BPEL Designer Tutorial Tutorial 2: Developing a Credit Flow BPEL Process In this tutorial you will learn how to use the Oracle BPEL Designer to build, deploy, and test your second BPEL process. The process is an asynchronous flow that calls a simple service: a synchronous credit rating service. Creating this process is intended to be the first step toward building a more sophisticated application (like BPEL Loan Flow example). This tutorial is based on version 0.8 of the BPEL Designer.

Prerequisites This tutorial assumes you have completed Tutorial 1, “Developing a Hello World BPEL Process.” The same prerequisites apply as for that tutorial (as listed below); you should have the BPEL Designer installed on your system as well. • Oracle BPEL Process Manager, version 2.0 RC8 or later installed on your system • Internet Explorer 6.0 • JDK 1.4.1 (or later) • Windows 2000 or XP, 384 MB RAM • 100 MB of disk space for the BPEL Designer (including the Eclipse 3.0M9 distribution) • Some familiarity with XML Schema, WSDL, XPath, BPEL, and related Web service standards Getting Started If the BPEL Designer and Oracle BPEL Process Manager are not currently running on your desktop, start them now, as described in Tutorial 1. Like that tutorial, this one assumes you have installed the Oracle BPEL Process Manager on a Windows system into the C:\orabpel directory, so you should modify paths as appropriate if you have installed it into a different location or operating system. Before starting the main content of this tutorial, you should compile and deploy the credit rating service that you will invoke as part of the tutorial, making it available on your local Oracle BPEL Process Manager. You will use the command line rather than the BPEL Designer to compile and deploy this service Note that i…
