```
public abstract class RemoteInvocationSerializingExporter
extends RemoteInvocationBasedExporter
implements InitializingBean
```
Abstract base class for remote service exporters that explicitly deserialize RemoteInvocation objects and serialize RemoteInvocationResult objects, for example Spring's HTTP invoker.
Provides template methods for ObjectInputStream and ObjectOutputStream handling.

  - afterPropertiesSet
```
public void afterPropertiesSet()
```
    Description copied from interface: InitializingBean
    Invoked by the containing BeanFactory after it has set all bean properties and satisfied BeanFactoryAware, ApplicationContextAware etc.
    This method allows the bean instance to perform validation of its overall configuration and final initialization when all bean properties have been set.
    Specified by:
    afterPropertiesSet in interface InitializingBean
  - prepare
```
public void prepare()
```
    Initialize this service exporter.
  - getProxy
```
protected final Object getProxy()
```
  - createObjectInputStream
```
protected ObjectInputStream createObjectInputStream(InputStream is)
                                             throws IOException
```
    Create an ObjectInputStream for the given InputStream.
    The default implementation creates a Spring CodebaseAwareObjectInputStream.
    Parameters:
    is - the InputStream to read from
    Returns:
    the new ObjectInputStream instance to use
    Throws:
    IOException - if creation of the ObjectInputStream failed
  - doReadRemoteInvocation
```
protected RemoteInvocation doReadRemoteInvocation(ObjectInputStream ois)
                                           throws IOException,
                                                  ClassNotFoundException
```
    Perform the actual reading of an invocation result object from the given ObjectInputStream.
    The default implementation simply calls ObjectInputStream.readObject(). Can be overridden for deserialization of a custom wrapper object rather than the plain invocation, for example an encryption-aware holder.
    Parameters:
    ois - the ObjectInputStream to read from
    Returns:
    the RemoteInvocationResult object
    Throws:
    IOException - in case of I/O failure
    ClassNotFoundException - if case of a transferred class not being found in the local ClassLoader
  - createObjectOutputStream
```
protected ObjectOutputStream createObjectOutputStream(OutputStream os)
                                               throws IOException
```
    Create an ObjectOutputStream for the given OutputStream.
    The default implementation creates a plain ObjectOutputStream.
    Parameters:
    os - the OutputStream to write to
    Returns:
    the new ObjectOutputStream instance to use
    Throws:
    IOException - if creation of the ObjectOutputStream failed
  - doWriteRemoteInvocationResult
```
protected void doWriteRemoteInvocationResult(RemoteInvocationResult result,
                                             ObjectOutputStream oos)
                                      throws IOException
```
    Perform the actual writing of the given invocation result object to the given ObjectOutputStream.
    The default implementation simply calls ObjectOutputStream.writeObject(java.lang.Object). Can be overridden for serialization of a custom wrapper object rather than the plain invocation, for example an encryption-aware holder.
    Parameters:
    result - the RemoteInvocationResult object
    oos - the ObjectOutputStream to write to
    Throws:
    IOException - if thrown by I/O methods
