    public abstract class RmiBasedExporter

extends RemoteInvocationBasedExporter

Convenient superclass for RMI-based remote exporters. Provides a facility to automatically wrap a given plain Java service object with an RmiInvocationWrapper, exposing the `RmiInvocationHandler` remote interface.

Using the RMI invoker mechanism, RMI communication operates at the `RmiInvocationHandler` level, sharing a common invoker stub for any number of services. Service interfaces are not required to extend `java.rmi.Remote` or declare `java.rmi.RemoteException` on all service methods. However, in and out parameters still have to be serializable.

  1.2.5

  Returns:
    the RMI object to export

### invoke

    protected Object invoke(RemoteInvocation invocation,
                            Object targetObject)
                     throws NoSuchMethodException,
                            IllegalAccessException,
                            InvocationTargetException

  Redefined here to be visible to RmiInvocationWrapper. Simply delegates to the corresponding superclass method.

  Overrides:
    `invoke` in class `RemoteInvocationBasedExporter`
  Parameters:
    `invocation` - the remote invocation
    `targetObject` - the target object to apply the invocation to
  Returns:
    the invocation result
  Throws:
    `NoSuchMethodException` - if the method name could not be resolved
    `IllegalAccessException` - if the method could not be accessed
    `InvocationTargetException` - if the method invocation resulted in an exception
