请教各位大侠关于使用RMI中出现的错误：java.rmi.ConnectException: Connection refused to host: 127.0.0.1; nested exception

[yxf718]

我在使用RMI时，RMIserver 放在Linux上，用client 进行远程方法调用时它抛出
java.rmi.ConnectException: Connection refused to host: 127.0.0.1; nested exception is:
java.net.ConnectException: Connection refused: connect

但是rmiserver放在NT下就没问题。
程序在tring url = "rmi://192.168.0.230:1099/";
Object o = Naming.lookup(url + "rmiadmin");
后得到的rmi 远程对象o我打印
System.out.println("rmi ......." + o.toString());
其打印结果为：
rmi .......RMIAdmin_Stub[RemoteStub [ref: [endpoint:[127.0.0.1:32780](remote),objID:[c2ea3f:f2eea04781:-8000, 0]]]]
我觉得在lookup后就有问题
请各位高人指点，不然我过年要加班了。谢谢！！！！！！！！
如解决问题在加分

要用到策略文件
//启动注册表
rmiregistry -J-Djava.security.policy=registerit.policy
//启动server
java -Djava.security.policy=registerit.policy rmiserver
//启动client
java -Djava.security.policy=registerit.policy rmiclient

registerit
grant{
permission java.security.AllPermission;
}
//你运行的时候查一查运行参数

编写策略文件，添加运行参数！

[yxf718]

不行，但我改动linux的/etc/hosts 文件就可以了

你的Ｌｉｎｕｘ有防火墙，端口不允许连接。
