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 the DB adapter to update a database table


In this recipe, we will configure an outbound DB adapter, so that it can be used to update data in one or more tables. The adapter will be invoked from a business service, which can be generated using Eclipse OE:

The business service implements a WSDL-based interface. The WSDL and XSD being used for that interface are generated by the DB adapter and are dependent on the database tables and their columns.

In this recipe, we will show how to wrap that business service with a proxy service using its own WSDL and XSD. By that we use a contract-first approach and have full control over the interface we offer to our consumers.

For the configuration of the DB adapter, we will use JDeveloper and then switch to Eclipse to implement the proxy service wrapping the inbound DB adapter.

Getting ready

For this recipe, we will use the database tables created with the OSB Cookbook standard environment. Make sure that the connection factory is set up in the database...
