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 javax.naming.NamingException

Description copied from class: JndiRmiClientInterceptor

Fetches RMI stub on startup, if necessary.

Specified by:

afterPropertiesSet in interface InitializingBean

Overrides:

afterPropertiesSet in class JndiRmiClientInterceptor

Throws:

javax.naming.NamingException

JndiRmiClientInterceptor.setLookupStubOnStartup(boolean), JndiRmiClientInterceptor.lookupStub()

getObject

public java.lang.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.

Specified by:

getObject in interface FactoryBean

Returns:

an instance of the bean (should never be null)

getObjectType

public java.lang.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, e.g. on autowiring.

For a singleton, this can simply return getObject().getClass(), or even null, as autowiring will always check the actual objects for singletons. For prototypes, returning a meaningful type here is highly advisable, as autowiring will simply ignore them else.

Specified by:

getObjectType in interface FactoryBean

Returns:

the type of object that this FactoryBean creates, or null

ListableBeanFactory.getBeansOfType(java.lang.Class, boolean, boolean)

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.

Specified by:

isSingleton in interface FactoryBean

Returns:

if this bean is a singleton
