Interfaces for remote access to JMX MBean servers. This package defines the essential interfaces for making a JMX MBean server manageable remotely. The specification of this functionality is completed by Part III of the JMX Specification, version 1.4 PDF document.
The JMX specification defines the notion of connectors.
A connector is attached to a JMX API MBean server and makes it
accessible to remote Java clients. The client end of a
connector exports essentially the same interface as the MBean
server, specifically the
A connector makes an MBean server remotely accessible through a given protocol. The JMX Remote API allows the use of different type of connectors:
JMXConnectorFactoryand, optionally, the Generic Connector (not part of this bundle, see note below).
Note: the optional packages implementing the optional part of the JMX Remote API are not included in the Java SE Platform but are available from the JMX Remote API Reference Implementation.
Typically, a connector server has an address, represented by the
JMXServiceURL. An address for the RMI Connector can look
JMXServiceURL, the first
specifies the RMI connector, while the second
specifies the RMI registry into which the RMI connector server
has stored its stub.
The example above shows only one form of address.
An address for the RMI Connector can take several forms,
as detailed in the documentation for the package
Typically, a connector server is associated with an MBean server either by registering it in that MBean server, or by supplying the MBean server as a parameter when creating the connector server.
A connector client is usually created by supplying the
JMXServiceURL of the connector server to connect to
When creating a connector client or server, it is possible to
supply an object of type
Map that defines
additional parameters. Each entry in this Map has a key that is
a string and an associated value whose type is appropriate for
that key. The standard keys defined by the JMX Remote API all
begin with the string "
jmx.remote.". The document
JMX Remote API lists these standard keys.
Every connection opened by a connector server has a string
identifier, called its connection id. This identifier
appears in the
JMXConnectionNotification events emitted by the connector
server, in the list returned by
getConnectionIds(), and in the value
returned by the client's
As an example, a connection ID can look something like this:
rmi://126.96.36.199 username 1
The formal grammar for connection ids that follow this convention is as follows (using the grammar notation from section 2.4 of The Java™ Language Specification):
ConnectionId: Protocol : ClientAddressopt Space ClientIdopt Space ArbitraryText ClientAddress: // HostAddress ClientPortopt ClientPort : HostPort
Protocol is a protocol that would
be recognized by
ClientAddress is the
address and port of the connecting client, if these can be
determined, otherwise nothing. The
HostAddress is the Internet address of
the host that the client is connecting from, in numeric or DNS
form. Numeric IPv6 addresses are enclosed in square brackets
HostPort is the
decimal port number that the client is connecting from.
ClientId is the identity of the
client entity, typically a string returned by
JMXPrincipal.getName(). This string must not contain
ArbitraryText is any additional
text that the connector server adds when creating the client id.
At a minimum, it must be enough to distinguish this connection
ID from the ID of any other connection currently opened by this
