computepi.java

用java RMI编写的一个远程计算平台

package client;

import java.math.BigDecimal;
import java.rmi.*;
import java.rmi.Naming;
import java.rmi.RMISecurityManager;

import compute.Compute;

public class ComputePi {
    public static void main(String args[]) {
    	System.setProperty("java.security.policy", ".\\client\\client.policy");
        if (System.getSecurityManager() == null) {
            System.setSecurityManager(new RMISecurityManager());
        }
        try {
            String name = "//162.105.146.95:3138/Compute";
            //Registry registry = LocateRegistry.getRegistry(args[0]);
            //Compute comp = (Compute) registry.lookup(name);         
            Compute comp = (Compute) Naming.lookup(name);
            Pi task = new Pi(10);
            BigDecimal pi = comp.executeTask(task);
            System.out.println(pi);
        } catch (Exception e) {
            System.err.println("ComputePi exception:");
            e.printStackTrace();
        }
    }
