The draft specification for JSR 160, Java Management Extension (JMX) Remote API 1.0, is available for public review. This JSR is to extend the JMX 1.0 specification, by adding client APIs. These APIs provide to any Java Manager discovery and access to JMX Agents abstracting the underlying protocol.
The JMX specification (JSR 3) currently provides the means to create Java based management agents, through standardized techniques for instrumentation, and standardized agent services. But it does not standardize the means to access these agents remotely.
This JSR will provide one mechanism for remote access by building on the JMX notion ofconnectors. A connector provides a remote client API for a JMX-based agent that is very similar to the local client API. This means that remote clients can call the familiarMBeanServer operations and can register for notifications using the NotificationListener interface.
This JSR will define what the remote client API looks like and how it behaves. It will also define standard transport protocols that an implementation of the JSR must support, so that different implementations will interoperate.
A standard format for JMX connector addresses will be introduced. Although this JSR will not invent a new discovery mechanism for finding connectors in a network, it will define how to advertise connectors in three existing systems: SLP, Jini, and JNDI.
Details of how servers find classes referred to by clients, and vice versa, will be specified.
This JSR depends on features introduced in the 1.2 version of the JMX API. Proxies simplify client-side programming. Per-MBean permissions provide fine-grained security control on the server side.
