AMX is an API that exposes all of the Enterprise Server configuration, monitoring and JSR 77 MBeans as easy-to-use client-side dynamic proxies implementing the AMX interfaces. To understand the design and implementation of the AMX API, you can get started with this white paper.
Complete API documentation for AMX is provided in the Enterprise Server package.
The code samples in this section are taken from the package:
The Enterprise Server is based around the concept of administration domains. Each domain consists of one or more managed resources. A managed resource can be an Enterprise Server instance, a cluster of such instances, or a manageable entity within a server instance. A managed resource is of a particular type, and each resource type exposes a set of attributes and administrative operations that change the resource’s state.
Managed resources are exposed as JMX management beans, or MBeans. While the MBeans can be accessed using standard JMX APIs (for example, MBeanServerConnection), most users find the use of the AMX client-side dynamic proxies much more convenient.
Virtually all components of the Enterprise Server are visible for monitoring and management through AMX. You can use third-party tools to perform all common administrative tasks programmatically, based on the JMX and JMX Remote API standards.
The AMX API consists of a set of interfaces. The interfaces are implemented by client-side dynamic proxies, each of which is associated with a server-side MBean in the Domain Administration Server (DAS). AMX provides routines to obtain proxies for MBeans, starting with the DomainRoot interface (see http://glassfish.dev.java.net/nonav/javaee5/amx/javadoc/com/sun/appserv/management/DomainRoot.html).
The term AMX interface in the context of this document should be understood as synonymous with a client-side dynamic proxy implementing that interface.
You can navigate generically through the MBean hierarchy using the com.sun.appserv.management.base.Container interface (see http://glassfish.dev.java.net/nonav/javaee5/amx/javadoc/com/sun/appserv/management/base/Container.html). When using AMX, the interfaces defined are implemented by client-side dynamic proxies, but they also implicitly define the MBeanInfo that is made available by the MBean or MBeans corresponding to it. Certain operations defined in the interface might have a different return type or a slightly different name when accessed through the MBean directly. This results from the fact that direct access to JMX requires the use of ObjectName, whereas the AMX interfaces use strongly typed proxies implementing the interface(s).
