IBM WebSphere Application Server V8 Concepts, Planning, and Design Guide

It delivers a proven, secure, robust, and reliable software portfolio that provides an excellent return on investment. Java is the technology that powers WebSphere products. Over the years, many software vendors have collaborated on a set of server-side application programming technologies that help build web accessible, distributed, platform-neutral applications. Java SE supported the development of client-side applications with rich graphical user interfaces GUIs.

The Java EE platform, which is built on top of the Java SE platform, provides specifications for developing multitier enterprise applications with Java. It consists of application technologies for defining business logic and accessing enterprise resources such as databases, enterprise resource planning ERP systems, messaging systems, internal and external business services, and email servers.

Java EE 6, the latest release of the Java EE platform, represents a significant evolution in the Java enterprise programming model. Now, J2EE 1. This book provides information about these standards with their new names. Chapter 1.

Web services allow for the definition of functions or services within an enterprise that can be accessed by using industry standard protocols such as HTTP and XML that are already in use today. These protocols allow for easy integration of both intrabusiness and interbusiness applications that can lead to increased productivity, expense reduction, and quicker time to market. Web services are also the key elements of SOA, which provides reuse of existing service components and more flexibility to enable businesses to address changing opportunities. This section gives an overview of the options and functionalities that WebSphere Application Server V8.

It insulates the infrastructure from hardware, operating system, and the network Figure An application server serves as a platform to develop and deploy your web services and EJBs. It also serves as a transaction and messaging engine. An application server also delivers business logic to users on various client devices. It provides a programming model, an infrastructure framework, and a set of standards for a consistent designed link between them. WebSphere Application Server provides the environment to run your solutions and to integrate them with every platform and system, as business application services conforming to the SOA reference architecture Figure WebSphere Application Server is available on a range of platforms and in multiple packages to meet specific business needs.

By providing the application server that is required to run specific applications, it also serves as the base for other WebSphere products and many other IBM software products. As business needs evolve, new technology standards become available. The reverse is also true. Since , WebSphere has grown and adapted itself to new technologies and to new standards to provide an innovative and cutting-edge environment so that you can design fully integrated solutions and run your business applications.

With these packages, you can create basic scenarios with single application server environments. Furthermore, you can extend your environment to include multiple application servers that are administered from a single point of control, the deployment manager. These application servers can be clustered to provide scalable and high available environments.

You can include stand-alone and Network Deployment servers in such topologies.

It installs the desired level of service in one pass. It provides greater flexibility and ease for administrators to manage logging resources and work with log and trace content. You can use it to group and manage Java EE and other related artifacts under a single application definition. Through monitored directory-based application installation, update, and uninstallation of Java EE applications. It also includes enhanced AdminTask commands.

Runtime provisioning With the runtime provisioning mechanism in WebSphere Application Server, the application server run time can select only the necessary functions for memory and space dynamically while running applications. Starting only the necessary components for an application reduces the server footprint and startup time. Each security domain can have its own user population and underlying repository. Additionally, the application domain can be separated from the administrative domain.

These actions can be security configuration changes, key and certificate management, access control policy changes, bus and other system resources management, and so on. With this feature, you can hold administrative users accountable for configuration and runtime changes. You can restrict access based on the role of the administrator at the cell, node, cluster, or application level, offering fine-grained control over administrator scope.

This capability is valuable in large-cell implementations where multiple administrators are responsible for subsets of the application portfolio running on the cell. Rather than define individual policies and apply them on a web service base, policy sets can. Thumbnails Document Outline Attachments. Highlight all Match case. Toggle Sidebar. Zoom Out.

When a message arrives at the destination, the MDB is invoked and its onMessage method called. If a "poison message" is delivered to an MDB, the application can choose to reject it. In this situation, what happens to the message and how does the application server behave?

A poison message is simply a message that the receiving MDB application is unable to process. It could be that the message has become corrupt, is in an unexpected format, or contains information that cannot be handled by the MDB's business logic. For example, suppose you have an MDB that processes book orders. If a poison message is delivered to an MDB, the bean can do one of three things: roll back the message to the destination that it came from This is useful if the application was unable to handle the message due to a temporary problem, such as a database being unavailable.

To roll back the message, the MDB should call the setRollbackOnly method on the message-driven context associated with the bean.
