I have two entities: public class Employee { | ... | @ManyToOne | public Organization getPlaceOfWork() { | return placeOfWork; | } | public void setPlaceOfWork(Organization placeOfWork) { | this.placeOfWork = placeOfWork; | if(placeOfWork!=null){ | placeOfWork.getEmployees().add(this); | } | } | | } | | public class Organization { | ... | @OneToMany(fetch=FetchType.EAGER, mappedBy="placeOfWork") | public Collection<Employee> getEmployees() { | return employees; | } | public void setEmployees(Collection<Employee> employees) { | this.employees = employees; | } | } How can I cause Employees to be set their placeOfWork to null when Organization is removed (like database cascade)? And what should I do, if I want to delete Employees when Organization is removed? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3972723#...
