RMI c.f. HTTP-tunneling

[achana chan]

Hi again !
R the two mutually exclusive ???
When would I use RMI over tunneling ???
Is tunneling the preferred way to invoke remote methods over the internet ???

RMI is the way big J2EE server systems work - it is the fastest IF everybody is on the same network.
HTTP "tunneling" is required if you have to go through firewalls. The emerging standard is to use XML-RPC or SOAP over port 80.

I am looking at both onsite (intranet) and off-site (www) access to the data. The latter is behind a fore wall.
Does this mean that I have to use RMI for the former and tunneling for the latter ?

AT the moment I am trying to :

import java.io.*;
public abstract class TunnelLiteClient extends BaseTunnelClient

javac cannot resolve symbol BaseTunnelClient.
I wonder whether j2sdk1.4 has got this package in java.io.* ???
