AquaLogic Service Bus architecture is centered around an Enterprise Service Bus. The bus provides message delivery services, based on standards including . BEA Systems, Inc. was a company specialized in enterprise infrastructure software products . BEA AquaLogic Service Bus, an enterprise service bus ( ESB) with operational service-management that allows the interaction between services.

In addition to exporting and importing resources, it is also permitted to export and import entire projects.
AquaLogic Service Bus provides a service callout swrvice that offers greater flexibility for more sophisticated message flows for complex dynamic-routing processing, or to perform message enrichment. AquaLogic Service Bus provides the ability to deploy new versions of services and allows you to have multiple versions of message resources such as WSDLs and schemas. The WebLogic security framework divides the work of securing a domain into several components providerssuch as authentication, authorization, credential mapping, and auditing.

Allows for better synchronization and notification capabilities. It is not meant to replace a more careful tuning of configuration that may be required by complex deployment scenarios. An EJB can be exposed as a Web service, without the need for tools or the modification of the legacy code on the application server that hosts the EJB. Global Operational Settings and operational values for proxy and business services. On a cluster of servers. They are definitions of the enterprise services with which you want to exchange messages.
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.
They are the interface that service consumers use to connect with managed back-end services. The Serice 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. The processing of messages occurs in the following sequence of events:. Operators have privileges to edit operational settings, create new SLA alert rules, and create and edit alert destination resources.
You can explore the other directories as an exercise.
Route messages according to XQuery-based policies or callouts to external Web services. The build script is used to build each of the services.
Concepts and Architecture
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. AquaLogic Service Bus built-in test console is a browser-based test environment used to validate resources and inline XQuery expressions used in the message flow. The Zervice Service Bus security model includes the following:.
XQuery-based policies or callouts to external services for message routing Routing policies that apply to both point-to-point and one-to-many routing scenarios publish.
Henley Mark Hurd Jack F. This way, ongoing changes can be made without disrupting services.
Communication between different departments is achieved through a federated network of ESBs, which talk to each other, often through firewalls. There are no restrictions on what can be exported. These tutorials use the AquaLogic Aquaalogic Bus example suite as a basis for instruction.
You must start the server before building the Web services. A set of transformations that affects context variables can be defined before the message is sent to the selected endpoint or after the response is received.
Getting Started with the BEA AquaLogic Service Bus Tutorials
Using generic proxy templates, the proxy service can be a configured as a message-flow definition that dynamically routes messages to appropriate business services based on content-based routing logic. Define a transformation on an XML message, based on XQuery, supporting xqualogic call out to a Web service to gather additional data for the transformation.
Aqalogic request message starts at the start node and follows a path to a leaf node, executing actions in the request pipelines. A high performance message broker is a core component of AquaLogic Service Bus. Save the changes and close setDomainEnv.
To test the deployed Web service, Enter ant run then press Enter.
