A. Fundamentals

  1. WebSphere Application Server: Product line

    Web site: WebSphere Application Server supports the broadest range of platforms in the industry so your applications can be built to run on the platform that makes most sense for your business. This site provides overview information on the WebSphere Application Server V7 product editions that are available.

    http://www-01.ibm.com/software/webservers/appserv/wasproductline/

  2. WebSphere Application Server V7.0: Technical Overview

    Redpaper: WebSphere Application Server is the implementation by IBM of the Java Platform, Enterprise Edition (Java EE) platform. It conforms to the Java EE 5 specification and is available in unique packages that are designed to meet a wide range of customer requirements. At the heart of each package is a WebSphere Application Server that provides the runtime environment for enterprise applications. This discussion centers on the runtime server component of WebSphere Application Server.

  3. WebSphere Application Server detailed system requirements

    Web site: Detailed hardware and software requirements for all supported releases of WebSphere Application Server. If you are unable to find a reference to a specific version of hardware ot software, remember that this document describes the minimum product levels that need to be installed before opening a problem report with the WebSphere Application Server Support team. Because other products frequently ship fixes, updates, and new releases, testing every configuration is not possible. In general, you can install and run with updates to supported products if those updates are forward compatible. For additional information about available support for configurations that are not included in the list, refer to support article WebSphere Application Server has grown and so have your requirements.

    http://www-01.ibm.com/support/docview.wss?rs=180&uid=swg27006921

  4. WebSphere Application Server Feature Packs

    Web site: IBM makes additional product features and functions available -- along with some of the latest standards -- through feature packs. With feature packs, you can selectively leverage new standards and features while maintaining a more stable internal release cycle. This page lists all available WebSphere Application Server feature packs. Be aware that some feature packs are generally available, while others might be beta versions.

    http://www-01.ibm.com/software/webservers/appserv/was/featurepacks/


B. Architecture

  1. WebSphere Application Server V7: Concepts, Planning and Design

    Redbook: Discusses the concepts, planning, and design of WebSphere Application Server V7.0 environments, ranging from small to large, and complex implementations. Addresses the packaging and the features incorporated into WebSphere Application Server, covers the most common implementation topologies, and addresses planning for specific tasks and components that conform to the WebSphere Application Server environment. Includes planning for WebSphere Application Server V7.0 and WebSphere Application Server Network Deployment V7.0 on distributed platforms, and WebSphere Application Server for z/OS V7.0, and also covers considerations for migrating from previous releases.

  4. Problem Determination through Defensive Infrastructure Architecture: Part 1: Runtime deployments with queues and ESBs

    Article: The widely known "keep it simple strategy" (KISS) is a wise practice to follow when building out an infrastructure. Application deployments, packaging, and placement requires considerable thought and effort to execute well. However, sometimes what appears to be a simple implementation can hinder problem determination leaving a production runtime unstable or, worse, unavailable. What is simpler for one side of the IT development or operations staff makes troubleshooting and root cause analysis that much harder because it is difficult to separate out discrete events or the lack of valuable but missing data. This article looks at some real life examples where "more is actually less" when it comes to KISS.

    http://www.ibm.com/developerworks/webservices/library/ws-probdetermination/index.html

  5. What you want to know about HTTP session persistence

    Article: Looking for the right session persistence strategy? Here are answers to questions you might have that will help you find the best solution for your requirements.

    http://www.ibm.com/developerworks/websphere/techjournal/0809_col_burckart/0809_col_burckart.html

  6. Why do non-functional requirements matter?

    Article: Functionality is important, but if you don't consider non-functional requirements -- which address how your solution is going to operate in the real world -- then your clever solution could end up being useless in practice. This is a list of non-functional requirements that are critical to success.

    http://www.ibm.com/developerworks/websphere/techjournal/0601_col_bobrha/0601_col_bobrha.html

e. OSGi

  1. Innovations within reach: Are we ready for enterprise OSGi?

    Article: Over the past year, there have been many heated debates over the readiness or otherwise of OSGi for enterprise applications. OSGi is a proven and tested technology, so in that sense it's been "ready" for a long time. What has been missing are specifications and implementations of tools and frameworks that are required for Java EE programmers to properly utilise OSGi enterprise features. The recent release of the OSGi Service Platform Enterprise Specification (4.2) and the announcement of the IBM WebSphere Application Server V7 Feature Pack for OSGi Applications and Java Persistence API (JPA) 2.0 changes this. Here is an overview of this new feature pack and the reasoning behind its development.
