problem returning a response status

Reply Threaded

Hi everybody,

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???

Thanks

public void createUser(Representation entity) {
try {
// Parse the given representation and retrieve pairs of
// "name=value" tokens.
Form form = new Form(entity);
String userId=form.getFirstValue("userId");

myApplication.createUser(userId);

setStatus(Status.SUCCESS_CREATED, "Created User: " + userId);
} catch(Throwable e) {

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

}
}

Of course it would be better being able to threw the exception till the client, but if I'm not wrong that's not possible, is it??

Opinions appreciated...!!!

Thanks

Hi there,

Disclaimer: you're running RESTlet 2.0, with which I have very little familiarity.

With RESTlet 1.1, the way to specify a message within a status is to create a new instance of Status.

try:
setStatus(new Status(Status.SERVER_ERROR_INTERNAL, e.getMessage()));

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.

Hello Patrizio and Laurent,

about this that needs to be addressed.

Hi all,

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

"Add exception conversion to ConverterService"

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 Patrizio,

We try to reply to all messages in this list (see archives). We just can guarantee the order and the delay…

If you need timely assistance, you can consider our professional technical support offer:

http://www.noelios.com/products/support

I know that the Servlet API is tricky about this point. I would need to debug this to be sure it is a bug on our side. Could you send us a small application reproducing the issue?

Hello,

Patrizio Munzi a Ã©crit :

I'm trying to make work the following simple exception handling.

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 :

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????

Hello,
Patrizio Munzi a Ã©crit :
  
    
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

Hi Patrizio,

Servlet containers put some constraints in the way reason phrases are reported to the client. Basically, they don’t allow us to set the HTTP reason phrase.

They only give us a way (via HttpServletResponse# sendError(int sc, String msg) method) to include the Status#reasonPhrase property in the body of the HTML error page automatically generated by the Servlet container…
