Interface examples.ejb.basic.beanManaged.AccountHome

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 Index

o create(String, double)
This method corresponds to the ejbCreate method in the bean "AccountBean.java".
o findBigAccounts(double)
Finds all EJBeans with a balance greater than a given amount.
o findByPrimaryKey(String)
Attempts to find the EJBean with a given Primary Key from the persistent storage.

Method Detail

o create

public Account create(java.lang.String accountId,
                      double initialBalance) throws javax.ejb.CreateException, java.rmi.RemoteException
          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 bean-managed persistence, create() returns a primary key, unlike the case of container-managed persistence, where it returns a void.
Parameters:
accountID - String Account ID
initialBalance - double Initial Balance
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
