Introducing WebLogic Platform

# Introduction to WebLogic Platform

BEA WebLogic Platform is a unified, simplified, and extensible platform for building, extending, integrating, deploying, and managing applications. WebLogic Platform includes a rich development and deployment framework for integrating valuable resources and tools into your environment: third-party application packages, custom applications, messaging systems, Web services, trading partners, and more.

Based on a foundation of open standards that are leveraged throughout, WebLogic Platform ensures interoperability, flexibility, and choice, enabling integration with and between existing applications and resources, and extensibility through ISV applications and solutions.

This document is intended for software developers and managers who are new to WebLogic Platform and who want to understand its features and benefits.

# Components of WebLogic Platform

The WebLogic Platform product comprises multiple component products that can be used independently, or in combination, as required for your application. These component products, shown in the following diagram, are referred to as components for the remainder of this document.

The highlights of each component are described in the following sections.

## WebLogic Server—Foundation for the Platform

WebLogic Server delivers an easy-to-use, industrial application infrastructure for building and integrating distributed applications. WebLogic Server centralizes application services, such as Web server functionality, business components, and access to back-end enterprise systems. It is based on standards such as J2EE, Web services, and XML, and it provides standards-based integration to enable application integration and investment protection. WebLogic Server also provides enterprise-level security and powerful administration facilities.

WebLogic Server provides the foundation for WebLogic Platform. The WebLogic Workshop, WebLogic Portal, and WebLogic Integration components, and all applications built with these components, utilize the WebLogic Server run-time environment to meet the demands of applications that span one or more enterprises. Enterprise-class run-time capabilities provided by WebLogic Server include the following.

Scalability | Scale up to meet demand seamlessly and dynamically.
Security | Provide a single, unified security framework for all deployments—including portal applications, integration applications, and custom J2EE applications—that integrates best-of-breed security tools into a flexible, unified system.

## WebLogic Workshop—Development and Run-Time Framework

WebLogic Workshop is a unified, integrated development framework that makes it easy for all developers—not only J2EE experts—to build powerful, standards-based J2EE applications across the entire WebLogic Platform. The WebLogic Workshop architecture includes the following basic components:

- Workshop Integrated Development Environment (IDE)

A graphical environment that you can use for building, testing, and debugging WebLogic Platform applications. The Workshop IDE's intuitive user interface lets you design your application visually and hides the complexity of J2EE programming.

- Workshop Run-Time Framework

A program that compiles the annotated code created in the IDE and automatically implements the appropriate J2EE components, such as EJBs, JSPs, and JDBC connections, that are required to build and run the specified application.

The WebLogic Workshop IDE supports the ability to build applications that include any combination of the following:

- Enterprise-class Web services
- Web applications
- Java controls
- Enterprise Java Beans
- Portals
- Business processes

## WebLogic Portal—Window into Data and Applications

WebLogic Portal simplifies the production and management of custom-fit portals. WebLogic Portal simplifies, personalizes, and lowers the cost of access to information, applications, and business processes, whether the person who needs such access is an employee, a partner, or a customer. WebLogic Portal achieves this goal by leveraging a unified portal framework, simplified portal lifecycle management, and modular portal business services.

To speed the development and administration of portal applications, WebLogic Portal provides the following features.

With this feature . . . | WebLogic Portal provides . . .

# Benefits of WebLogic Platform

WebLogic Platform provides a single, highly integrated, high-performance, reliable solution, combining the advantages of a common application infrastructure with an easy-to-use, robust application development and management framework for the following classes of applications:

- Portal initiatives
- Enterprise integration
- Custom development

The following sections describe the commonly used application infrastructure and development paradigm supported by WebLogic Platform.

## Common Application Infrastructure

WebLogic Platform's common application infrastructure includes the following:

- Common framework for easy installation on target systems that supports the selection of Platform components to install; control of software usage through a single licensing mechanism; and support for commonly used hardware, operating system, and database combinations
- Common configuration of Platform components that supports the easy setup for application development, migration of applications to production environments, and the flexibility to accommodate the addition of Platform components to existing applications in response to new business requirements
- A common development paradigm. The Workshop visual programming model is based on the notion of controls—simple components that have methods, events, and properties with a visual representation in the design view—and annotated Java code, which lets you declaratively specify behavior and focus on handling events and calling methods, instead of writing complex object-oriented infrastructure code
- A highly reliable, available, scalable, extensible, standards-based, and high-performing foundation—WebLogic Server—that allows you to incorporate flexibility, extensibility, and choice into your IT solutions
- A unified and simplified management architecture, populated by distributed, heterogeneous technologies and platforms, that enables developers and administrators to realize business objectives

## Common Development Paradigm

WebLogic Workshop's unified architecture makes it possible for developers to learn only a single programming model for building and integrating the full suite of WebLogic Platform applications, including Web services, Web applications, portals, and business processes. Its development environment provides an intuitive user interface that lets you design your applications visually. It also abstracts the more complex J2EE programming. Applications you build in the IDE are constructed from high-level components rather than low-level API calls.

The most common way in which developers become familiar with WebLogic Platform is by experimenting with application development or by prototyping initial applications. The Workshop IDE is shown in Figure 1.

Figure 1 WebLogic Workshop IDE

The Workshop IDE simplifies application construction by providing a set of graphical elements, including the following:

1. The Application window is an area in which you can create, view, and edit files for your application. This window presents a hierarchical view of application files, making it easy to add or select files to work on.
2. A visual document workspace that presents two-way editing of your application: the Design View mode and the Source View mode. The Design View is a handy graphical tool for making coarse-grained modifications to your application, such as the addition of controls and method declarations. The Source View is useful for entering code, such as when you want to flesh out method logic. In the preceding figure, a Web service is being editing in the Design View. When you select an entity in the document workspace, the properties of that entity are displayed in the Property Editor.
3. The Palette contains often-used items that you may want to add to the entity in the document workspace. To create a new instance of a particular type of item, simply drag an existing instance of the desired item from the Palette to the document workspace.
4. The Data Palette displays a structural-list view of either the methods or attributes of controls and tags. For example, in the preceding figure, the Data Palette lists the methods of the `OrderRequisitionControl` process control. As you drag items from the Data Palette to the document workspace, code is inserted in the current entity to access the item being dragged.
5. The Property Editor enables you to view and set properties for the entity that is currently selected in the document workspace. For example, if you are creating a portal, you can customize the look and feel of that portal by setting its properties in the Property Editor.
6. The Document Structure window allows you to display a structured view of the components for the file that is currently selected in the document workspace.

The IDE also includes the following:

- Java controls—Components that have a predefined set of methods, events, and properties that encapsulate business logic. For example, you may have a control that can perform a database query, receive a JMS message, or execute business logic and return a result to the Workshop application. Java controls provide a powerful means of abstracting code so that a developer can focus on handling events and calling methods, instead of writing complex object-oriented J2EE infrastructure code.
- Java annotations—Code that conveys the appropriate run-time application behavior specified by the components you add, such as controls and property attributes. As you construct applications, the IDE adds these Java annotations, along with the required standard Java files. The Workshop run-time framework interprets these annotations and automatically implements the appropriate J2EE components, such as EJBs, JSPs, and JDBC connections, required to build the specified application.
- Debugging tool—Workshop supports an advanced cross-component debugging system. For example, this allows you to step from JSP code, to page flow code, and to code inside custom controls that you have written. Moreover, the debugging framework is leveraged by the other Platform products, so you can even debug from a business process into custom control code or JSPs. The JSP debugger lets you step through the execution of an individual JSP page and view the output stream as it is being constructed. Debugging performance has also increased significantly, and immediate mode and multithreaded debugging support have been added.
- Source editing features—Workshop's source code editor supports many popular productivity features. For example:

- When you use a class that has not yet been imported into your code, Workshop automatically prompts you to import that library.
- Holding down the Ctrl key and hovering over functions and variables provides additional information and links, respectively, to their definitions or declarations.
- Basic source editing features like auto completion have also been enhanced and expanded beyond Java functions and variables. For example, an `href` tag in a JSP or HTML page "autocompletes" to any file or image in the project.

- Online help—Tool that provides comprehensive reference information and hands-on instructions, as well as a rich set of tutorials that show how to build each type of application supported in Workshop.

### Applications You Can Create in Workshop

While you are developing applications in Workshop, the IDE provides easy-to-use access to views into those applications, in both the graphical Design View mode and the programmatic Source View mode. It also offers editors and palettes appropriate for each type of application, including the following:

- Web applications

To help you build dynamic, sophisticated Web applications, WebLogic Workshop provides Java page flows. A page flow is a Java class that controls the behavior of Web application components through the use of Javadoc annotations, methods, and, in most cases, forms. Java page flows provide an abstraction layer that helps you maintain efficiency in the following aspects of your Web application:

- Connections between pages
- Business logic actions that can be executed by pages
- Bindings between pages and back-end data sources

- Enterprise-Class Web Services

WebLogic Workshop makes it very easy to create and deploy Web services that adhere to Web services standards, such as Simple Object Access Protocol (SOAP) and Web Services Description Language (WSDL). Web services are accessed via XML messages. WebLogic Workshop provides tools for accessing and processing XML files received by Web services and for formatting XML responses. Web services built with WebLogic Workshop automatically leverage the power, reliability, security, and scalability of WebLogic Server, making them truly enterprise-class.

- Java controls

The Java controls model is extensible so that all users, including independent software vendors, can build tightly-coupled business logic components that seamlessly plug in to the Workshop's Integrated Development Environment (IDE). A key feature of a Java control is its ability to contain other controls. By nesting, you can use controls to wrap potentially complex business logic, along with access to resources, while exposing a relatively simple interface to developers. Once a control is created, it can be leveraged across all applications developed with Workshop.

- Enterprise Java Beans

Enterprise Java Beans (EJBs) are server-side Java components of enterprise applications. The J2EE Specification defines the types and capabilities of EJBs, as well as the environments, or containers, in which EJBs are deployed and executed. WebLogic Workshop provides a built-in control, called the EJB control, that makes it easy to use an existing, deployed EJB in your application. WebLogic Workshop also enables you to create new EJBs.

- Portal applications

WebLogic Portal provides a Workshop extension that includes designers for building portals, portlets, portal foundation services, personalization and interaction management, and integration services. These designers are graphical tools that enable you to create a sophisticated portal in minutes, by using a drag-and-drop function to manipulate data and setting properties on a grid. For example, if you create a portal file that appears with a default page and drag a sample JSP from the file tree onto that default page, a portlet is created for you automatically. You can then save the file and view the portal in a browser.

- Business processes

WebLogic Integration provides a Workshop extension for graphically implementing business processes that integrate applications, business users, trading partners, and other resources in the enterprise. Using the business process extension, the developer can define the process flow, the resources the process interacts with and the data that is passed to and from those resources, and the appropriate exception handling logic. The Mapper extension allows the developer to graphically map between XML, non-XML, and Java data within the business process. A set of integration controls is provided for use within the business process for integrating to a range of resources.

All these applications can be combined into a single application, all built in the same tool, and all sharing the same run-time characteristics provided by WebLogic Server.

Note that Workshop is a file-based system. All files created in Workshop are standard Java classes with annotations. While Workshop has many productivity features built into it, developers have the flexibility to use other IDEs for building applications that run on the Workshop run-time framework.

### WebLogic Server Programming Support

WebLogic Platform also provides and supports traditional WebLogic Server programming environments that allow developers to work within a level of complexity that is appropriate for them. For developers who prefer a flexible, low-overhead, custom development environment that includes off-the-shelf editors, such as Emacs or vi, WebLogic Server provides custom Ant tasks for the repetitive tasks required to build, configure, and deploy WebLogic Server applications. Any application built with these tools can be easily integrated into any other application that has been developed in the Workshop IDE.

# Solutions You Can Implement with WebLogic Platform

WebLogic Platform provides a comprehensive infrastructure for combining custom development, portal initiatives, and enterprise application integration in a single development and run-time environment. To demonstrate the kinds of solutions you can implement, the WebLogic Platform distribution includes a sample application, called the End-to End WebLogic Platform Tour. This sample application introduces you to the principal features of the WebLogic Platform product. It also provides a launching point from which you can get started with the development and integration of your own applications.

This section describes the End-to-End WebLogic Platform Tour: it summarizes the structure of the application and explains how key components of the application are developed with WebLogic Workshop. This section also emphasizes ways in which you can extend this application to encompass an even broader range of resources, giving you a robust and comprehensive implementation.

## About the End-to-End WebLogic Platform Tour

The WebLogic Platform Tour depicts a scenario in which Avitek, a major vendor of electronic office equipment, has developed a corporate intranet using WebLogic Platform. The corporate intranet enables employees and managers to view information from an employee information database and manage office equipment purchases. These capabilities are provided by two systems:

- The Employee Information system comprises a database with a "profile" of each employee. Employees can view the information in their profiles.
- The Office Equipment Order Management system integrates multiple business processes, such as Order Requisition, Order New, Billing, and Shipping, that are required in the life cycle of an equipment purchase. Each business process, in turn, invokes application modules that execute the back-end business logic and database transactions needed by the system.

The WebLogic Platform Tour shows how these functions can be integrated using WebLogic Platform.

The following sections explain how select components of the WebLogic Platform Tour are implemented with WebLogic Workshop:

- Developing the Intranet Portal Using WebLogic Portal
- Controlling the User Path Using Page Flows
- Using a Web Service to Invoke Business Processes
- Developing the Order Management System Using WebLogic Integration
- Using a WebLogic Workshop Enterprise Java Bean Control to Track Orders

This section concludes with links to a set of interactive demos from the documentation for the WebLogic Platform Tour. You can invoke these demos to see how to develop specific application components in Workshop.

## Developing the Intranet Portal Using WebLogic Portal

The underlying purpose of the intranet portal described in the WebLogic Platform Tour is to provide Avitek's employees with a single point of access to the company's applications and data. Specifically, the intranet portal must do the following:

1. Provide access to the Office Equipment Order Management System
2. Give employees access to their profiles in the employee database
3. Provide secure access to applications and data

You can use the WebLogic Workshop Portal Extensions to quickly create a portal that has these features and more. WebLogic Portal provides the ability to integrate existing Web applications, whether developed with WebLogic Workshop or with other tools and application environments, into a single portal that provides a unified view of applications. Web applications integrated into the WebLogic Portal environment, in turn, provide user access to back-end application functionality, databases, and other IT resources.

## Controlling the User Path Using Page Flows

The application accessed by this intranet portal consists of multiple Web pages. These Web pages need to be linked together into a unified set, so that an employee's path is well coordinated, and so that a variety of usage scenarios, including error conditions, can be handled appropriately. This linkage can be performed by a WebLogic Workshop feature called page flows, as shown in the following figure.

A page flow links together multiple Web pages in an application and coordinates the user's path through those pages and the associated flow of data. A page flow consists of a Java class with annotations, methods, and forms that are specifically designed to control the behavior of application components. Page flows are based on the Apache Struts framework.

## Using a Web Service to Invoke Business Processes

A Web service makes software application resources available over networks using standard technologies. Because Web services are based on standard interfaces, including XML, HTTP, SOAP, and WSDL, they can communicate even if they are running on different operating systems and are written in different languages. For this reason, Web services provide an excellent approach for building distributed applications that must incorporate diverse systems over a network, such as the intranet portal and Office Equipment Order Management System in the WebLogic Platform Tour.

WebLogic Workshop provides the tools and infrastructure you need to build and deploy enterprise-class Web services based on these standard technologies. WebLogic Workshop's environment for building Web services is both simple enough for the application developer and powerful enough for the J2EE expert.

The WebLogic Platform Tour uses a Web service to invoke the Order Requisition business process in the Office Equipment Order Management System, shown in the following figure. This Web service enables the application accessed by the intranet portal to be completely decoupled from the back-end business logic of the Office Equipment Order Management System.

## Developing the Order Management System Using WebLogic Integration

The Office Equipment Order Management System in the WebLogic Platform Tour is an application consisting of business processes that do the following:

- Control the lifecycle of an office equipment order
- Enable users to interact with business processes by using a WebLogic Integration feature called the Worklist
- Employ built-in Java controls, developed using WebLogic Workshop, that simplify access to business logic and enterprise resources

The Office Equipment Order Management System integrates these applications so that they can exchange documents and data efficiently. Some of the business logic and enterprise resources to be integrated can be extended to include the following:

- Custom software built by the company
- Prepackaged ERP applications provided by an independent software vendor
- Legacy systems that the company must continue using because it has made such big investments in them

The following figure shows how a business process fits into the Office Equipment Order Management System software to control the execution flow of various operations in that system.

WebLogic Integration provides the following capabilities to support the application integration and interoperability requirements of this Office Equipment Order Management System:

- Business process management provides an environment for quickly modeling, automating, and analyzing business processes that coordinate the interoperation of applications along with human interactions, to control the flow of business activity. For example, when a new equipment order arrives from a portal, a business process can send a message to the inventory application, to check for availability. Or, the business process can a send a message to a manager for approval, and branch the process based on the response received.
- Enterprise resource access makes it possible to integrate multiple order management applications. The WebLogic Platform Tour can be extended to include trading partner applications that coordinate online transactions with external suppliers. For example, equipment purchases might be coordinated by a RosettaNet business process, which could be integrated into the system.
- Dynamic integration services include:

- Adapters for delivering native connectivity to packaged enterprise applications. For example, the Office Equipment Order Management System might include an adapter for a prepackaged application that manages inventory.
- Message brokers provide highly reliable, asynchronous messaging, both inside and outside the company. For example, the message broker in the Office Equipment Order Management System can be configured to listen for incoming purchase order responses from trading partners.
- Data transformation for translating between XML and non-XML messages, which simplifies the exchange of documents by two or more of the applications in the Office Equipment Order Management System.

## Using a WebLogic Workshop Enterprise Java Bean Control to Track Orders

EJB controls make it easy for you to use an existing, deployed EJB from within an application. Normally, to obtain access to an Enterprise Java Bean (EJB), you must perform several preparatory operations: look up the EJB in the JNDI registry, obtain its home interface, and then obtain an instance of that EJB.

WebLogic Workshop uses the notion of an EJB control to simplify access to an EJB. Once you have created an EJB control, any application you create in WebLogic Workshop—a Web service, a business process, a page flow—can use the control to access the EJB's business methods directly. The EJB control manages communication with the EJB for you, including all JNDI lookup, interface discovery, and EJB instance creation and management.

The WebLogic Platform Tour provides an EJB to track the status of office equipment orders. The business processes in the Office Equipment Order Management System use an EJB control to simplify the task of accessing this EJB when updating or displaying the status of an order.
