I just started to learn RESTlet framework and I am facing some strange issue I can't handle. I've created the simple resource, which verifies if such user exists and if so - returns the unique hash for the user. I also wrote the simple test case, which starts the REST service and then sends the request to authenticate the user. At this point there is the strange issue appearing: when DomRepresentation is used, the test simply hangs on valid user (when the response is sent), but when StringRepresentation is used - everything works fine. The code for the Service: ============================================================================================ import org.apache.log4j.Logger; import org.restlet.Context; import org.restlet.data.Form; import org.restlet.data.MediaType; import org.restlet.data.Request; import org.restlet.data.Response; import org.restlet.data.Status; import org.restlet.resource.DomRepresentation; import org.restlet.resource.Representation; import org.restlet.resource.Res Eugeny N Dzhurinsky 2008-11-29T21:40:00 http://comments.gmane.org/gmane.comp.java.restlet/6980 Hi all (my first post), my question is concerning file upload within a form. I'm currenlty using Restlet 1.1.1. I have both client and server developed with Restlet. I'd like to make a post call, sending 2 (key, value) pairs and a file. I success this by making 2 post calls, one for the 2 (key, value) pairs, simply using a Form and its WebRepresentation, and one for the file, using a FileRepresenation (with a MediaType.APPLICATION_OCTECT_STREAM, as my file could be a binary one or a text one -it's a certificat-). That's works. My question : is it possible to make only 1 post call including the 2 (key, value) pairs and the file (which can be binary or plain text) ? Thanks in advance and sorry if my english isn't so clear :) Regards, Jérémy Jérémy Bogatirsky 2008-11-26T16:33:55 http://comments.gmane.org/gmane.comp.java.restlet/6965 When I try to download the sample sources, http://www.restlet.net/source/browse/restlet/trunk/modules/org.restlet.example/src/org/restlet/example/dist/testServlet.zip, referenced on the Restlet 1.1 - User FAQ page, I get the following not found message: The requested URL /source/browse/restlet/trunk/modules/org.restlet.example/src/org/restlet/example/dist/testServlet.zip was not found on this server. Does anyone know if it has moved, and if so, where? Thanks in advance. Mark Rosenthal 2008-11-25T22:37:49 http://comments.gmane.org/gmane.comp.java.restlet/6964 Hi all, I was starting to code a set of Resource classes which implement the Atom Publishing Protocol, and wanted to use the org.restlet.atom.ext extension, but it looks like this implements an older version. For example, the Collection class still uses the "member-type" element of app:collection, which hasn't existed since draft 8. Here are links to the latest version (RFC 5023) as well as the older drafts: http://bitworking.org/projects/atom/ I'll be glad to help out implementing the latest version of the spec if needed. Thanks, Thom Thom Nelson 2008-11-25T22:29:19 http://comments.gmane.org/gmane.comp.java.restlet/6963 Thierry, et al, I have been working with the "Directory" class, and running into limitations. I realized that because I am also running Tomcat, the built-in webdav met my needs. However--and because you were asking for suggestions--I realized that the Directory class could easily be improved: 1) Allow for stylesheets, see Tomcat's WebdavServlet setup (localXsltFile, and globalXsltFile). Note that a URI (instead of a path) would be even better. 2) Have the default representation return XHTML (instead of the current nonX HTML). This would allow a programmatic caller to read the list as XML (a request from one of my users). 3) Add a simple authorization hook, or at least clearly describe how to authorize access to certain directories. Note that even in Tomcat, I had to go digging through the code to figure out how to subclass. 4) Add full webdav capability. Given that WebdavServlet is Apache License--and not very big--it seems that you could easily support full webdav out of the box.

Thanks in advance Gan123 2008-11-24T14:07:50 http://comments.gmane.org/gmane.comp.java.restlet/6954 Among EHCache and Memcache which is the best one to choose for restful application to work with distributed caching? Gan123 2008-11-24T13:10:42 http://comments.gmane.org/gmane.comp.java.restlet/6943 Hello, I'm observing an odd situation where restlet is involved: pull the net cable during file upload and router (hardware box, not Router.class) detects TCP RST attack and blacklist our server for access from subnet. This is the topology: - office subnet: client application - office router: NAT - remove server: Apache HTTPS proxying to localhost - remove server: Restlet with default HTTP connector The behavior can be consistently reproduced with our setup and access to remote server is temporarily blocked to entire office subnet. The client application makes a GET and then a POST w/ a big file, so that I have time to pull the plug, and that's it. I tried reading a bit about TCP RST attack but so far I do not know how to avoid this problem, except for disabling the attack detection in the router or telling people not to pull the plug during upload. If anybody has some insights to share, I appreciate. Thanks, Diego Diego Ballve 2008-11-22T07:59:21 http://comments.gmane.org/gmane.comp.java.restlet/6940 I would like to modify the standard Directory to return something different than "the" file when a file is encountered. For example, peruse a directory structure (default behavior), but when you get to the "bottom" (an actual file), then return a report based on that file, instead of the file itself. It appears that I need a custom "DirectoryResource" which is attached to a "Directory" via #setTargetClass. I have the following questions: 1.Setting the target class doesn't seem to be invoking the resource 2.I'm not sure what I would need to override to have custom behavior: #getVariants? 3.Is there a better way to approach the problem? Thanks in advance, Cliff Cliff Binstock 2008-11-21T22:53:48 http://comments.gmane.org/gmane.comp.java.restlet/6933 Hi, Just started exploring restlet and trying to implement a simple employee details info management app. it have two pages, one to create a new employee. second that lists all employees. once the employee is created the resource should be redirected to other resource which will list all the employees. how i could do this either by giving URI or by giving second resource ref in 1st resource? Thanks in advance. Gan123 2008-11-21T15:01:01 http://comments.gmane.org/gmane.comp.java.restlet/6920 i am creating a web application using Restlet based on MVC. i have configured ServlerServlet to invoke my Application class, where i have all the URI mappings. i am planning to use the Application class as controller and Resource to implement business logic with other required patterns. can any one suggest me whether this is the correct way to go ahead to implement MVC application in RESTlet? how and when the Application will be loaded? is it for every request or once per application ? Thanks in advance. Gan123 2008-11-21T07:09:59 http://comments.gmane.org/gmane.comp.java.restlet/6918 Hi there, i am curious, is there any way to get the _real_ client address from Request.getClientInfo()? I am talking about the situation, when you have your Restlet App (whether standalone, or running in Servlet Container) fronted by mod_proxy + httpd... Something like this (example found on the net, in PHP): http://www.zen-cart.com/forum/showpost.php?p=437632&postcount=8 The ClientInfo.getAddresses() "smells" like right place to sniff around, but i don't get the Javadoc and what it really does.... Tamás Cservenák 2008-11-20T18:41:53 http://comments.gmane.org/gmane.comp.java.restlet/6911 Hi I'm testing my system to see how it handles a DELETE request to a non-existent resource. I'm expecting a 404 response. Although I'm flagging my resource as unavailable in the constructor/init method removeRepresentations still gets invoked, which means I have to explicitly handle the 404 response. Is this the correct behaviour?

Any interest? -jeff Jeff Ramsdale 2008-11-19T00:24:42 http://comments.gmane.org/gmane.comp.java.restlet/6894 Hi THE SHORT VERSION: I'm using version 1.1.1. I post an entity with an ETag using org.restlet.Client and get a null ETag in acceptRepresentation. This happens with Tomcat but not with the standalone Restlet test. I can't find any code that looks like it would handle the propagation of the tag. I've tried using a custom header as a workaround but that has no effect either. This is critical for my project. Please help THE LONG VERSION: I'm trying to test a resource that uses an ETag when accepting a representation. Using org.restlet.Client: Request request = new Request(Method.POST, "http://localhost:8080/tag-test"); request.getClientInfo().getAcceptedMediaTypes().add(new Preference<MediaType>(MediaType.APPLICATION_JSON)); request.setEntity("some text", MediaType.APPLICATION_JSON); request.getEntity().setTag(new Tag("tag text")); Client client = new Client(Protocol.HTTP); Response response = client.handle(request); When acceptRepresentation is called, there is no sign of the ETag: public void a Richard Hoberman 2008-11-17T22:44:44 http://comments.gmane.org/gmane.comp.java.restlet/6893 I've been seeing a lot of: ERROR: 'Broken pipe' Exception intercepted < at > HttpServerConverter.commit lately. What exactly does it mean? How can I print out the exception? And possible how to debug this? I'm using Restlet 1.0.9. - Paul Paul J. Lucas 2008-11-17T21:51:52 http://comments.gmane.org/gmane.comp.java.restlet/6885 WANNING BRAIN OVERHEATING  /\ I have read this http://en.wikipedia.org/wiki/Https and I want to implement HTTPS, in my sample application I converted component.getServers().add(Protocol.HTTP, 8182);to component.getServers().add(Protocol.HTTPS, 8182); Now Jersy is asking me a lot of questions in the shell (key and pass),  I guess the answer and I wrote "me" as an answer for both questions!! /home/java/.keystore is not found and Exception is thrown... Is .keystore our Public Key Certificate, if yes, Is it created using gensslcert?? and where is the private key?  if HTTPS is authenticating both sides (as I hardly understand) then there must be one or two public keys and two private keys so server can authenticate client and client can authenticate browser. the browser will authenticate the server because server will send private key, (automatically I hope), if this is true how the server will authenticate the browser... MOST important question how I get all of this implemented, Is there somethi M E 2008-11-17T14:30:37 http://comments.gmane.org/gmane.comp.java.restlet/6878 Hi I added an HTTP server on port 80 using Restlet, it does NOT work, however it works on port 8080, why?? java.net.SocketException: Permission denied  it seems to be the first cause exception My guesses I don't get it, browser suppose to listen to port 80 for http, or it just a firewall issue, but it is localhost ip, further if it is firewall, how 8182 work without setting a rule!! hmmm, I guess I don't get it!! Thanks M E 2008-11-17T11:00:12 http://comments.gmane.org/gmane.comp.java.restlet/6877 Hi If I make a request using an empty string: Request request = new Request(Method.POST, "http://localhost:8080/..."); request.getClientInfo().getAcceptedMediaTypes().add(new Preference<MediaType>(MediaType.APPLICATION_JSON)); request.setEntity("", MediaType.APPLICATION_JSON); my accept method will receive an entity with a null mediaType: public void acceptRepresentation(Representation entity) throws ResourceException { MediaType mediaType = entity.getMediaType(); // will be null .... } Simply adding a space to the string (i.e. " ") results in the correct media type. This behaviour occurs when I deploy the application on Tomcat, but not when run in standalone mode. I've attached a bare-bones Tomcat webapp demonstrating this behaviour and a test case showing that it does not occur when run in standalone mode. From what I can make out, when the entity is "", getRequestHeaders is returning 0 parameters at line 173 of HttpServerCall (revision 3882) but it is not clear to me Richard Hoberman 2008-11-17T09:49:42 Search the mailing list at Gmane query http://search.gmane.org/?group=$group=gmane.comp.java.restlet
