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.

Invoking a SCA composite synchronously from an OSB service


In this recipe, we will create a SOA Suite composite application, which has a BPEL service component with a synchronous Direct Binding service interface. The direct binding interface will be invoked from an OSB business service through the SOA-DIRECT transport:

The SOA-DIRECT transport supports transactions and identity propagation across JVMs and uses the T3 RMI protocol to communicate with the SOA Suite server. It's important that the SOA Suite and the OSB server are on the same patch set level, otherwise we can get java class version errors.

Getting ready

Copy the soa-suite-invoking-soa-composite-sync holding the JDeveloper project from \chapter-8\getting-ready\invoking-soa-composite-sync\ into a local workspace folder.

Import the base OSB project containing the necessary schemas and the right folder structure into Eclipse from \chapter-8\getting-ready\invoking-soa-composite-sync.
