    Facing problem in RESTful webservice using RESTEasy

    Taimur Mirza Newbie

      Respected Fellows,


      I am trying to write a simple RESTful webservice using RESTEasy and have taken following steps


      1. I did not change my seam project's web.xml and components.xml


      2. Added  jaxrs-api-1.2.1.GA.jar, jboss-seam-resteasy.jar and resteasy-jaxrs-1.2.1.GA.jar to the .ear


      3. Added a new class in com.mc.dac.impexp.asset, which is as follow:





      import org.jboss.seam.annotations.Name;
      
      import javax.ws.rs.GET;
      import javax.ws.rs.Path;
      import javax.ws.rs.Produces;
       
      @Name("assetResource")
      @Path("/asset")
      public class AssetResource {
      
          @GET
          @Path("/{assetId}")
          @Produces("text/plain")
          public String getAsset() {
              return "Testing";
          }
      }





      Now when I start JBoss, it is successfully launched without any error but when I access this service using http://localhost/myapp/seam/resource/rest/asset/ I found following exception




      java.lang.NoClassDefFoundError: org/jboss/seam/resteasy/ApplicationConfig
      
      org.jboss.seam.resteasy.ResteasyResourceAdapter.getResourcePath(ResteasyResourceAdapter.java:54)
              org.jboss.seam.servlet.SeamResourceServlet.loadResourceProviders(SeamResourceServlet.java:55)





      Can someone help me like what I am missing? or is it some configuration related issue? I will really appreciate your help.

          Jozef,


          Thanks for your precious feedback, I am using Seam 2.1.1.


          I have read at some forums that RESTEasy webservices are compatible with Seam 2.2.x. Is this true?


          If yes, then I am slightly confused that if it was present in the earlier releases then how can it be possible that Seam 2.1.1 is not able to run a simple RESTEasy webservice.

            The support for JAX-RS web services has been evolving since 2.1.0. I am not aware of it being that broken in any official release.

              I have updated jars but now when I start JBoss I found following exception:
