Fault names are not required to be defined prior to their use. An application or process-specific fault name can be directly used by employing an appropriate QName as the value of the faultName attribute and providing a variable with the fault data if required. This provides a very lightweight mechanism to introduce application-specific faults. A simple example that does not provide a variable for the fault data is shown in Listing 16-9.

The simple primitive activities we just discussed are usually combined into more complex algorithms that specify the business process. For this purpose, BPEL supports many structuring activities. We now discuss some of the important structuring activities.

activities that will be performed in an ordered sequence, which is determined by the order in which the activities are listed. This is depicted in a schematic manner in Figure 16.5. The sequence activity completes when the final activity in the sequence has completed. An example of the sequence activity is shown in Listing 16-10.

The ow Activity This activity is used to group a set of activities that
will be performed in parallel, as shown schematically in Figure 16.6. The most fundamental semantic effect of grouping a set of activities in a flow is to enable concurrency. A flow completes when all the activities in the flow have completed. Sample code for a flow activity is shown in Listing 16-11.

The switch Activity This activity is used for implementing branches, as shown schematically in Figure 16.7. This structuring activity has the same effect and construction as the switch statement in many programming languages such as Java and C/C++. This activity consists of an ordered list of one or more conditional branches defined by case elements, followed optionally by an otherwise branch. The case branches of the switch are considered in the order in which they appear. The first branch whose

condition holds true is taken and provides the activity performed for the switch. If no branch with a condition is taken, then the otherwise branch is taken. A sample illustration of the use of the switch activity is shown in Listing 16-12.
Listing 16-12
Listing 16.12: Illustration of switch activity 1 <switch> 2 <case condition="boolean expression 1"> 3 4 </case> 5 <case condition="boolean expression 2"> 6 . 7 </case> 8 <otherwise> 9 10 </otherwise> 11 </switch>
The while Activity This activity defines a loop and also has the same effect as in other programming languages such as Java and C/C++. This activity supports repeated performance of a specified iterative activity. The iterative activity is performed until the given Boolean while condition no longer is true. The syntax of the while activity is shown in Listing 16-13. Listing 16-13

Integration Through Service Composition (BPEL)
The pick Activity The pick activity awaits the occurrence of one of a set
of events and then performs the activity associated with the event that occurred. The occurrence of the events is usually mutually exclusive in that the process will either receive an acceptance message or a rejection message, but not both. The form of pick is a set of branches of the form event/activity, and exactly one of the branches will be selected based on the occurrence of the event associated with it before any others. Note that after the pick activity has accepted an event for handling, the other events are no longer accepted by that pick. The possible events are the arrival of some message in the form of the invocation of an inbound one-way or request/response operation, or an alarm based on a timer (in the sense of an alarm clock). This particular scenario is illustrated in Listing 16-14.
Listing 16-14
Listing 16.14: Sample code for the use of pick activity 1 <pick> 2 <onMessage > 3 activity 1 4 </onMessage> 5 <onAlarm> 6 activity 2 7 </onAlarm> 8 </pick>
Practical Example We now demonstrate how the preceding constructs of BPEL come together with an example of a business process (see Listing 16-15). Note that this example is for illustration purposes only and is not meant for actual production use. This example is missing some important details, including any fault handling. In this example, we consider a business process for obtaining the best ticket offer from two airlines (United Airlines and US Airways) for a business traveler. The business process is shown in Figure 16.8, whereas the interactions of this business process with the customer and three other Web Services are depicted in Figure 16.9. In the process shown, the business process customer (that is, the business traveler) obtains the best ticket offer from the business process through a synchronous call. For this purpose, the business process provides a portType to the customer, as shown on the left of the business process in Figure 16.9. After receiving a request from the customer, the business process makes an asynchronous call to the human resource Web Service to check the status of the customer as a business traveler. Then the process
