Switch Guards
Hi! Our App has some Resources guarded by an Authenticator which uses our own Challenge Scheme (OAuth-Mac-Tokens). Now we also want to have clients, who can access the same resources but not using the Mac-Tokens, but plain Bearer-Tokens. The way i would do this, is to create a new Challenge Scheme and a second guard, and dynamically switch the guards before the route depending on what Challenge Scheme a request uses. Unfortunately I don't know if this is possible or how I can do this. Can somebody point me in the right direction?

SSL on Google App Engine
Hi! I want to secure my Rest-Application on the Google App-Engine by only allowing calls via HTTPS/SSL. Because i didn't really know how to do this, i first removed the HTTP-Connector from the list of available connectors in my web.xml. RestletServlet org.restlet.ext.servlet.ServerServlet org.restlet.application de.server.rest.ServiceApp org.restlet.clients HTTPS FILE It's still possible to access my webservice via plain HTTP though.

Bug in 2.1M5
Hi!
I have a ServerResource that looks like this:
@Post
public Representation store(Product product) {
ProductService service =
MyThreadLocal.getServiceFactory().productService();
if (null == getRequestAttributes().get("id")) {
Set> violations =
service.validate(product);
if (violations.size() == 0) {
product = service.create(product);
MyJacksonRepresentation response = new
MyJacksonRepresentation(product);
setStatus(Status.SUCCESS_CREATED);
return response;
} else {
setStatus(Status.CLIENT_ERROR_BAD_REQUEST);
JSONObject response = new JSONObject();
try {
response.put("error", "Validation of
this Product failed");
for (ConstraintViolation cv :
violations) {
response.append("Violations",
cv.getPropertyPath().toString() + " " +
cv.getMessage());
}
JsonRepresentation res = new
JsonRepresentation(response);
return res;
} catch (JSONException e) {
setStatus(Status.SERVER_ERROR_INTERNAL,
"Error generating the
Json-Error response.");
return null;
}
}
} else {
setStatus(Status.CLIENT_ERROR_BAD_REQUEST, "You must
not provide an id
when creating a new Product.");
return null;
}
}
When i use Restlet 2.1 Milestone5 and Post an invalid Product-Json, i get a
Response with a 400 Status Code (as expected), but an empty Response body.
However, if i use Restlet 2.0.8 i get the correct JSON Response.
Don't know what, but something seems to be wrong (or just different) in M5
that causes this behaviour...
Someone here knows what it could be?
Regards,
Sebastian

Hi Thierry,
unfortunately i din't get any zip file.
Yes i know i can write it like that, and it would work too.
But this way the headers are not set to application/json but to text/plain.
http://restlet-discuss.1400322.n2.nabble.com/IncompatibleClassChangeError-with-ConcurrentMap-tp6393712p6453417.html
See here.
When you run my code, is the field JsonValue in the JsonRepresentation set?
Best Regards,
Sebastian

Re: IncompatibleClassChangeError with ConcurrentMap
Hi, attached is a very simple code. I ran it on the local gae environment. When i create the JsonRepresentation, it's JsonValue is empty... That's not the same behaviour as in my other project, but maybe that's somehow causing the error.

Re: IncompatibleClassChangeError with ConcurrentMap
Sorry for posting multiple responses...when i have time i'll try to create a simple sample Project. Today i debugged further into it, and it just gets stranger. Until JsonRepresentation.write(Writer writer) all seems fine. writer.write() is called with the right JsonText at line 322. But after this my Text somehow gets lost in the depths of Java.io and i really don't see why. I also tried it on another pc, but it didn't work there either. When i change my ServerResource to return just the JSONObject, i get the Text output, but the MediaType is set to text/plain because the JsonConverter uses StringRepresentation. Is there a way to change the MediaType of the JsonConverter?

Hello Thierry,
i have to ask my person in charge tomorrow if it's alright to share some
sample code.
Some thing i noticed is that the size property of the JsonRepresentation is
set to -1.
Maybe that's the problem?
Here's what the JsonRepresentation looks like:
available=true
characterSet=UTF-8
encodings=[]
indenting=false
indentingSize=3
isTransient=false
jsonRepresentation=null
jsonValue=JSONObject {"count":2}
languages=[]
mediaType=application/json
size=-1

Hmm...of course that's not the problem either.
DefaultConverter is used for Representations,and it returns a valid
JsonRepresentation with a jsonValue set to my JSONObject.
That's returned by the ServerResource in doHandle() later and is also set as
the Response-Entity...
I'm really hitting the end of the road here.

What do you mean by sending the client code? Do you want to know which client i use to access the resource? That's Google Chrome atm. But i tried also with curl.

Thanks, but my JacksonRepresentation works fine. I just want to create some
small Json to send back some Error codes, or OAuth Tokens for example.

Tried adding the Annotation and overriding doInit()...nothing works.
But at least i think i found what's causing the error:
In the ConverterUtils class the method getBestHelper(Object source, Variant
target,UniformResource resource) is called and hence the DefaultConverter is
used instead of the JsonConverter...
I think what should be called is getBestHelper(Representation
source,Class target, UniformResource resource).
Don't know yet why it's called like this though.

Re: IncompatibleClassChangeError with ConcurrentMap
I don't want to seem impatient, but this is a crucial part of my bachelor's thesis, so i don't have that much time to solve it.

Running First Application
Hi! Im having some problems getting the First Application example to run. At first there was this http://restlet-discuss.1400322.n2.nabble.com/IncompatibleClassChangeError-with-ConcurrentMap-tp6393712p642.html issue . After upgrading the libs, i got this Error: [WARN] No available client connector supports the required protocols: 'FILE' . Please add the JAR of a matching connector to your classpath. Resolved it by removing the FILE Client-Connector from the web.xml. Now hitting the Get-Button gives me this: Can't parse the enclosed entity. So it looks like something went wrong within the Jackson extension. However, i couldn't find out what's causing the error so far. Has anybody else experienced this before?

Re: IncompatibleClassChangeError with ConcurrentMap
Hello Thierry,
Thanks, i haven't tried it yet but im sure it will work now.
However, since i added the new Snapshot to my Project, i don't get any
JsonObjects back with an JsonRepresentation...
My methods all look like this:
@Get
public Representation get(){
JsonRepresentation response = new JsonRepresentation(SomeJsonObject);
getResponse().setStatus(Status.SUCCESS_OK);
return response;
}
When called, all i get is an Empty page in my browser, not even empty curly
brackets.
Curl doesn't give me anything either.
The Status is correctly set, as well as the JsonRepresentation as the
Response's Entity though.
Any ideas?
Best Regards,
Sebastian

I had the same problem. If i remember correctly, i solved it by changing the Constructor of my Custom scheme.
