OneToMany Relationship problem - BatchUpdate
Hello
I am using NetBeans 5.5 and database is Oracle 9i.
There are two tables in my database
1. Department
Long DEPTID
VARCHAR DEPTNAME
2. Employee
Long EMPID
VARCHAR EMPNAME
LONG DEPTID
In the entity Department, I have:
@OneToMany(cascade = CascadeType.ALL, mappedBy="department")
private Set<Employee> empCollection;
public Set<Employee> getEmployeeCollection() {
return this.empCollection;
}
public void setEmployeeCollection(Set<Employee> empCollection) {
this.empCollection= empCollection;
}
In the Employee entity, I have
@ManyToOne
@JoinColumn(name = "DEPTID", referencedColumnName = "DEPTID", nullable= false)
private Department department;
public Department getDepartment() {
return this.department;
}
public void setDepartment(Department department) {
this.department = department;
}
In my Stateful session, I have:
public Long addEmployee(Long deptID, String empName) throws Exception
{
Department dept = em.find(Department.class, deptID);
Employee empl = new Employee();
empl.setName(empName);
empl.setDepartment(dept);
dept.getEmployeeCollection().add(empl);
em.persist(empl);
return empl.getEmpID();
}
In the Client application having the main method if I call the addEmployee method once, it works fine. But if i call this method in a loop then it works once or twice and after that i start getting the following exception:
java.lang.RuntimeException: org.jboss.tm.JBossRollbackException: Unable to commit, tx=TransactionImpl:XidImpl[FormatId=257, GlobalId=shaheen/22, BranchQual=, localId=22] status=STATUS_NO_TRANSACTION;

I have a container managed EntityManager in my session, maybe it is a transaction problem? The exception also says that parent key not found but the parent key exists in the database. Please help, I cannot find a solution.
Thanks
