Reason:
This exception is thrown when you try to load an entity in hibernate with session.load() method and entity is not found. Exception trace look like this:
Hibernate: select department0_.ID as ID0_0_, department0_.NAME as NAME0_0_ from DEPARTMENT department0_ where department0_.ID=? org.hibernate.ObjectNotFoundException: No row with the given identifier exists: [hibernate.test.dto.DepartmentEntity#11] at org.hibernate.impl.SessionFactoryImpl$1.handleEntityNotFound(SessionFactoryImpl.java:375) at org.hibernate.proxy.AbstractLazyInitializer.checkTargetState(AbstractLazyInitializer.java:79) at org.hibernate.proxy.AbstractLazyInitializer.initialize(AbstractLazyInitializer.java:68) at org.hibernate.proxy.AbstractLazyInitializer.getImplementation(AbstractLazyInitializer.java:111) at org.hibernate.proxy.pojo.cglib.CGLIBLazyInitializer.invoke(CGLIBLazyInitializer.java:140) at hibernate.test.dto.DepartmentEntity$$EnhancerByCGLIB$$deac2c14.getName() at hibernate.test.TestHibernateEhcache.main(TestHibernateEhcache.java:21)
Solution:
The correct way to solve this problem is to use session.get() method. Get method will return null if entity is not found.
DepartmentEntity department = (DepartmentEntity) session.get(DepartmentEntity.class, new Integer(11)); //This will throw NullPointerException if entity is not found. System.out.println(department.getName());
Another solution is wrap the session.load() call in try catch clock and handle exception accordingly.

I had that same exception using get() method. Do you know what could make it?
I have a generic repository class that calls: getSessionFactory().getCurrentSession().get(getType(), id)
My domain class is something like follows:
public class MyClass{
private MySecondClass mySecondClass;
………….
}
When I get a MyClass object and try to use mySecondClass’s getter in it, I get that exception. That happens when mySecondClass object is supposed to be null but it is a proxyfied class named something javaassist.
