enables you to configure your system to format and return error messages. Errors can occur during Message Flow processing for various reasons. For example, security errors occur if a username is not correctly validated or authorized; transformation errors occur if AquaLogic Service Bus is unable to successfully transform or validate a message; a routing error is raised if a routing oracle service bus error handling service is unavailable, and so on. Typically, these errors originate from a specific stage, route node or from the proxy service, as this is where most of the Message Flow logic is implemented. AquaLogic Service Bus provides a mechanism to handle these errors by enabling you to define error handlers. An error handler is a pipeline that allows you to perform various actions such as logging, transformation, and publishing to handle errors appropriately. If an error occurs within a stage a sequence of steps are executed. This sequence of steps constitutes an error pipeline for that stage. Nested Error Handlers You can configure an error handler for the entire Message Flow as well as for every pipeline and stage within the Message Flow. You may also configure error handlers for route nodes but not for branch nodes. When an error occurs, it is handled by the inner-most encompassing error handler. For example, a stage's error handler handles a transformation error if it occurs while executing the assign action in that stage. If there is no error handler configure

response, by populating the fields like “ErrorNumber” and “ErrorMesssage”. Assuming that these

fields are defined in the response message structure in WSDL. As a SOAP fault Typically when OSB is osb error handling tutorial mediating between service consumer and service provider, we might have to transform this error response or fault response to the response structure defined in the proxy WSDL. So we need https://docs.oracle.com/cd/E13171_01/alsb/docs21/consolehelp/proxyerrors.html to understand on what message context variables can be used for this transformation. As per WS-I BP, the service provider should send the HTTP response code as 200 when the error is being sent back as normal response and 500 should be sent when the error being sent back in form of the SOAP fault. When HTTP response code 200 is https://svgonugu.com/2011/06/15/fault-handling-in-osb/ received, OSB treats it as a normal response and $body will have the received response. And when response code 500 is received, the OSB runtime control goes to the ‘Service Error Handler’ if present or to ‘System Error Handler’. That means OSB considers the fault response also as a normal response and populates $body, when response code is 200 is received for fault response. And OSB populates different message context variables in case of fault response with 500 code depending on whether Routing or Service Callout are used to call the business service. When routing is used, the variable $body will have the fault response. When service callout is used, the variable $fault will have the fault response in ‘ReceivedFaultDetail’ structure. For demonstrating the same, the following SOAP fault structure is used as a response in SOAP UI mock service.
