使用jmx4perl和j4psh接管Jolokia

在ActiveMQ的API中，内置了Jolokia 。

可以使用jmx4perl来安装：

$ perl -MCPAN -e shell
Terminal does not support AddHistory.

cpan shell -- CPAN exploration and modules installation (v1.)
ReadLine support available (maybe install Bundle::CPAN or Bundle::CPANxxl?)

cpan[]> install JMX::Jmx4Perl
...
...
jmx4perl
========

jmx4perl is a command line utility for accessing Jolokia agents
(www.jolokia.org). It can be used for script based exploration
and easy inspection of the JMX space.

Install 'jmx4perl' ? (y/n) [y ]
....

其余的库可以自行安装
