## Interface examples.ejb.basic.containerManaged.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.

##

create(String, double, String)
  This method corresponds to the ejbCreate method in the bean "AccountBean.java".
findAccount(double)
  Finds an EJBean with a balance equal to a given amount.
findBigAccounts(double)
  Finds all EJBeans with a balance greater than a given amount.
findByPrimaryKey(String)
  Given a Primary Key, refreshes the EJBean from the persistent storage.
findNullAccounts()
  Finds all EJBeans with a type of 'null'.

##

create

    public Account create(java.lang.String accountId,
                          double initialBalance,
                          java.lang.String type) 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 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
  See Also:
    AccountBean

findByPrimaryKey

    public Account findByPrimaryKey(java.lang.String primaryKey) throws javax.ejb.FinderException, java.rmi.RemoteException

Given a Primary Key, refreshes the EJBean from the persistent storage.
  Parameters:
    `primaryKey` - Primary Key
  Returns:
    Account
  Throws:
    javax.ejb.FinderException - if there is an error finding the bean
    java.rmi.RemoteException - if there is a communications or systems failure
  See Also:
    AccountBean

findAccount

    public Account findAccount(double balanceEqual) throws javax.ejb.FinderException, java.rmi.RemoteException

Finds an EJBean with a balance equal to a given amount. Returns a single EJBean Account.
  Parameters:
    `balanceEqual` - double Test Amount
  Returns:
    Account
  Throws:
    javax.ejb.FinderException - if an error occurs while accessing the persistent storage
    java.rmi.RemoteException - if there is a communications or systems failure
  See Also:
    AccountBean

findBigAccounts

    public java.util.Enumeration findBigAccounts(double balanceGreaterThan) throws javax.ejb.FinderException, java.rmi.RemoteException

Finds all EJBeans with a balance greater than a given amount. Returns an Enumeration of found EJBean Accounts.
  Parameters:
    `balanceGreaterThan` - double Test Amount
  Returns:
    Enumeration of Account
  Throws:
    javax.ejb.FinderException - if an error occurs while accessing the persistent storage
    java.rmi.RemoteException - if there is a communications or systems failure
  See Also:
    AccountBean

findNullAccounts

    public java.util.Enumeration findNullAccounts() throws javax.ejb.FinderException, java.rmi.RemoteException

Finds all EJBeans with a type of 'null'.
  Returns:
    Enumeration of Account
  Throws:
    javax.ejb.FinderException - if an error occurs while accessing the persistent storage
    java.rmi.RemoteException - if there is a communications or systems failure
  See Also:
