Re: Problem with virtualHost
Hello Jean-Christophe,
I think you should use the other VirtualHost constructor, that is to say
the one with the parent context:
VirtualHost host = new VirtualHost(component.getContext());
best regards,
Thierry Boileau
Hi,
I have a problem with virtualHost.
The following code works :
public static void main(String[] args) {
try {
final ConfigFile conf = new ConfigFile();
// Create a new Component.
Component component = new Component();
// Add a new HTTP server listening on port 8182.
component.getServers().add(Protocol.HTTP, conf.getPort());
component.getClients().add(Protocol.FILE);
Application application = new Application() {
@Override
public Restlet createRoot() {
Directory directory = new Directory(getContext(),
conf.getRoot_uri());
directory.setListingAllowed(true);
directory.setModifiable(false);
directory.setDeeplyAccessible(true);
return directory;
}
};
// Attach the application.
component.getDefaultHost().attach(application);
// Start the component.
component.start();
} catch (Exception e) {
// Something is wrong.
e.printStackTrace();
}
}
but the following code does not work :
public static void main(String[] args) {
try {
final ConfigFile conf = new ConfigFile();
// Create a new Component.
Component component = new Component();
// Add a new HTTP server listening on port 8182.
component.getServers().add(Protocol.HTTP, conf.getPort());
component.getClients().add(Protocol.FILE);
Application application = new Application() {
@Override
public Restlet createRoot() {
Directory directory = new Directory(getContext(),
conf.getRoot_uri());
directory.setListingAllowed(true);
directory.setModifiable(false);
directory.setDeeplyAccessible(true);
return directory;
}
};
// Attach the application.
VirtualHost host = new VirtualHost();
host.setHostDomain(conf.getHostname());
host.setHostPort(String.valueOf(conf.getPort()));
host.attach(application);
// Attach the host to the component.
component.getHosts().add(host); //host = localhost|my IP
component.updateHosts();
// Start the component.
component.start();
} catch (Exception e) {
// Something is wrong.
e.printStackTrace();
}
}
I do not understand why the second code does not work. Anyone can
explain me please ?
Thanks,
J-Christophe

Re: Gzip on netty
Hi kiwi,
the gzip encoding of the entity is available via the Encoder filter.
For example, when declaring your application:
public Restlet createInboundRoot() {
Router router = new Router(getContext());
router.attachDefault(HelloWorldResource.class);
[...]
Filter filter = new Encoder(getContext());
filter.setNext(router);
return filter;
}
It will encode the provided entity according to the client's preferences.
Best regards,
Thierry Boileau
hi,
I just setup a rest app that use Netty as front end.
however, it seem like is not g-zip enabled by default.
how can i configure it and test it out ?

Re: XML format in ATOM content element
Hello Rob,
at this time the XMl writer consider the content element as simple
text in any case (in the most general case, it can contain both text and
XML elements) without taking care of formatting options.
However, it is possible to use formatting in the special case of XML
content. I've entered a new issue for that:
http://restlet.tigris.org/issues/show_bug.cgi?id=975
Best regards,
Thierry Boileau
Hi,
I am trying to use the Restlet ATOM extension and I cannot figure out why
I am losing the formatting of my content element in the Atom document I am
creating. Here is a piece of code from my class that extends ServerResource:
public Representation getAtomFeed() throws IOException {
Feed f = new Feed();
MapString, String attrs;
f.setTitle(new Text(MediaType.TEXT_PLAIN, Feed Title));
f.setId(some identifier);
Person p = new Person();
p.setName(me);
f.getAuthors().add(p);
Generator gen = new Generator();
gen.setName(RESTlet);
gen.setUri(new Reference(http://www.restlet.org;));
gen.setVersion(2.0M6);
f.setGenerator(gen);
f.setUpdated(new Date());
//Add feed links
//...
//Perform query that returns a map of strings.
attrs = something.getAttributes(someValue);
Entry entry = new Entry();
entry.setUpdated(new Date());
entry.setId(identifier);
Content c = new Content();
c.setToEncode(false);
c.setInlineContent(new SaxRepresentation(MediaType.APPLICATION_XML) {
@Override
public void write(XmlWriter writer) {
for(Map.EntryString, String e : attrs.entrySet()){
try {
writer.dataElement(e.getKey(), e.getValue() == null ?
: e.getValue());
} catch (SAXException e1) {
e1.printStackTrace();
}
}
}
});
entry.setContent(c);
//Add entry links
//...
f.getEntries().add(entry);
return f;
}
Here is the ATOM feed that this code creates:
?xml version=1.0 standalone='yes'?
feed xmlns=http://www.w3.org/2005/Atom;
author

Is there a way to correct this format issue or I am completely off base with
my resource code. Any help is appreciated.

Re: Empty HTTP WWW-Authenticate header in response
Hello Yu, I think that your helper is either not recognized or does not specify correctly the serverSide attribute. Could you check that serverSide attribute is set to true, and that the Engine registers correctly your helper (check the Engine.getInstance().getRegisteredAuthenticators() list)? Best regards, Thierry Boileau Hi, I implemented a custom Guard that handles multiple authentications, e.g. HTTP Simplem, Amazon S3 (my own AmazonS3ServerHelper implementation), etc. According to HTTP spec., the server responses the WWW-Authenticate header(s) when credentials are not provided in the request. So my code had lines like: final ListChallengeRequest list = new CopyOnWriteArrayListChallengeRequest(); list.add(new ChallengeRequest(ChallengeScheme.HTTP_BASIC, HTTP Simple Authentication)); list.add(new ChallengeRequest(ChallengeScheme.HTTP_AWS_S3, Amazon S3 Authentication)); //list.add(new ChallengeRequest(ChallengeScheme.HTTP_AWS, Amazon S3 Authentication)); list.add(new ChallengeRequest(ChallengeScheme.HTTP_OAUTH, HTTP OAuth Authentication)); response.setChallengeRequests(list); However, the HTTP response looks like: HTTP/1.1 401 Unauthorized Server: Apache-Coyote/1.1 Date: WWW-Authenticate: Basic realm=MRSP Simple Authentication WWW-Authenticate: WWW-Authenticate: OAuth realm=HTTP OAuth Authentication Accept-Ranges: bytes ... The header value for Amazon S3 was empty. Does anyone know what and where it's wrong?

Hello
Is it possible to authenticate a request via the RIAP protocol? One of

Re: IE 8 HTML request not working
Hello Fabian and Erick,
thanks to your report, I've relaxed the checks made on the agent
properties which was based on a string comparison sensible to the case.
Now, the comparison ignore the case which should enable you to use the
tunnel filter.
The code is available in the svn repository and will be available in the
next snapshot.

I've enabled the TunnelService (Restlet 2.0M5, still didn't switch to

Re: Unauthenticated access returns 204.
I've always thought that 401 Not Authorized was poorly chosen wording, because it really says the same thing as 403 Forbidden. However, the requirement that a 401 status also MUST send a WWW-Authenticate header I think in practice has led 401 to really mean Not Authenticated and 403 to really mean Not Authorized. Whereas in the description of 403 in rfc2616 section 10 explicitly states that Authentication will not help, which implies that either no authentication is possible, the user is simply trying to do something the server doesn't want done, or it implies that the user is in fact authenticated, and the server is saying the authenticated user isn't authorized to do that. So where does that leave us? I guess I think that the abstract implementation of Authenticator should not simply return 204 to the client if Authentication has been set to be required, and a concrete subclass has returned false in the authenticate() method. It is OK, because it does in fact stop the filter, but I think it could be a little bit easier on the programmer implementing the concrete subclass. Perhaps setting the status to 403 is more appropriate in this case. Anyway, I trust the restlet team's judgement here, but if you decide to keep the behavior as it is, then I encourage you to document clearly that the unauthenticated() method will also need to be overridden in subclasses in order to produce behavior that results in a 401 or 403 upon returning false from the authenticate() method. I would be happy to look at possible implementations of changing the default behavior if it is something the restlet team thinks would be worthwhile. The good news is that as far as my current project goes, I have custom subclasses of Authenticators and Authorizers working very well and I really like the new security architecture, I'm just trying to figure out if this particular aspect of the behavior is as simple as it could be.
