Doubt in Entity Relationship Persistence

[Joe San]

Guys,

Consider the following example below where Department and Employee are entities with a relationship where in many employees belong to a department with a bidirectional directionality:

Department dep = em.find(Department.class, 10);
Employee emp = new Employee();
emp.setId(12);
emp.setName("Jothi");
emp.setDepartment(dep);
dep.addEmployee(emp);
em.persist(emp);

The question is when I call persist on the Employee instance, will the Department entity also be automatically be written to the database? Here the Employee is the owning side of the relationship and the Department is the inverse side of the relationship.

OOPS... Just thought about the cascade policies. But what would be the default?

I believe that the default for cascade is: not to cascade
