well the session beans are supposed to represent ur business processes/flows/logic, the entity beans represent the entities which make up ur business.

so lets say if u have business process which invloves registering a customer, u might wanna have a method "sessionbean.registerCustomer()" which takes various parameters/attributes (as serialised object) which represents a customer like name, age, gender etc.

so ur code cud look somethin like this

public void registerCustomer(Customer cust){

custEntity.setName(cust.getName());
custEntity.setAge(cust.getAge());
custEntity.setGender(cust.Gender());

}

hope this helps

Kapil:

I guess the example u have given is for a stateless
session bean as u've put all the entity calls in a
single session bean method implementation.
