IBM Gift Center exception handling
When an exception occurs deep in the service layer, an ECException is thrown up the stack. The GiftRegistryComponentServiceImpl catches all non-runtime exceptions and processes them. If the ECException is not an ECApplicationException, then the exception is simply converted into a ServiceException and thrown to the WebSphere Commerce calling commands to handle. If the thrown exception is an ECApplicationException, then GiftRegistryComponentServiceImpl converts this exception to a confirm BOD and returns it to the calling command.
The following diagram depicts the error handing for the IBM Gift Center:
Conversion of a ECApplicationException to a ConfrimBOD is done automatically. A WebSphere Commerce action can call a helper method to inspect the confirm BOD and on error, throw another ECApplicationException. The following code excerpt illustrates this:
// Call the service and get the result updateResult = service.updateGiftRegistry(getUpdateGiftRegistryBOD()); // check the result GiftRegistryUtils.checkConfirmBODAndThrowExceptionOnError( updateResult, CLASS_NAME, methodName);
JSP files that include ErrorMessageSetup.jspf, as described above, handle errors and display appropriate error messages.
