Run remote Java program (Was: FTP remote commands)

Hello Mike,

This question would be better asked on the Java list.

Java supports a Remote Method Invocation (RMI) API.  It allows a Java
program on one system to invoke a Java program on another system and pass
objects between the programs. RMI is one of those Java APIs that is not
overly complex but is not trivial either and depends on proper set up in
order to work correctly.

You must write Java programs to use the RMI methods.  The rules for making
RMI work are:
 1. The class must be a subclass of the UnicastRemoteObject class.
 2. The class must implement an interface that describes the public methods.
 3. The interface must be a subclass of the Remote class.
 4. The interface must describe each public method.
 5. The interface methods must throw RemoteException.
 6. An RMI registry must be running on the server.
 7. An instance of the class must register with the registry.
 8. The client and the server must know on which TCP port to find the
registry.

The various Java Redbooks discuss RMI with examples.  However, RMI requires
Java at both ends.  If RMI is too complex or you don't want Java at the
AS/400 end then you must install a remote command server on the NT box and
send the appropriate incantation (e.g., java MyJavaClass) to the server.
You cannot use FTP because most implementations of FTP servers so not
support running host commands.

Simon Coulter.
