Using the For Each action to process a collection

This recipe will show we can loop over a collection of information by using the For Each action. We will implement a proxy service accepting a Customer element through a one-way interface. The proxy service will use the For Each action in its message flow to loop over the single addresses inside the addresses collection.

Each address will then be sent to an Address Checking Service which would check the address for correctness. In our case, this service is a mock service implemented in soapUI. To better see the sequential nature of the processing, the Address Checking Service is written so that it takes four seconds to respond.

Getting ready

You can import the OSB project containing the base setup for this recipe into Eclipse OEPE from \chapter-9\getting-ready\using-foreach-to-process-collection.

Start the soapUI mock service simulating the Address Checking Service by double-clicking on start-AddressCheckingService.cmd in the \chapter-9\getting...
