Direct Known Subclasses:

BeanManagedServiceBean, ContainerManagedServiceBeanBase

public abstract class ServiceBean

extends SessionBeanImpl

BaseClass for Application Module Service Session Bean. Service beans aggregate an application module for exposing any business logic as a session bean.

Subclasses must provide a TransactionHandlerFactory implementation for associating the appmodule transaction with the bean transaction.

protected void createApplicationModule(java.lang.String amDefName,
                                       java.lang.String configName)
                                throws javax.ejb.CreateException

Convenience method for creating the aggregated application module instance using a LOCAL mode configuration.

Parameters:

amDefName - Fully qaulified appmodule definition name

configName -

createApplicationModule

protected void createApplicationModule(java.lang.String amDefName,
                                       java.util.Hashtable initialContextEnv)
                                throws javax.ejb.CreateException

Convenience method for creating the aggregated application module instance using the jndi environment properties.

Parameters:

amDefName - Fully qaulified appmodule definition name

initialContextEnv - The initial context environment used to create the aggregated appmodule in local mode.

createApplicationModule

protected void createApplicationModule(java.lang.String amDefName)
                                throws javax.ejb.CreateException

Convenience method for creating the aggregated application module instance. This method creates the the aggregated appmodule.

Parameters:

amDefName - Fully qaulified appmodule definition name

postApplicationModuleCreate

protected void postApplicationModuleCreate()

Called after creating the appmodule. Subclasses can extend this method to perform other initialization after the appmodule is created.

useDataSource

public void useDataSource(java.lang.String dataSourceName)

Set the JNDI name of the dataSource used for acquiring the jdbc connection. JDBC connection is acquired when the transaction is started

Parameters:

dataSourceName - The JNDI name of the dataSource. For OC4J this should be ejb-location of datasource defined in data-sources.xml.

connectToDataSource

protected void connectToDataSource()
                            throws JboException

disconnectFromDataSource

protected void disconnectFromDataSource()
                                 throws JboException

Releases the jdbc connection by acquired by #connectToDataSource().
