Firewall-friendly JMX Connector URL
-----------------------------------
Key: CAMEL-553
URL: https://issues.apache.org/activemq/browse/CAMEL-553
Project: Apache Camel
Issue Type: Improvement
Components: camel-core
Affects Versions: 1.3.0
Reporter: christian ohr
InstrumentationAgentImpl (or DefaultInstrumentationagent in the trunk) only
allows to set the JMX registry port, URL created is
service:jmx:rmi:///jndi/rmi://<host>:<registryPort>/jmxrmi.
However, when a connection is established, the remote objects are exchanged on
a different port. If this is not set, it's chosen by random, which is
particularly unhelpful if the instrumented Camel server is behind a firewall!
The appropriate URL is
service:jmx:rmi://<host>:<remotePort>/jndi/rmi://<host>:<registryPort>/jmxrmi.
Also see
http://blogs.sun.com/jmxetc/entry/connecting_through_firewall_using_jmx for
more details.
The easiest fix would be to define remotePort=registryPort+1 and use the new
URL in the createJmxConnector method. More flexible would be to have an
independent property and let the use choose which URL should be used.
