About This Book


During the Internet revolution, the organizational motto was to quickly deliver content (information) and functionality (Web-enabled applications) to end users via the Web. Organizations were extremely successful in leveraging Web technologies to deliver eye- candy and static content, but retrospectively, the delivery of enterprise-class Web applications was not a measurable success.

The term success always needs to be calibrated against some criteria for it to be measured. For organizations implementing Web-enabled applications, the initial success criteria were to meet the business requirements and deploy the applications within the context of a project budget and timeframe ”a simple time-to-market formula. What organizations overlooked was how to derive organizational agility from their application infrastructure (software platform) investments, thus enabling the following:

  • Application architectures to naturally mold and adapt to evolving business requirements

  • Interoperability between existing systems without costly and time-consuming infrastructure overhauls

  • Emerging technology standards to be embraced

As a general rule, organizations must expect change, accept change, and embrace change to succeed. This same rule applies to the application infrastructure an organization relies on as a platform to power its enterprise Web applications. For this reason, today s success criteria for enterprise-class Web applications go beyond just obeying the time-to-market formula; the application infrastructure must also be future-proofed to accommodate business-driven and technological changes.

To derive a unified , simplified , and extensible application infrastructure platform that organizations could leverage to be more technically agile, BEA introduced the WebLogic Platform 7 ”a complete and modular Java 2 Platform, Enterprise Edition (J2EE) application infrastructure solution that minimizes the number of middleware products required to develop, deploy, maintain, and integrate a diverse array of Web-enabled business solutions. The WebLogic Platform is also the first application infrastructure offering that is represented through a single product: one documentation, installation, configuration, deployment, management, and security framework. The value proposition here is that you can have complete confidence that the products composing the WebLogic Platform are all certified to be compatible and will work seamlessly together without any wiring of infrastructure services or use of interface adapters.

At the core of the WebLogic Platform is WebLogic Server, which is by far the most widely adopted and battle- tested J2EE application server for developing and deploying industrial-strength J2EE applications and enterprise-class Web services with unparalleled reliability , availability , scalability , performance , and security . If you are learning J2EE, have a desire to become a J2EE application server administrator, or just want to ensure that your current J2EE proficiency is marketable, knowledge of the WebLogic Server product is an incredible asset.

To support sophisticated and knowledge-based Web applications that consolidate content and functionality through a unified interface, BEA provides WebLogic Portal, a comprehensive portal framework and development environment.

To enable J2EE applications hosted on WebLogic Server to interoperate with systems within and beyond an enterprise, BEA provides WebLogic Integration, a standards-based solution for integrating complex e-business processes and applications, and for providing B2B and data transformation services.

The WebLogic Portal and Integration products are both infrastructure services and functional extensions of WebLogic Server, which implies they both leverage J2EE and non-J2EE services provided by WebLogic Server ”for example, a unified Java Messaging Service (JMS) bus and a flexible security infrastructure.

The WebLogic Workshop is BEA s new visual development framework and environment for creating enterprise-class Web services, which greatly simplifies Web service development and testing using J2EE. This framework enables business application developers to harness the power of J2EE without having to climb the ultra -steep learning curve of J2EE programming. WebLogic Server implements the WebLogic Workshop Runtime Framework, a Java Web Service (JWS) container, for running, testing, and debugging visually authored Web services. The Web services deployed in the JWS can be leveraged by J2EE applications as well as by portal applications and integration services developed through WebLogic Portal and WebLogic Integration.

This book has a simple, but important mission ”to align you through human and software (socio-technical) engineering principles with today s success criteria for developing, deploying, and managing enterprise-class J2EE Web applications and Web services by leveraging an agile application infrastructure: the WebLogic Platform.
