Using BPEL to Build Composite Services and Business Processes - Oracle SOA Suite 11g R1 Developer's Guide - page 137

So let's create our stock quote service, we will create a simple synchronous BPEL
process which takes two parameters, the stock ticker and the required currency.
This will then call two external services.
Creating our StockQuote service
Before we begin, we will create an application (named Chapter05) , which we will
use for all our samples in this chapter. To do this, follow the same process we used to
create our first application in Chapter 2 , Writing your First Composite . When prompted
to create a project, create an Empty Composite named StockService .
Next, drag a BPEL process from the SOA Component Palette onto our StockService
composite. This will launch the Create BPEL Process wizard, specify a name of
StockQuote , and select a Synchronous BPEL Process . However, at this stage
do not click OK .
