相关文档可以在这里找到:
The relevant documentation can be found here:
http://java.sun.com/javase/6/docs/technotes/guides/management/agent.html
使用以下参数启动您的程序:
Start your program with following parameters:
-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=9010
-Dcom.sun.management.jmxremote.rmi.port=9010
-Dcom.sun.management.jmxremote.local.only=false
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false
例如像这样:
java -Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=9010
-Dcom.sun.management.jmxremote.local.only=false
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false
-jar Notepad.jar
-Dcom.sun.management.jmxremote.local.only=false
不一定是必需的但没有它,它在 Ubuntu 上不起作用.错误将类似于这个:
-Dcom.sun.management.jmxremote.local.only=false
is not necessarily required
but without it, it doesn't work on Ubuntu. The error would be something like
this:
01 Oct 2008 2:16:22 PM sun.rmi.transport. customer .TCPTransport$AcceptLoop executeAcceptLoop
WARNING: RMI TCP Accept-0: accept loop for ServerSocket[addr=0.0.0.0/0.0.0.0,port=0,localport=37278] throws
java.io.IOException: The server sockets created using the LocalRMIServerSocketFactory only accept connections from clients running on the host where the RMI remote objects have been exported.
at sun.management.jmxremote.LocalRMIServerSocketFactory$1.accept(LocalRMIServerSocketFactory.java:89)
at sun.rmi.transport. customer .TCPTransport$AcceptLoop.executeAcceptLoop(TCPTransport.java:387)
at sun.rmi.transport. customer .TCPTransport$AcceptLoop.run(TCPTransport.java:359)
at java.lang.Thread.run(Thread.java:636)
参见 http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6754672
还要小心 -Dcom.sun.management.jmxremote.authenticate=false
使任何人都可以访问,但如果您只使用它来跟踪 JVM你的本地机器没关系.
Also be careful with -Dcom.sun.management.jmxremote.authenticate=false
which
makes access available for anyone, but if you only use it to track the JVM on
your local machine it doesn't matter.
更新:
在某些情况下,我无法访问服务器.如果我也设置此参数,则此问题已得到修复:-Djava.rmi.server.hostname=127.0.0.1
In some cases I was not able to reach the server. This was then fixed if I set this parameter as well: -Djava.rmi.server.hostname=127.0.0.1
