Presentation JMX on Capsaicin

Jolokia is a JMX-HTTP bridge giving an alternative to JSR-160 connectors. It is an agent based approach for remote JMX access with support for many platforms. In contrast to standard JSR 160 connectors, the communication between client and agent goes over HTTP where the payload is represented in JSON. In addition to basic JMX operations Jolokia enhances JMX remoting with unique features like bulk requests or fine grained security policies.
