Handling This section includes the following topics: Error Handlers Nested Error Handlers Empty Error Handlers Error Handler Actions Error Handler Configuration Error Handlers osb error handling tutorial BEA AquaLogic Service Bus 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 osb error handling framework 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 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
Osb Service Callout Error Handling
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 configured for the stage, it is handled by the next level error handler, which is that of the pipeline that contains the transformation stage. If that error handler does not exist, it is then handled by the Message Flow-level error handler. If that fails, then a default system-level error handler processes the error. The next level error handler for uncaught errors that occur in a route node is the Message Flow-level handler. Thus, unlike stage errors which can be handled at 3 levels by user-configured handlers, Message Flow errors can only be caught by at most 2 levels of user-configured handlers. Every component--stage, pipeline or Message Flow--ca
in OSB. I have also included a sample project which makes it very easy to try different scenarios that can help broaden your understanding of OSB Error Handling. These examples are raise error in osb meant to give some guidance but please try different scenarios and if there is difference between reply with success and failure in osb something you are curious about add it to one of the proxy services and see what OSB does. Before we

start with the hands-on exercises below is a quick overview of the key points in OSB Error Handling. OSB Error Handling Overview Error handling can be configured at 4 different areas in and https://docs.oracle.com/cd/E13171_01/alsb/docs21/consolehelp/proxyerrors.html OSB Proxy Service. Proxy Service Route Node Pipeline Stage Node If an error is not handled in any of these areas then it will be caught in the System error handler. An error will be handled by the inner-most encompassing error handler. In other words, if there is no error handler configured at the level the error occurred then the error will be processed by the next level http://jaredsoablogaz.blogspot.com/2013/01/osb-error-handler-tutorial.html error handler. Below is an outline of how the error handlers are nested. Stage Node -> Pipeline -> Proxy Service -> System Error Handler Route Node -> Proxy Service -> System Error Handler Choosing an error handler action An Error Handler is not considered completely configured until it has a Resume or Reply Action configured. If an error handler is missing one of these actions then the other steps in the error handler will be completed but the error will be bubbled up to the next level error handler. Reply - Will immediately reply back to the calling process with an error response and all further message processing stops. Resume - Message flow process will continue as if no error occurred. The processing will continure after the node or stage that the error handler is configure in. Configuring Error Handlers Error handlers are just another pipeline and can be configured like any other pipeline. You may use an assign action, publish action…. Etc. In the error handler a new context variable is available ($fault). The $fault context variable contains information about any error that occurs during message flow processing and is populated before the error handler is invoked. For

Suppose you have a service in OSB with the following pipeline: This service will always raise an error and, as this is an WSDL based HTTP web service, this will translate into a SOAP Fault being returned to the called. The contents of the SOAP Fault will be dictated by OSB with some customization made in the Raise Error stage action as can be seen bellow: When calling this service (let's name it CalleeService), we get the following response (as expected): Now, let's try to route to the Callee Service from this new one. Let's call it Caller Service and its routing configuration should be like the one bellow: With the routing configured, let's try to call our new created Caller Service. You must be expecting to receive the same error thrown by Callee Service in respone, however, that's not what happens as can be seen bellow: OSB handles the error and returns a
