unable to lookup Remote class in ejb3.0 using jboss6.1

[Blue heights]

Hi everyone,

can anybody help me out,
I am unable to lookup my remote class using jboss6.1 in ejb3.0.

		final String appName 		= "global";
		final String moduleName 	= "Calculator";
		final String distinctName 	= "";
		final String beanName 	= CalculatorBean.class.getSimpleName();
		final String viewClassName = CalculatorRemote.class.getName();
		final String distinctName 	= "";
		final String beanName 	= CalculatorBean.class.getSimpleName();
		final String viewClassName = CalculatorRemote.class.getName();

                final CalculatorRemote statelessRemoteCalculator =  (CalculatorRemote)context.lookup("ejb:" + appName + "/" + moduleName + "/" + distinctName + "/" + beanName + "!" + viewClassName);		
                result = statelessRemoteCalculator.add(a, b)

below is my stacktrace

[2014/04/22 23:05:17] java.lang.IllegalStateException: EJBCLIENT000025: No EJB receiver available for handling [appName:global, moduleName:Calculator, distinctName:] combination for invocation context org.jboss.ejb.client.EJBClientInvocationContext@15feec70

I had tried a lot.

one thing, when i debug the code i get
final CalculatorRemote statelessRemoteCalculator = {Calculator=Proxy for remote EJB StatelessEJBLocator{appName='app', moduleName='jboss-as-ejb-remote-app', distinctName='Calculator', beanName='CalculatorBean', view='interface com.tech.fest.CalculatorRemote'}}

is it right??
