accountId

 public String accountId

balance

 public double balance

type

 public String type

AccountBean

 public AccountBean()

isModified

 public boolean isModified()

Returns whether the EJBean has been modified or not.

Returns:: boolean isDirty

setModified

 public void setModified(boolean flag)

Sets the EJBean's modified flag.

Parameters:: flag - Modified Flag

 public String id()

Returns the Primary Key identifying this EJBean.

Returns:: String Identification

ejbActivate

 public void ejbActivate() throws RemoteException

This method is required by the EJB Specification, but is not used by this example.

Throws: RemoteException: if there is a communications or systems failure

ejbPassivate

 public void ejbPassivate() throws RemoteException

This method is required by the EJB Specification, but is not used by this example.

Throws: RemoteException: if there is a communications or systems failure

setEntityContext

 public void setEntityContext(EntityContext ctx) throws RemoteException

Sets the EntityContext for the EJBean.

Parameters:: ctx - EntityContext
Throws: RemoteException: if there is a communications or systems failure

unsetEntityContext

 public void unsetEntityContext() throws RemoteException

Unsets the EntityContext for the EJBean.

Throws: RemoteException: if there is a communications or systems failure

ejbLoad

 public void ejbLoad() throws RemoteException

Sets the EJBean's modified flag to false.

Throws: RemoteException: if there is a communications or systems failure

ejbStore

 public void ejbStore() throws RemoteException

Sets the EJBean's modified flag to false.

Throws: RemoteException: if there is a communications or systems failure

ejbRemove

 public void ejbRemove() throws RemoteException

This method is required by the EJB Specification, but is not used by this example.

Throws: RemoteException: if there is a communications or systems failure

ejbCreate

 public void ejbCreate(String accountId,
                       double initialBalance,
                       String type)

This method corresponds to the create method in the home interface "AccountHome.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 home) allocates an instance of this EJBean 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

ejbPostCreate

 public void ejbPostCreate(String accountId,
                           double initialBalance,
                           String type)

This method is required by the EJB Specification, but is not used by this example.

Parameters:: accountID - String Account Identification; initialBalance - double Initial Balance; type - String Account type

deposit

 public double deposit(double amount)

Adds amount to balance.

Parameters:: amount - double Amount
Returns:: double balance

withdraw

 public double withdraw(double amount) throws ProcessingErrorException

Subtracts amount from balance.

Parameters:: amount - double Amount
Returns:: double Balance
Throws: ProcessingErrorException: if Amount > Balance

balance

 public double balance()

Returns current balance.

Returns:: double Balance

type

 public String type()

Returns account type.

Returns:: String Type
