Oracle Service Bus provides a service callout action that offers greater FLEXIBILITY for more sophisticated message flows. Service Callouts are message processing request actions from one message flow, that invoke other services registered within Oracle Service Bus. This action is generally used in response to decisions made in COMPLEX dynamic-ROUTING processing, or to perform message enrichment.

The service callout action is used inside a message flow routing stage, to call on the destination service to perform some action on the message. The destination service RETURNS a response to the message flow, which gets assigned to a local variable. The variable may be used within the current message flow for conditional branching.

Service callouts allow custom Java code to be invoked from within proxy services. Oracle Service Bus supports a Java EXIT mechanism via a Java Callout action that allows call out to a Plain Old Java Object (POJO). Static methods can be accessed from any POJO. The POJO and its parameters are visible in the Oracle Service Bus Administration Console at design time; the parameters can be mapped to message context variables.
