Can you download classes of java in rmi ?
Java RMI supports dynamic code downloading and loading across the network. Since remote objects are specified only by an interface that extends Remote interface, the implementation class type is not needed to be known by the client, including the stub class type.
But to enable (provide the actual mechanism) class downloading, an http server must be available with the necessary class files (usually the stubs). You use the codebase property, written into the custom rmi serialization header, to specify where to go (URL) if the class is not available from the local classpath. See this documentation: http://java.sun.com/j2se/1.3/docs/guide/... .
GW: your understanding of Serialization is not quite right. When classes are marked as serializable (implements Serializable interface), the objects (and primitives) can be serialized as a stream of bytes (not as a byte array). You don't use DataInputStream and DataOutputStream, you use ObjectInputStream and ObjectOutputStream. They have methods like writeInt(), writeObject(), readInt(), readObject(), etc.

Java incorporates RMI classes into the default library under: java.rmi.*
