All Implemented Interfaces:

public class JndiRmiProxyFactoryBean
extends JndiRmiClientInterceptor
implements FactoryBean

Factory bean for RMI proxies from JNDI. Typically used for RMI-IIOP (CORBA), but can also be used for EJB home objects (for example, a Stateful Session Bean home). In contrast to a plain JNDI lookup, this accessor also performs narrowing through PortableRemoteObject.

With conventional RMI services, this invoker is typically used with the RMI service interface. Alternatively, this invoker can also proxy a remote RMI 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 RMI stub will automatically get converted to Spring's unchecked RemoteAccessException.

The JNDI environment can be specified as jndiEnvironment property, or be configured in a jndi.properties file or as system properties. For example: 

 <property name="jndiEnvironment">
         <props>
                 <prop key="java.naming.factory.initial">com.sun.jndi.cosnaming.CNCtxFactory</prop>
                 <prop key="java.naming.provider.url">iiop://localhost:1050</prop>
         </props>
 </property>

Method Detail

afterPropertiesSet

public void afterPropertiesSet()
                        throws NamingException
Description copied from class: JndiRmiClientInterceptor
Fetch the RMI stub on startup, if necessary.

Specified by:
afterPropertiesSet in interface InitializingBean
Overrides:
afterPropertiesSet in class JndiRmiClientInterceptor
Throws:
NamingException
See Also:
JndiRmiClientInterceptor.prepare()

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
See Also:
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

FactoryBean.getObject()
