在同一台电脑上运行通过,从另一台电脑运行客户端时出现问题!
客户端:
public class ExecuteEcho {
public static void main(String args[]) {
//System.setProperty(“java.rmi.server.codebase”,”http://192.168.1.154/E:/eclipse/workspace/rmi”);
/*
if (System.getSecurityManager() == null) {
System.setSecurityManager(new RMISecurityManager());
} */
try {
String name = “//” + args[0] + “/Compute”;
Compute comp = (Compute) Naming.lookup(name);
System.out.println(“please input the string to echoed”);
Echo toEcho = new Echo(Input.readString());
//comp.executeTask(toEcho);
System.out.println(comp.executeTask(toEcho));
} catch (Exception e) {
System.err.println(“Compute exception: ” +
e.getMessage());
e.printStackTrace();
}
}
}
服务器端:

String name = “//localhost/Compute”;
try {
Compute engine = new ComputeEngine();
Naming.rebind(name, engine);
System.out.println(“ComputeEngine bound”);
} catch (Exception e) {
System.err.println(“ComputeEngine exception: ” + e.getMessage());
e.printStackTrace();
}
