public class JaxRpcPortProxyFactoryBean
extends JaxRpcPortClientInterceptor
implements FactoryBean

FactoryBean for a specific port of a JAX-RPC service. Exposes a proxy for the port, to be used for bean references. Inherits configuration properties from JaxRpcPortClientInterceptor.

This factory is typically used with an RMI service interface. Alternatively, this factory can also proxy a JAX-RPC service with a matching non-RMI business interface, i.e. an interface that mirrors the RMI service methods but does not declare RemoteExceptions. In the latter case, RemoteExceptions thrown by the JAX-RPC stub will automatically get converted to Spring's unchecked RemoteAccessException.

If exposing the JAX-RPC port interface (i.e. an RMI interface) directly, setting "serviceInterface" is sufficient. If exposing a non-RMI business interface, the business interface needs to be set as "serviceInterface", and the JAX-RPC port interface as "portInterface".

Method Detail

afterPropertiesSet

public void afterPropertiesSet()
                        throws ServiceException

Description copied from class: JaxRpcPortClientInterceptor

Prepares the JAX-RPC service and port if the "lookupServiceOnStartup" is turned on (which it is by default).

Specified by:

afterPropertiesSet in interface InitializingBean

Overrides:

afterPropertiesSet in class JaxRpcPortClientInterceptor

Throws:

ServiceException

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 FactoryBean is not fully initialized yet at the time of the call (for example because it is involved in a circular reference), throw a corresponding FactoryBeanNotInitializedException.

As of Spring 2.0, FactoryBeans are allowed to return null objects. The factory will consider this as normal value to be used; it will not throw a FactoryBeanNotInitializedException in this case anymore. FactoryBean implementations are encouraged to throw FactoryBeanNotInitializedException themselves now, as appropriate.

Specified by:

getObject in interface FactoryBean

Returns:

an instance of the bean (can be null)

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 one to check for specific types of beans without instantiating objects, for example on autowiring.

In the case of implementations that are creating a singleton object, this method 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 (a reference that can be cached)?

NOTE: If a FactoryBean indicates to hold a singleton object, the object returned from getObject() might get cached by the owning BeanFactory. Hence, do not return true unless the FactoryBean always exposes the same reference.

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
