A branch node to branch based on the values in designated parts of the message or message context or to branch based on the operation invoked. There are two subdirectories: Route messages according to XQuery-based policies or callouts to external Web services.
This tutorial focuses on the configuration of the proxy service. An extended list of environment variables allows settings to be preserved or tailored when moving from one environment to another. The jws Web service definition. Four business service folders exist in this directory.
It is also possible to import only a subset of the exported data. Decoupling the routing, transformation, security, and transport details from the service consumers and providers and placing them within configurable proxy services, provides for more flexible service integration. While developing the tutorial you will modify some of the files contained in this folder, such as examples. This capability allows system configuration to be propagated from one instance of AquaLogic Service Bus to another instance by exporting all, or a subset of, the resources deployed in the source AquaLogic Service Bus domain.
Concepts and Architecture
The Configuration Wizard guides you through the process of creating a new domain using the configuration templates. Routing a Loan Application is based on scenarios that demonstrate how AquaLogic Service Bus facilitates the routing of messages within an enterprise.
The following conventions are used throughout this document: This API enables integration with management partners and enables customers who have their own monitoring consoles to display metrics that can be used for performance analysis.
This provides a centralized way for administrators to manage remote EJB server configurations. In addition to exporting and importing resources, it is also permitted to export and import entire projects. It is possible to preserve operational settings in the importing domain from being overwritten during import. A set of transformations that affects context variables can be defined before the message servive sent to the selected endpoint or after the response is received.
Getting Started with the BEA AquaLogic Service Bus Tutorials
From Wikipedia, the free encyclopedia. This tutorial highlights specific features available in AquaLogic Service Bus. It includes following products:. WS-Security processing as well as authorization is transparently performed at sdrvice Start node, when invoking a business service with a WS-policy.
Views Read Edit View history. These instances have their own sets of configuration artifacts such as services and transformations.
BEA Systems – AquaLogic Service Bus Documentation
The basic concepts underlying AquaLogic Service Bus are described in this section. For more information on proxy templates, see Service Composition in the Concepts and Architecture Guide. AquaLogic Service Bus is policy driven and enables you to establish loose coupling between service clients and business serviceswhile maintaining a centralized point of security control and monitoring. A server command console window, which shows status information about Weblogic Server is displayed. You do so in the WebLogic configuration section in the following file:.
Vulnerabilities with publish dates before are not included in this table and chart. Such deployments typically map to various IT departments within an organization. Change to the normal directory: 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.
Read-access to databases from proxy services is supported without requiring writing of a custom EJB or custom Java code and without the need for a separate database product like AquaLogic Data Services Platform.
The company’s name is an initialism of the first names of the company’s three founders: This allows a more efficient and flexible approach to accessing data services than exposing them as Web services via WebLogic Workshop and Java Web Services JWSand it supports security and identity propagation.
Since a proxy service can route messages to multiple business services, a proxy service can be configured with an interface that is independent of the business services it communicates with. Stores information about services, schemas, bs, WSDLs Web Service Definition Languageand WS Policies Provides centralized management and distributed access to resources and services Allows browsing of services registered in AquaLogic Service Bus and import hus resources from WebLogic Workshop or other applications Allows the propagation of configuration data from environment to environment for example, from a development domain to a test domain to a production domain.
In the examples directory, on the command line, run the following command: The context can be read and modified by XQuery expressions and updated by transformation and in-place update actions. You must complete the steps in this section before you start the tutorials. Aquqlogic is buz for moving messages from AquaLogic Service Bus to the business service or proxy service and for receiving the response from the services.
The AquaLogic Service Bus Console also allows export of a resource and all the other resources on which it depends, using the dependency tracking feature. The last nodes in a branch leaf nodes may be route nodes or echo nodes. 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 supports dynamic content-based routing of messages and run-time protocol selection. Predefined context variables contain information about the message, transport headers, security principles, metadata for the current proxy service, and metadata for the primary routing and publishing services invoked by the proxy service.
Authentication, encryption and decryption, and digital signatures as defined in the Web Services Security WS-Security specification Uses SSL to support traditional transport-level security for HTTP and JMS transport protocols One-way and two-way certificate based authentication HTTP basic authentication Encrypt and export of resources such as service accounts, proxy service providers, UDDI registries, SMTP providers, and JNDI providers that contain username and passwords Create service accounts and proxy service providers within a session, and add the user name, password, and credential alias binding within the same session.
It facilitates these capabilities by allowing the configuration of proxy services with interfaces that are independent of the end-point business services. If the leaf is an echo node, the request is also considered to be the response. The workaround uses the subst command to shorten the classpath passed by ant.
The build script is used to build each of the services.
The applicants credit rating information is required in one of the scenarios to complete the loan request. AquaLogic Service Bus supports the following error handling capabilities:. 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.
