无法连接到RMI注册表 [英] Failed to connect to RMI registry

问题描述

我正在Ubuntu 12.04上运行activemq-5.9，可以说我是主动MQ的新手。

I am running activemq-5.9 on Ubuntu 12.04 and it would be fair to say that I am new to active MQ.

我怀疑我正在排队记录和而不是让它们出队，因此我正在研究使用JMX连接到我的活动MQ代理，并查看发生了什么。 Jconsole失败。

I suspect that I am queueing records and not de-queueing them, so I am looking into using JMX to connect to my active MQ broker and see what's going on. Jconsole fails.

这很困难，因为有关如何执行此操作的大多数文档都已过时，但是我终于开始运行activemq列表了。当我这样做时，它会抛出一个相当长的堆栈跟踪：

This is hard because most of the docs on how to do this is old, but I finally get down to running activemq list. When I do, it throws a rather lengthy stacktrace:

我配置错了什么？我没有防火墙规则。我想不到要寻找什么。

Is there still something I have configured wrong? I have no firewall rules. I can't think what else to look for.

推荐答案

这里没有无法检索RMI服务器存根。连接到RMI注册表失败。它可能根本无法运行，或者您正在寻找错误的主机或端口。

There is no 'failure to retrieve RMI server stub' here. There is a failure to connect to the RMI registry. Either it isn't running at all or you're looking in the wrong host, or port.
