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

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
