Hi
I am getting the "org.hibernate.LazyInitializationException: could not initialize proxy - no Session" error while running my application:
I am using the Restful Webservices in GlassFish application server. I configured the Hibernate properties in the persistence.xml file. (GlassFish App server + Hibernate + Restful Webservices(jersey)).
I am using the Lazy loading.
Assume these is the situation:
I have Employee object and Department object.
The department object is declared as the member variable in the Employee object.
Public class Employee {
public int empno;
public
String empName;
public Department department;
public void setDepartment(Department dept){
//......
//......
//do something
}
@NotNull
@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "XYZ")
public Department getDepartment(){
//......
//......
//do something
}
//setter and getting for each methods
}
public class Department {
//......
//......
}
i am getting this Employee object using EntityManger find method .
I got the employee object and if i exeucte the getEmpNo oir getEmpName , i am getting the value.
but if i try to get the Department(while running the getDepartment method),
I am getting this
"org.hibernate.LazyInitializationException: could not initialize proxy - no Session"
Please could you explaing me , where is the problem and which one causing the problem.
