public abstract class RemoteInvocationSerializingExporter
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.

public void afterPropertiesSet()
InitializingBeanThis method allows the bean instance to perform initialization only possible when all bean properties have been set and to throw an exception in the event of misconfiguration.

protected ObjectInputStream createObjectInputStream(InputStream is)
throws IOException
The default implementation creates a Spring CodebaseAwareObjectInputStream.
is - the InputStream to read from
IOException - if creation of the ObjectInputStream failed
protected RemoteInvocation doReadRemoteInvocation(ObjectInputStream ois)
throws IOException,
ClassNotFoundException
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.
ois - the ObjectInputStream to read from
IOException - in case of I/O failure
ClassNotFoundException - if case of a transferred class not
being found in the local ClassLoader
protected ObjectOutputStream createObjectOutputStream(OutputStream os)
throws IOException
The default implementation creates a plain
ObjectOutputStream.
os - the OutputStream to write to
IOException - if creation of the ObjectOutputStream failed
protected void doWriteRemoteInvocationResult(RemoteInvocationResult result,
ObjectOutputStream oos)
throws IOException
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.
