I am trying to setup a basic client/server, in which the server
returns a List of Row objects. My directory structure is...

C:\code\bin\
     server > Server.class
     client > Client.class
     data > Row.class
          RowCreator.class
          DefaultRowCreator.class

The RowCreator interface extends the rmi.Remote interface and has one
method, createRows. DefaultRowCreator is a concrete implementation of
RowCreator. Row is the data object which gets returned in a List by
RowCreator.

The server looks like....

RowCreator creator = new TableDataCreator();
RowCreator stub = (RowCreator)
UnicastRemoteObject.exportObject(creator, 0);
Registry registry = LocateRegistry.getRegistry();
registry.bind("row_creator", stub);

So I have the classes all compiled, and I open a command prompt to the
"bin" directory.

c:\code\bin> start rmiregistry
c:\code\bin> java -claspath . server.Server

I get the following...
java.rmi.ServerException: RemoteException occurred in server thread;
nested exception is:
java.rmi.UnmarshalException: error unmarshalling arguments; nested
exception is:
java.lang.ClassNotFoundException: data.RowCreator
at sun.rmi.server.UnicastServerRef.oldDispatch(UnicastServerRef.java: 385)

Caused by: java.rmi.UnmarshalException: error unmarshalling arguments;
nested exception is:
java.lang.ClassNotFoundException: data.RowCreator
at sun.rmi.registry.RegistryImpl_Skel.dispatch(Unknown Source)

Try:

start rmiregistry -J-classpath -J.
