It is targeted for service-oriented integration, managing Web Services, and providing traditional message brokering across heterogeneous IT environments. AquaLogic Service Bus manages the routing and transformation of messages in an enterprise system to promote seamless application integration.
The AquaLogic Service Bus Console enables you to configure a proxy service specific to your needs and to manage your Web services by controlling the service and policy configurations and by monitoring system and operations tasks. The following figure illustrates the intermediary function of Servkce Service Bus, and shows the servers on which it relies. AquaLogic Service Bus allows you to manage your Web services and deliver true message brokering through the configuration of proxy services in the AquaLogic Service Bus Console.
It is used to resolve differences in requirements between business services and service clients. The basic concepts underlying AquaLogic Service Bus are described in this section.
In this tutorial you will see the benefits of using AquaLogic Service Bus acting as an intermediary between clients and business services.
This tutorial focuses on the configuration of the proxy service. AquaLogic Service Bus is also used to manage your Web services. The configuration functions are separated from the management functions in the AquaLogic Service Bus Console.
This separation allows implementations to evolve independently and dynamically, as driven by the needs of the business without requiring costly infrastructure development efforts. AquaLogic Service Bus provides intelligent message brokering between business services such as enterprise services and databases and service clients such as presentation applications or other business services through proxy services that you configure using the AquaLogic Service Bus Console.
With AquaLogic Service Bus message brokering, service clients exchange messages with an intermediary proxy service rather than working directly with a business service. A proxy service can route messages to multiple business services; you can choose to configure a proxy service with an interface that is independent of the business services with which the proxy service communicates.
In such cases, you would configure a message flow definition to route a message to the appropriate business service and map the message data into the format required by the business service’s interface.
Business services are remote services or external endpoints that are typically not implemented by the AquaLogic Service Bus server. They are definitions of the enterprise services with which you want to exchange messages.
You configure the logic for the manipulation of messages in proxy service message-flow definitions. This logic includes such activities as transformation, publishing, and reporting, which are implemented as individual actions within the stages of a pipeline.
Pipelines are one-way processing paths that include no branching. Each pipeline is a sequence of stages. A stage is a user-configured processing step. Messages fed into the pipelines are accompanied by a set of message context variables that contain the message contents and can be accessed or modified by actions in servvice pipeline stages.
Pipeline pairs are request and response pipelines.
The request pipeline definition specifies the actions that AquaLogic Service Bus performs on request messages to the proxy service before invoking a business service or another proxy service. The response pipeline definition specifies the aualogic that AquaLogic Service Bus performs on responses from the service invoked by the proxy servife before the proxy service returns a response to a client.
These tutorials show how AquaLogic Service Bus is used to route a loan applications to appropriate business services based on the configurations set in the proxy service.
The AquaLogic Service Bus Console is comprised of JSP-based portlets that support the configuration and design of the proxy service message flows and the associated resources. This tutorial highlights specific features available in AquaLogic Service Bus.
BEA AquaLogic Service Bus™
In the tutorial you will use the console to create the proxy service that will interact with the service client and business services.
Working through the tutorial you will:. You will learn how to configure and use BEA AquaLogic Service Bus to resolve the business scenarios presented in the specified use cases.
Using the tutorials will:. Complete the first tutorial, Routing a loan application, to become familiar with BEA AquaLogic Service Bus, then proceed to the other tutorials provided as part of the tutorial suite:. The following conventions are used throughout this document:. Overview of the Tutorial These tutorials show how AquaLogic Service Bus is used to route a loan applications to appropriate business services based on the configurations set in the proxy service.
Working through the tutorial you will: Learn how to configure the proxy services to process the input and output messages in a message flow.
Create, read, and update configuration objects such as proxy services, WSDLs, and so on. See how AquaLogic Service Bus handles session management to allow configuration changes to happen locally, and then when complete, to instantiate the changes in the core environment. Route messages according to XQuery-based policies or callouts to external Web services. Define a transformation serice an XML message, based on XQuery, supporting a call out to a Web service to gather additional data for the transformation.
See how message processing by AquaLogic Bue Bus is driven by metadata specified as the message flow definition for a proxy service in the AquaLogic Service Bus Sevrice. Using the tutorials will: Provide the basic steps that will help you to learn to configure more complicated scenarios.
