Creating a custom logger in a BPEL process

In this recipe, we will define a custom logger for a BPEL process. We will define a custom logger as an addition to the already existing loggers available for BPEL processes. The custom loggers are used in a scenario where there is a special requirement that ODL cannot fulfill, for example, if some logging information needs to be sent over the TCP socket, or if we want to provide special formatting types for logging.

Finally, we check for the car reservation.
