Using Fault Handling in a BPEL Process

12 Using Fault Handling in a BPEL Process

This chapter describes how to use fault handling in a BPEL process. Fault handling allows a BPEL process service component to handle error messages or other exceptions returned by outside web services, and to generate error messages in response to business or runtime faults. This chapter also describes how to use the fault management framework to catch faults and perform user-specified actions defined in a fault policy file.
