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.

Although he has extensive knowledge and experience with other Oracle Fusion Middleware products, the Service Bus has become his specialty.

Now, he is working as an independent consultant on a variety of projects, ranging from enterprise architecture to working with Oracle Fusion Middleware products. In his role as an independent consultant, he is still asked by Oracle to help them out on occasions.

Matthias Furrer has been working in different roles for more than 20 years in IT. Throughout his career he worked as an application developer, consultant, and architect in many complex integration projects. Now, he is working as a senior consultant for Trivadis—a leading solution provider for infrastructure engineering, application development, and business intelligence operating in Switzerland, Germany, and Austria.

Peter van Nes is an Oracle Fusion Middleware consultant and works within a partnership of the Oracle SOA Specialized Gold Partner, The Future Group. In 1991, he started his career as a Systems Management consultant and changed his focus in 2005 to Oracle products and Java. In his current assignment, he mainly develops BPEL processes and OWSM security pipelines for an international financial services provider, and, as a senior developer, he is actively involved in the migration to 11g SOA Suite, using BPEL and OSB. In addition, Peter contributes to the Oracle community by blogging on his website, http://www.petervannes.nl.
