Bpel Error Handling

there are number of mechanisms to handle exceptions that may arise while invoking certain piece of code. In BPEL as well there is a meachanism for handling faults.These faults should be oracle bpel error handling handled and required actions should be taken in event of failure at any stage.There

are two categories of BPEL faults: Business Faults Runtime Faults Business faults are application-specific faults that are generated when there wsdl error handling is a problem with the information being processed (for example, when a social security number is not found in the database). A business fault occurs when an application executes a throw activity or when

Web Services Error Handling

an invoke activity receives a fault as a response. The fault name of a business fault is specified by the BPEL process service component.A business fault can be caught with a faultHandler using the faultName and a faultVariable.Runtime faults are the result of problems within the running of the BPEL process service component or web service (for example, data cannot be copied properly because the variable name xslt error handling is incorrect). These faults are not user-defined, and are thrown by the system. They are generated if the process tries to use a value incorrectly, a logic error occurs (such as an endless loop), a Simple Object Access Protocol (SOAP) fault occurs in a SOAP call, an exception is thrown by the server, and so on.Several runtime faults are automatically provided. These faults are included in the http://schemas.oracle.com/bpel/extension namespace. These faults are associated with the messageType RuntimeFaultMessage. The WSDL file shown below defines the messageType: If a faultVariable (of messageType RuntimeFaultMessage) is used when catching the fault, the fault code can be queried from the faultVariable, along with the fault summary and detail. bindingFaultA bindingFault is thrown inside an activity if the preparation of the invocation fails. For example, the WSDL of the process fails to load. A bindingFault is not retryable. This type of fault usually must be fixed by human intervention.remoteFaultA remoteFault is also thrown inside an activity. It is thrown because the invocation fails. For example, a SOAP fault is returned by the remote service.replayFaul
