All Superinterfaces:

javax.ejb.EJBLocalHome

public interface AccountHome

This interface is the home interface for the EJBean AccountBean, which in WebLogic is implemented by the code-generated container class AccountBeanC. A home interface may support one or more create methods, which must correspond to methods named "ejbCreate" in the EJBean.

Method Detail

create

public Account create(java.lang.String accountId,
                      double initialBalance,
                      java.lang.String type)
               throws javax.ejb.CreateException

This method corresponds to the ejbCreate method in the bean "AccountBean.java". The parameter sets of the two methods are identical. When the client calls AccountHome.create(), the container (which in WebLogic EJB is also the factory) allocates an instance of the bean and calls AccountBean.ejbCreate() For container-managed persistence, ejbCreate() returns a null, unlike the case of bean-managed persistence, where it returns a primary key. See section 9.4.2

Parameters:

accountID - String Account ID

initialBalance - double Initial balance

type - String Account type

Returns:

Account

Throws:

javax.ejb.CreateException - if there is an error creating the bean

java.rmi.RemoteException - if there is a communications or systems failure
