    ModelControllerClient errors in Faban service. Provider org.xnio.nio.NioXnioProvider could not be instantiated: java.lang.NoSuchFieldError: TRACE

    Will Reichert Newbie

      I am trying to setup a Faban Service that will start and stop Jboss AS7 Standalone as well as perform some administration using the ModelControllerClient. The code works when launched within Eclipse with the following Jar dependencies

       

      ./services/JbossAs7Service/lib/jboss-marshalling-1.3.14.GA-redhat-1.jar
      ./services/JbossAs7Service/lib/jboss-threads-2.0.0.GA-redhat-1.jar
      ./services/JbossAs7Service/lib/commons-cli-1.2-redhat-1.jar
      ./services/JbossAs7Service/lib/jboss-sasl-1.0.1.Final-redhat-1.jar
      ./services/JbossAs7Service/lib/jboss-remoting-3.2.8.GA-redhat-1.jar
      ./services/JbossAs7Service/lib/jboss-as-controller-client-7.1.2.Final-redhat-1.jar
      ./services/JbossAs7Service/lib/xnio-api-3.0.4.GA-redhat-1.jar
      ./services/JbossAs7Service/lib/jboss-as-protocol-7.1.2.Final-redhat-1.jar
      ./services/JbossAs7Service/lib/jboss-dmr-1.1.1.Final-redhat-1.jar
      ./services/JbossAs7Service/lib/jboss-logging-3.1.1.GA-redhat-1.jar
      ./services/JbossAs7Service/lib/JbossAs7Service.jar
      ./services/JbossAs7Service/lib/xnio-nio-3.0.4.GA-redhat-1.jar
      

       

      However when the jars are bundled with the Service code and deployed to Faban the harness is unable to execute the ModelControllerClient because of the following exception:

       

      java.util.ServiceConfigurationError: org.xnio.XnioProvider: Provider org.xnio.nio.NioXnioProvider could not be instantiated: java.lang.NoSuchFieldError: TRACE

      org.service.JbossAs7Service  getClient  245
      
      

       

      The code for JbossAs7Service.getClient is the following:

       

        private ModelControllerClient getClient(String host,int port,String username,String password,String securityRealm) throws UnknownHostException{
          ModelControllerClient rtrn = null;
          InetAddress serverHost = InetAddress.getByName(host);
          ModelControllerClient unauthenticatedClient = ModelControllerClient.Factory
              .create(serverHost, port);
          try{
            ModelNode testConnection = new ModelNode();
            testConnection.get("operation").set("read-resource");
            unauthenticatedClient.execute(testConnection); //this is line 245 <~~~~~~~~~~~~~~~~~~
            rtrn = unauthenticatedClient;
          }catch(Exception e){
            logger.log(Level.SEVERE, "Exception trying unauthenticated",e);
            rtrn = createClient(serverHost,port,username,password,securityRealm);
          }
          return rtrn;
        }
      

       

      Any help in determining why the Provider cannot be instantiated or which class defines TRACE (or should define TRACE but apparently does not) would be greatly appriciated.
