uilding blocks of this bridge are based on standards well
known and used in both worlds: HTTP and JSON.

The agent part of jmx4perl can be found at www.jolokia.org. This site also
contains all relevan

 locally to the JMX
MBeanServer, and listens to HTTP requests whose results are translated into a
JSON representation. This reponse can be easily picked up by a Perl module,
L<JMX::Jmx4Perl> in our ca

ing the j4p agent servlet on
it. This works by using j4p.war as a JMX Proxy, which translates our
JSON/HTTP protocol on the frontside to JSR-160 JMX remote requests on the
backend and vice versa.

A d

em $content = $response->value() 

Return the content of this response, which is a represents the JSON response as
returned by the Java agent as a hash reference value. This is set only when C<is_ok> 

an C<java.lang:type=Memory>'s attribute C<HeapMemoryUsage> is a complex
value, which looks in the JSON representation like

 "value":{"init":0,"max":518979584,"committed":41381888,"used":33442568}

With these number you can restrict the size of the JSON structure
returned. C<maxDepth> gives the maximum nesting level of the JSON
object,C<maxObjects> returns the maximum number of objects
