Jolokia is a fresh way of accessing JMX MBeans remotely. It is different from JSR-160 connectors, as it is an agent based approach that uses JSON over HTTP for its communication. It provides new features for JMX remoting: bulk requests allow for multiple JMX operations with a single remote server roundtrip, there is a fine-grained security mechanism for restricting JMX access on specific JMX operations, JSR-160 proxy mode, and history tracking, to name a few. Jolokia's origins are in jmx4perl. Client bindings in addition to Perl have already been added, and more are planned.
