java rmi重新连接客户端问题
我正在尝试开发一个简单的服务器/客户端程序usrinjavarmi。到目前为止,一切似乎都很正常,但唯一的问题是,当客户端退出并尝试重新连接时,会出现以下异常:java rmi重新连接客户端问题,java,rmi,Java,Rmi,我正在尝试开发一个简单的服务器/客户端程序usrinjavarmi。到目前为止,一切似乎都很正常,但唯一的问题是,当客户端退出并尝试重新连接时,会出现以下异常: java.rmi.ServerException: RemoteException occurred in server thread; nested exception is: java.rmi.ConnectException: Connection refused to host: 192.168.x.y; nested

为什么服务器第二次拒绝连接
这是我的密码
服务器:
public static void main(String[] args) {
try {
Naming.rebind("ChatServer", new ChatServerImpl());
Naming.rebind("NotificationSource", nsource);
System.out.println("Chat Server is up and runnning!");
} catch (Exception e) {
System.err.println("Problem!!!!");
e.printStackTrace();
}
}
“聊天服务器”和“nsource”(nsource是静态的)是扩展“远程”接口的UnicastRemoteObject对象。(“ChatServer”和“NotificationInterface”)
客户
public static void main(String[] args) {
String url_ChatServer = "rmi://localhost/ChatServer";
String url_NotificationSource = "rmi://localhost/NotificationSource";
try {
ChatServer cs = (ChatServer) Naming.lookup(url_ChatServer);
NotificationSourceInterface ns = (NotificationSourceInterface) Naming.lookup(url_NotificationSource);
new Thread(new ChatClientImpl(cs,ns)).start();
} catch (Exception e) {
System.err.println("Problem ~Client");
e.printStackTrace();
}
}
我没有使用rmic,因为不再需要它(因为java 1.5)
thx如果您在查找中得到该信息,则注册表已关闭。如果让它调用远程方法,则其JVM已退出
