我正在尝试使用我的Ubuntu机器上的JConsole工具连接到在不同机器上运行的远程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

我正在我的机器上运行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：

当我点击Connect按钮时,我得到例外说：

    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,我得到了主机的回复,没有任何问题.

解决方法:

请使用以下设置.我也遇到了同样的问题,但在设置不足后解决了

-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.

即使在这个设置之后它会要求不安全的连接请接受它然后你就能连接(它会给你错误和连接失败：java.lang.SecurityException：期望sun.rmi.server.UnicastRef2远程引用存根！).
