/**
* Service exporter which binds RMI services to JNDI.
* Typically used for RMI-IIOP (CORBA).
*
* You need to run "rmic" with the "-iiop" option to generate corresponding
* stubs and skeletons for each exported service.
*
* <p>Also supports exposing any non-RMI service via RMI invokers, to be accessed
* via {@link JndiRmiClientInterceptor} / {@link JndiRmiProxyFactoryBean}'s
* automatic detection of such invokers.
*
* <p>With an RMI invoker, RMI communication works on the {@link RmiInvocationHandler}
* level, needing only one stub for any service. Service interfaces do not have to
* extend {@code java.rmi.Remote} or throw {@code java.rmi.RemoteException}
* on all methods, but in and out parameters have to be serializable.
*
* <p>The JNDI environment can be specified as "jndiEnvironment" bean property,
* or be configured in a {@code jndi.properties} file or as system properties.
* For example:
*
* <pre class="code">&lt;property name="jndiEnvironment"&gt;
* &lt;props>
* &lt;prop key="java.naming.factory.initial"&gt;com.sun.jndi.cosnaming.CNCtxFactory&lt;/prop&gt;
