Oracle Service Bus 11g Development Cookbook

Overview of this book

Oracle Service Bus 11g is a scalable SOA integration platform that delivers an efficient, standards-based infrastructure for high-volume, mission critical SOA environments. It is designed to connect, mediate, and manage interactions between heterogeneous services, legacy applications, packaged solutions and multiple Enterprise Service Bus (ESB) instances across an enterprise-wide service network. Oracle Service Bus is a core component in the Oracle SOA Suite as a backbone for SOA messaging. This practical cookbook shows you how to develop service and message-oriented (integration) solutions on the Oracle Service Bus 11g. Packed with over 80 task-based and immediately reusable recipes, this book starts by showing you how to create a basic OSB service and work efficiently and effectively with OSB. The book then dives into topics such as messaging with JMS transport, using EJB and JEJB transport, HTTP transport and Poller transports, communicating with the database, communicating with SOA Suite and Reliable Message Processing amongst others. The last two chapters discuss how to achieve message and transport-level security on the OSB.

Consuming a RESTful service from the OSB


In this recipe, we will show you how to consume an existing RESTful service from the OSB. We will reuse the service we have provided in the previous recipe and implement a proxy service/business service pair to expose it as a SOAP-based web service.

The business service is using the HTTP transport to invoke the RESTful service and a proxy service is exposing this as a SOAP-based web service, also using the HTTP transport.

In this recipe, we will only implement the RetrieveCustomerByCriteria operation.

Getting ready

Import the SoapUI project CustomerServiceCRM-soapui-project.xml from the location \chapter-5\getting-ready\exposing-restful-service\soapui into your SoapUI. Start the mock service CustomerServiceSOAP MockService.

Import the OSB project containing the implementation of the RESTful service into Eclipse OEPE from \chapter-5\solution\exposing-restful-service.

Import the base OSB project containing the right folder structure and the necessary XQuery...
