DAY_OFF_TYPE") public class DayOffType extends AbstractEntity {         @Id       @GeneratedValue(strategy = GenerationType.IDENTITY)       @Column(name = "ID")       private Long id;       @Column(name = "KEY_LABEL", nullable = false)       private String keyLabel;         @Column(name = "PDF_TYPE", nullable = true)       private String pdfType;         @Column(name= "AVAILABILITY")       @Enumerated(EnumType.STRING)       private TypeOfAvailability availability;         public void setAvailability(TypeOfAvailability availability) {             this.availability = availability;       }         public TypeOfAvailability getAvailability() {             return availability;       }         public Long getId() {             return id;       }         public void setId(Long id) {             this.id = id;       }         public String getKeyLabel() {             return keyLabel;       }         public void setKeyLabel(String keyLabel) {             this.keyLabel = keyLabel;       }         public String getPdfType() {             return pdfType;       }         public void setPdfType(String pdfType) {             this.pdfType = pdfType;       }   } I lod that entity for a DAO, put it in a process variable, and trying to acces to it during an other task, and I've got an Exception when I'm trying to access to any property : [ERROR] org.hibernate.LazyInitializationException 42  - could not initialize proxy - no Session org.hibernate.LazyInitializationException: could not initialize proxy - no Session         at org.hibernate.proxy.AbstractLazyInitializer.initialize(AbstractLazyInitializer.java:167)         at org.hibernate.proxy.AbstractLazyInitializer.getImplementation(AbstractLazyInitializer.java:215)         at org.hibernate.proxy.pojo.javassist.JavassistLazyInitializer.invoke(JavassistLazyInitializer.java:190)         at mypackage.data.DayOffType_$$_javassist_13.getId(DayOffType_$$_javassist_13.java)         at mypackage.process.vacancy.VacancyProcessTest.testProcess(VacancyProcessTest.java:100) Any idea to solve that issue ?
