Question

我正在尝试使用我的Ubuntu计算机上的JConsole工具连接到在不同计算机上运行的远程Java进程。

这就是我在远程机器上运行Java程序的方法：

sudo java -Dcom.sun.management.jmxremote.port = 51082 -Dcom.sun.management.jmxremote.authenticate = false -Dcom.sun.management.jmxremote.ssl = false -jar myfile.jar

我在我的机器上运行JConsole命令，如下所示：

jconsole -debug -J-Djava.util.logging.config.file = Logging.properties

这是我的Logging.properties文件：

handlers = java.util.logging.ConsoleHandler

sun.rmi.level=FINEST
.level = INFO

java.util.logging.ConsoleHandler.level = FINEST

java.util.logging.ConsoleHandler.formatter = \

java.util.logging.SimpleFormatter

// Use FINER or FINEST for javax.management.remote.level - FINEST is

// very verbose...

javax.management.level = FINEST

javax.management.remote.level = FINER

现在，在我的Jconsle UI上，我给出了以下属性：

enter image description here

当我点击Connect按钮时，我得到例外说法：

    FINER: [javax.management.remote.rmi.RMIConnector: jmxServiceURL=service:jmx:rmi:///jndi/rmi://my-remote-host:51082/jmxrmi] failed to connect: java.lang.SecurityException: Expecting a sun.rmi.server.UnicastRef2 remote reference in stub!
    java.lang.SecurityException: Expecting a sun.rmi.server.UnicastRef2 remote reference in stub!

This is the complete stacktrace of the exception as per logs:

我无法弄清问题在哪里。

更新

我可以连接到我的远程主机以获取给定端口：

telnet my_remote_host 51082

根据this link，我收到了来自主机的回复，没有任何问题。

Answer 1

请使用以下设置。我也面临同样的问题，但在设置低于设置后解决了

-Dcom.sun.management.jmxremote 
-Dcom.sun.management.jmxremote.authenticate=false 
-Dcom.sun.management.jmxremote.ssl=false 
-Dcom.sun.management.jmxremote.port=9704 
-Djava.rmi.server.hostname=172.18.137.35 
-Dcom.sun.management.jmxremote.rmi.port=970

请注意Djava.rmi.server.hostname和Dcom.sun.management.jmxremote.rmi.port。

即使在此设置之后，它会询问不安全的连接，请接受它，然后您就可以连接（它会给您错误和failed to connect: java.lang.SecurityException: Expecting a sun.rmi.server.UnicastRef2 remote reference in stub!）。

java.lang.SecurityException：期望存根中的sun.rmi.server.UnicastRef2远程引用
