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.

Using Service Callout action to invoke a service


In this recipe, we will use a Service Callout action to call another service from a proxy service message flow.

We will use the sample setup from the first chapter of this book and add an additional service call to another service Credit Card Info Service, which returns the credit card information. The service call will be done using the Service Callout action. Both the information from the Credit Card Info Service and from the Customer Service will then be merged by the XQuery transformation into one single response returned by the proxy service.

Getting ready

You can import the OSB project containing the base setup for this recipe into Eclipse OEPE from \chapter-9\getting-ready\using-service-callout.

Start the soapUI mock services simulating the two external services on the CRM system by double-clicking on start-CreditCardInfoServiceCRM.cmd and start-CustomerServiceCRM.cmd in the \chapter-9\getting-ready\misc folder.
