Hi Ghania, To debug any rest interface, you could use the rest api plugin for chrome. This enables you to query any rest api on the fly, without programming the client side yourself. Probably something similar is also available for Firefox, but I never tried to find that.
if you understand the details of the api in this way, you can implement it in your code afterwards.

Datum: ma, sep. 9, 2013 18:09 Hi Mike and Thank you very much for your response :) I tried "left" and "right" instead of "leftEndpoint" and "rightEndpoint", as parameters in the form, but it is still not working with the same error message. I even created an other java client ( not using jersey) to communicate with REST API of ACE, no luck.. Is there a more suitable Client REST API than Jersey ? A sample of code will really help. Thank you again for your response, My best Regards, Ghania ________________________________ De : Mike van Dongen <[email protected]> À : "[email protected]" <[email protected]> Envoyé le : dimanche 8 Septembre 2013 16h24 Objet : RE: How to query the distributions/targets with the Client Rest API?

Once a new workspace is created, the client will be redirected to this workspace.The URL you're being redirected to is "client/work/rest-ID", where rest-ID is the ID of your workspace.In my case I was able to retrieve the URL that was last used and set it as the base URI. I'm unfamiliar with Jersey but this might help:https://jersey.java.net/nonav/apidocs/1.1.1-ea/jersey/com/sun/jersey/api/client/WebResource.html#getURI() Good luck!Mike. > Thank you again for your response, > My Best Regards, > Ghania > > > > ________________________________ > De : Elmar Zeeb <[email protected]> > À : [email protected] > Envoyé le : vendredi 6 Septembre 2013 3h15 > Objet : Re: How to query the distributions/targets with the Client Rest API? > > > Hi Ghania, > > Am 05.09.2013 19:04, schrieb ghania ferrag: > > Hi all, > > > > I’m working on new web UI ( I used Vaadin for this UI) to allow our users > > to send distributions to specific targets. > > In our UI we have just to display all existing distributions and I wonder > > how to query the distributions with the Client Rest API? > > I read the following link: > > https://cwiki.apache.org/confluence/display/ACE/Client+REST+API > > > > > > > > Some one can tell me what is wrong with this REST-client code (I used > > Jersey): > > 1) I suspect the path is wrong: "ace/workspaceID/distribution" ? > > 2) or may be REST-server is not set ? > > > > import javax.ws.rs.core.UriBuilder; > > import com.sun.jersey.api.client.Client; > > import com.sun.jersey.api.client.WebResource; > > import com.sun.jersey.api.client.config.ClientConfig; > > import com.sun.jersey.api.client.config.DefaultClientConfig; > > public class ClientTest{ > > public static void main(String[] args) { > > getDistributions(); > > } > > > > public static void getDistributions() { > > ClientConfig config = new DefaultClientConfig(); > > Client client = Client.create(config); > > WebResource service = client.resource(getBaseURI()); > > // Get JSONfor application > > > > System.out.println(service.path("workspaceID").path("distribution").accept(MediaType.APPLICATION_JSON).get(String.class)); > > // Get XML for application > > > > System.out.println(service.path("workspaceID").path("distribution").accept(MediaType.APPLICATION_XML).get(String.class)); > > } > > private static URI getBaseURI() { > > return UriBuilder.fromUri("http://localhost:8080/ace";).build(); > > } > > > > Thanks and Regards, > > Ghania > You should create a association between a distribution and a target, > this is called distribution2target and is a resource that can be created > with a post to ace/workspaceID/distribution2target (see > http://ace.apache.org/user-doc/restapi.html). > > Regards, > Elmar
