> I tried using Jolokia to browse the JSON view of JMX for ActiveMQ. Things=
 generally worked great, however the browseMessages() function causes issue=
s with the Jolokia JSON marshaller - it seems we return beans which are not=
 really usable as is. Not sure how easy this is to fix...
> NOTE the browse() works fine; I wasn't sure if all bean properties were p=
roperly exposed in the CompositeData browse() function - so not sure how bi=
g a deal not having browseMessages() is...

ning ActiveMQ and jolokia servlet such as with a URL like:=20
