/**
 * Factory bean for RMI proxies from JNDI.
 * 
 * <p>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 {@link javax.rmi.PortableRemoteObject}.
 *
 * <p>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.
 *
 * <p>The JNDI environment can be specified as "jndiEnvironment" property,
 * or be configured in a <code>jndi.properties file or as system properties.
 * For example:
 *
 * <pre class="code"><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></pre>
