Class WebLogicServerTransactionManagerFactoryBean

java.lang.Object
  org.springframework.transaction.jta.WebLogicServerTransactionManagerFactoryBean

All Implemented Interfaces:

FactoryBean

public class WebLogicServerTransactionManagerFactoryBean

extends Object

implements FactoryBean

FactoryBean that retrieves the JTA TransactionManager for BEA's WebLogic application server version 7.0.

This class doesn't need be used with version 8.1 since for this version the regular JNDI lookup returns a ClientTransactionManagerImpl that can handle the necessary transaction management tasks.

Uses WebLogic TxHelper's static access methods to obtain the JTA TransactionManager.

Since:

1.1

Constructor Detail

WebLogicServerTransactionManagerFactoryBean

public WebLogicServerTransactionManagerFactoryBean()
                                            throws TransactionSystemException

This constructor retrieves the WebLogic TransactionManager factory class, so we can get access to the JTA TransactionManager.

Method Detail

getObject

public Object getObject()

Description copied from interface: FactoryBean

Return an instance (possibly shared or independent) of the object managed by this factory. As with a BeanFactory, this allows support for both the Singleton and Prototype design pattern.

If this method returns null, the factory will consider the FactoryBean as not fully initialized and throw a corresponding FactoryBeanNotInitializedException.

Specified by:

getObject in interface FactoryBean

Returns:

an instance of the bean (should not be null; a null value will be considered as an indication of incomplete initialization)

See Also:

FactoryBeanNotInitializedException

getObjectType

public Class getObjectType()

Description copied from interface: FactoryBean

Return the type of object that this FactoryBean creates, or null if not known in advance. This allows to check for specific types of beans without instantiating objects, for example on autowiring.

For a singleton, this should try to avoid singleton creation as far as possible; it should rather estimate the type in advance. For prototypes, returning a meaningful type here is advisable too.

This method can be called before this FactoryBean has been fully initialized. It must not rely on state created during initialization; of course, it can still use such state if available.

NOTE: Autowiring will simply ignore FactoryBeans that return null here. Therefore it is highly recommended to implement this method properly, using the current state of the FactoryBean.

Specified by:

getObjectType in interface FactoryBean

Returns:

the type of object that this FactoryBean creates, or null if not known at the time of the call

ListableBeanFactory.getBeansOfType(java.lang.Class)

isSingleton

public boolean isSingleton()

Description copied from interface: FactoryBean

Is the bean managed by this factory a singleton or a prototype? That is, will getObject() always return the same object?

The singleton status of the FactoryBean itself will generally be provided by the owning BeanFactory; usually, it has to be defined as singleton there.

Specified by:

isSingleton in interface FactoryBean

Returns:

if this bean is a singleton
