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.

Working with global transactions and quality of service


This recipe will show the different error scenarios, which we can have with XA and non XA enabled resources and how QoS can influence this.

Getting ready

For this recipe, we will use a setup with three queues from the standard environment, a proxy service that consumes messages from a JMS queue, and a business service that sends th messages to another JMS queue:

You can import the OSB project into Eclipse from \chapter-10\getting-ready\working-with-global-transactions-and-qos.

How to do it...

First, we will show you the behaviour of the service without a global transaction.

In Eclipse OEPE, perform the following steps:

  1. Navigate to the proxy service JMSConsumer.

  2. Navigate to the Transport tab.

  3. Change the Endpoint URI to use the non-XA JMS Connection Factory : jms://[OSBServer]:[Port]/weblogic.jms.ConnectionFactory/jms.SourceQueue

  4. Navigate to the Message Flow tab.

  5. The message flow contains a Pipeline Pair node and a Route node with a Routing action...
