With the registry running on the server machine, you can create and register a
RocketImpl
object:
package com.oozinoz.remote;
import java.rmi.*;
public class RegisterRocket
{
public static void main(String[] args)
{
try
{
// challenge!
Naming.rebind(
"rmi://localhost:5000/Biggie", biggie);
System.out.println("Registered biggie");
}
catch (Exception e)
{
e.printStackTrace();
}
}
}
If you copy this code to the same directory that the other files reside in, you can compile and
run it. The program displays a confirmation that the rocket is registered:
c:\rmi> javac com\oozinoz\remote\RegisterRocket.java
c:\rmi> java com.oozinoz.remote.RegisterRocket
Registered biggie
You need to replace the
//challenge!
line in the
RegisterRocket
class with code that
creates a
biggie
object that models a rocket. The remaining code in the
main()
method
registers this object. A description of the mechanics of the
Naming
class is outside the scope
of this discussion.
However, you should have enough information to create the
biggie
object that this code
registers.
CHALLENGE 11.3
Replace the
//challenge!
line with a declaration and instantiation of
the
biggie
object. Define
biggie
to model a rocket with a price of $29.95 and
an apogee of 820 meters.
Running the
RegisterRocket
program makes a
RocketImpl
object, specifically
biggie
, available on a server. A client that runs on another machine can access
biggie
if
the client has access to the
Rocket
interface and the
RocketImpl_Stub
class. If you are
