Invoking web services in parallel
In cases where the invocation of web services is not interdependent, we can invoke web services in parallel. The parallel invocation shortens the BPEL process execution time. In this recipe, we will show you how to invoke web services in parallel.
Getting ready
For this recipe we will consume two web services. We will check for the hotel room and car availability in parallel. The availability data will give us information on hotels, where the rooms are available, and a car that is available for the date range.
