Interface examples.ejb.basic.containerManaged.AccountHome
- public interface AccountHome
- extends EJBHome
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(AccountPK)
- Given a Primary Key, refreshes the EJBean from
the persistent storage.
-
findDescOrderedBigAccounts(double)
- Finds all EJBeans with a balance greater than a given amount.
-
findNullAccounts()
- Finds all EJBeans with a type of 'null'.
-
findOrderedBigAccounts(double)
- Finds all EJBeans with a balance greater than a given amount.
create
public abstract Account create(String accountId,
double initialBalance,
String type) throws CreateException, 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 void, unlike the case of bean-managed
persistence, where it returns a primary key.
- Parameters:
- accountID - String Account ID
- initialBalance - double Initial balance
- type - String Account type
- Returns:
- Account
- Throws: CreateException
- if there is an error creating the bean
- Throws: RemoteException
- if there is
a communications or systems failure
- See Also:
- AccountBean
findByPrimaryKey
public abstract Account findByPrimaryKey(AccountPK primaryKey) throws FinderException, RemoteException
- Given a Primary Key, refreshes the EJBean from
the persistent storage.
- Parameters:
- primaryKey - AccountPK Primary Key
- Returns:
- Account
- Throws: FinderException
- if there is an error finding the bean
- Throws: RemoteException
- if there is
a communications or systems failure
- See Also:
- AccountBean
findAccount

- Finds an EJBean with a balance equal to a given amount.
Returns a single EJBean Account.
- Parameters:
- balanceEqual - double Test Amount
- Returns:
- Account
- Throws: FinderException
- if an error occurs while accessing
the persistent storage

a communications or systems failure

findBigAccounts
public abstract Enumeration findBigAccounts(double balanceGreaterThan) throws FinderException, RemoteException
- Finds all EJBeans with a balance greater than a given amount.
