Re: problem returning a response status

Thu, 10 Sep 2009 05:51:57 -0700

Hi everybody,

I think there's a bug or at least something strange in ResourceException management.
The getDescription method works only if I run my application in a stand-alone server.
It instead doesn't work if I run in a servlet container (tomcat 5.5).

I'm throwing the following exception server-side:
----------------------------------------------
        } catch(Throwable e) {
            throw new ResourceException(Status.SERVER_ERROR_INTERNAL, e.getMessage, e);
       }
----------------------------------------------

And here's my client code:
----------------------------------------------
        try {
            Form form = new Form(); 
            form.add("userId", userId); 
            Representation userRepresentation = form.getWebRepresentation();

            Request createUserRequest = new Request(Method.POST, createUrl);

            createUserRequest.setEntity(userRepresentation);
            Response response = client.handle(createUserRequest);
            resultStatus = response.getStatus();
        } catch (Throwable t) {
            System.err.println("Exception in creating User: " + userId + ". Exception: " + t);
        }       
        if (resultStatus.isSuccess()) { 
            System.out.println("Created User: " + userId + ". Status: " + resultStatus.getName() + " - Description: " + resultStatus.getDescription());
        }
        else {
            System.err.println("Error in creating User: " + userId + ". Status: " + resultStatus.getName() + " - Description: " + resultStatus.getDescription());
        }
----------------------------------------------

II the application runs in a servlet container I get the following message client side:

Error in creating User: TestUser. Status: Internal Server Error - Description: OK

instead in a stand alone server I get the right description:

Error in creating User: TestUser. Status: Internal Server Error - Description: Test Exception

Has anyone got any idea if it's a bug or I'm doing something wrong????

Thanks

Hi all,

Regarding the propagation of exceptions on the client-side, I've got some plans there:

"Add exception conversion to ConverterService"

Hello Patrizio  and Laurent,


you're right Laurent. I notice also there is a lack of documentation 
about this that needs to be addressed.

Hello,
Patrizio Munzi a écrit :
  
    
I'm trying to make work the following simple exception handling.
I just want to return the status specified.
The problem is that client side I cannot retrieve nothing, neither the exception or the exception message.

I'm surely doing it wrongly, but I haven't find any written explanation on how managing exception.

Could someone give me some hints to the right way???
    
      
I think you can do the following in your catch block :
throw new ResourceException(Status.SERVER_ERROR_INTERNAL, e);
If it is not enough, try to extend StatusService class. More info in 
this thread 
http://restlet.markmail.org/message/ptesti33kkk5bksv?q=StatusService
Hope it help.
Regards,
Laurent.

  
    
Thanks

e.printStackTrace();
setStatus(Status.SERVER_ERROR_INTERNAL, e, e.getMessage());
