AppException was introduced just to serve this needs. It is handled in other way as all other exceptions. Please have a look at LogonAction in:
http://www.mail-archive.com/struts-dev@jakarta.apache.org/msg04149.html Dmitri >The reason I want to use Exceptions is because currently I am using >LookupDispatchAction, and I have 2 methods, add & save, that both call >the "UploadFile" method. Currently, the UploadFile method returns >ActionErrors, but it seems to be better coding to have "void uploadFile >throws UploadFileException", rather than "ActionErrors uploadFile". >The current architecture seems to limit 1 exception to only throw 1 >message key - being that you define this 1 message key in >struts-config.xml. What I would like is to throw an exception with a >(key, value) and having this key be used for the exception message. >So in my UploadAction class, rather than having: > if (fileName == null || fileName.length() == 0) { > logCat.error("validation error: no file specified"); > errors.add(ActionErrors.GLOBAL_ERROR, > new ActionError("errors.required", > resources.getMessage("label.mediaFile"))); > return errors; > } > >I'd like to do: > > if (fileName == null || fileName.length() == 0) { > throw new FileUploadException("errors.required", > >resources.getMessage("label.mediaFile")); > } > >My FileUploadException is: > >public class FileUploadException extends AppException { > > /** > * Construct a new instance of this exception for the specified >filename. > * > * @param key Key that contains the error message key > * @param param Parameter value for insertion into message > */ > public FileUploadException(String key, String param) { > super(key, param); > } >} -- Diese E-Mail enthält vertrauliche und/oder rechtlich geschützte Informationen.
