MBeans for
stable resources
In this chapter,we will discuss the simplest type of MBean:the Standard MBean.
You created this type of MBean in chapter 2.Standard MBeans are intended for
resources that have well-known,stable interfaces.This chapter shows how you
can use Standard MBeans to configure application resources (a log utility and
application properties)and to break applications into components.If you need
the quickest way to implement a resource,the Standard MBean is for you.Stan-
dard MBeans expose a resource with an explicitly declared management inter-
face that is unchanging.

Standard MBeans
By far the most straightforward type of MBean to create,standard MBeans are a logi-
cal starting place for our voyage into the world of JMX.In this chapter,we will begin
by defining a management interface,then we will lookat the design patterns we
must use when building standard MBeans.Next,we will discuss some of the issues
involved when using inheritance among standard MBean classes.

Standard MBean descriptions
MX4J provides some extension to the JMX specification, some transparent with respect to MBeans or applications portability across JMX implementations, and some that instead ties your MBeans or applications to the MX4J implementation.

Managing Existing MBeans using SNMP
Existing standard or dynamic MBeans can be rendered manageable by generating a JMX agent for them, using ManageEngine JMX Studio. The management information contained in them is packaged as model MBean with an XML file, which has SNMP descriptors. It is registered with the MBean server. This opens the door for access to the management information via SNMP. The user is freed from the hassle of writing any Java code.
|
|
Using MBean Notifications
All WebLogic Server MBeans implement the javax.management.NotificationBroadcaster interfaces, which means they can emit standard JMX notification types.
|
|
WebJMXTag Library Project
While it's true that the JMX reference implementation contains an HTMLAdaptor implementation which already provides a simple data driven HTML interface for JMX MBeans, that interface is by it's nature limited to the information which can coded into the MBeandefinition. The WebJMX Tag library allows the developer to create a sharp looking HTML interface for JMX Mbeans without trying to code presentation logic into the MBeandefinition. The WebJMX tag allows a developer to use MVC design principals in order to separate presentation details from business logic.

J2EE Application Management: The Power of JMX
Enterprise adoption of J2EE as the strategic architecture for server-based applications is on the rise. Increasingly, mission-critical applications are being built and deployed on J2EE infrastructures. This trend is driving demand for better administration, monitoring and management of J2EE applications as well as the underlying network and systems infrastructure. J2EE based solutions will need to deliver on the management needs of large enterprises to be successful. An emerging standard, Java Management Extensions (JMX), will be essential to meeting these needs for J2EE applications.

Working with Management Beans
Pramati Server's Management Console complies with the Java Management Extensions (JMX) specifications and the JSR 77 (the Java specification for J2EE Server Management) information model.

Standard MBeans
A standard MBean is the simplest and fastest way to instrument a resource from scratch: attributes and operations are simply methods which follow certain design patterns. A standard MBean is composed of the MBean interface which lists the methods for all exposed attributes and operations, and of the class which implements this interface and provides the functionality of the resource.

Adding Management to your Application
This chapter explains how to enable your Java application for management. It shows how to use the Java Management Extensions API to enable management by iPortal Administrator. This chapter uses the iBank example to illustrate the steps involved. Adding management to your application involves two distinct stages. You must first decide on the features of your application that you wish the user to manage. You then add the management code to your application.

J2EE via JMX - Managing EJBs using JMX Agent
Enterprise JavaBeans is a state-of-the-art architecture for developing, deploying and managing reliable enterprise applications in production environment. However managing these EJBs or having client access using management protocols like SNMP,HTTP becomes very essential , especially for entity beans. AdventNet JMX architecture provides solution to manage entity EJBs using protocols like SNMP, HTTP, TL1, RMI, Corba.
|
|
AdventNet Agent Toolkit Java/JMX Edition 5.0
Most of the management systems are built from top to bottom either by SNMP, TL1 or HTTP. They leverage the specific facilities offered by the selected management protocol. For example, application server vendors are keen at SNMP for their management needs. Similarly TL1 is a man-machine management protocol deployed in broadband and access networks, including SONET networks. New technologies such as WDM and xDSL sometimes use the TL1 protocol for management of network equipment.

JMX (in French)
Les applications ont besoins d’être administrées à chaud. Il est intéressant de pouvoir intervenir sur le paramé-trage
de l’application, sans devoir l’interrompre. Par exemple, il doit être possible de modifier à chaud les critè-res
de traces afin d’identifier les problèmes.

JavaTM Management Extensions White Paper
Corporations and service providers are facing new challenges to manage service-driven environments in all industry segments. In these environments, the managed resources (which can indifferently be applications, devices, services or network policies) appear, move and disappear across the network, as they are created, installed, activated and used at a pace never experienced before.

Java Dynamic Management Kit
This White Paper describes some of the technology behind Java Dynamic
Management™ Kit: Sun Microsystems’ new paradigm for dynamic management.
Java Dynamic Management Kit is the foundation for building and distributing
dynamic network management intelligence into applications, networks, and devices.
Java Dynamic Management Kit technology provides a unique set of features that
radically changes the way companies solve their real-life management problems. By
leveraging existing standards like SNMP, and combining them with new
technologies based on Web and Java™ technology, it goes beyond the limitations of
current management systems to effectively address the new requirements of the
service age.

Container Services for High Confidence Software
Abstract. For high-confidence systems, substantial effort is expended to ensure that the
system will behave in an expected manner. This paper presents the position that a commercial
off the shelf Enterprise JavaBeans™ (EJB™) container can be extended to constrain the
behavior of high confidence software.

Java Dynamic Management Kit 4.0 Tutorial
The Java Dynamic ManagementTM Kit provides a set of JavaTM classes and tools for developing management solutions. This product conforms to the Java Management extensions (JMX), a specification which defines a three-level architecture: resource instrumentation, dynamic agents and remote management applications. The JMX architecture is applicable to network management, remote system maintenance, application provisioning and the new management needs of the service-based network.

Introducing A New Vendor-Neutral J2EE Management API
Through J2EE it became possible to create nearly vendor-neutral applications. These parts, which were still vendor-specific, were extracted in files, which could be adjusted during deployment of the application. For developers, this is great, but the development is only one part in the life cycle of the application. The management of the various J2EE application servers is especially difficult because every vendor has its own tool, which usually varies from version to version (see BEA WebLogic 5 and 6).

How to Integrate Custom Services via MBeans
The best way to add services to the JBoss server is to write your own JMX MBeans. An MBean is a Java object which implement resources and their instrumentation interfaces as defined in the Java Management Extensions(JMX) specification. Once written they are added to JBoss using the jboss.jcml which is used to configure the core JBoss MBeans. The best way for your EJBs to access your new services is to make them accessible via JNDI.
