No EJB receiver available for handling ...
Jboss EAP 6에서 원격 EJB를 호출할 때 이 오류가 발생했습니다. 왜냐하면 JNDI 형식이 잘못 썼기 때문입니다.EJB JNDI의 형식은 다음과 같습니다.
 
ejb:///!?stateful
 
appName 앞에는 "/"이 없습니다.distinctName이 없으면 비어 있습니다. 즉, 두 개의 "//"연속입니다.
 
jboss-eap-quickstarts-6.4.0.GA는 예제 코드 jb-remote를 제공합니다:
 

public interface RemoteCalculator {

    int add(int a, int b);

    int subtract(int a, int b);
}

@Stateless
@Remote(RemoteCalculator.class)
public class CalculatorBean implements RemoteCalculator {

    @Override
    public int add(int a, int b) {
        return a + b;
    }

    @Override
    public int subtract(int a, int b) {
        return a - b;
    }
}

public class RemoteEJBClient {

    public static void main(String[] args) throws Exception {
        // Invoke a stateless bean
        invokeStatelessBean();

        // Invoke a stateful bean
        invokeStatefulBean();
    }

    private static void invokeStatelessBean() throws NamingException {
        // Let's lookup the remote stateless calculator
        final RemoteCalculator statelessRemoteCalculator = lookupRemoteStatelessCalculator();
        System.out.println("Obtained a remote stateless calculator for invocation");
        // invoke on the remote calculator
        int a = 204;
        int b = 340;
        System.out.println("Adding " + a + " and " + b + " via the remote stateless calculator deployed on the server");
        int sum = statelessRemoteCalculator.add(a, b);
        System.out.println("Remote calculator returned sum = " + sum);
        if (sum != a + b) {
            throw new RuntimeException("Remote stateless calculator returned an incorrect sum " + sum + " ,expected sum was "
                    + (a + b));
        }
        // try one more invocation, this time for subtraction
        int num1 = 3434;
        int num2 = 2332;
        System.out.println("Subtracting " + num2 + " from " + num1
                + " via the remote stateless calculator deployed on the server");
        int difference = statelessRemoteCalculator.subtract(num1, num2);
        System.out.println("Remote calculator returned difference = " + difference);
        if (difference != num1 - num2) {
            throw new RuntimeException("Remote stateless calculator returned an incorrect difference " + difference
                    + " ,expected difference was " + (num1 - num2));
        }
    }

예는 jboss에 jboss 패키지로 배치된 것입니다. jboss 로그를 보면 다음과 같은 것을 찾을 수 있습니다.
java:jboss/exported/jboss-ejb-remote-server-side/CalculatorBean!org.jboss.as.quickstarts.ejb.remote.stateless.RemoteCalculator
 
jar 패키지 형식으로 배치, 접근 시 쓰기:

context.lookup("ejb:/jboss-ejb-remote-server-side/CalculatorBean!" + RemoteCalculator.class.getName());

나는 그것을 ear로 옮겨서 다음과 같이 썼다.

context.lookup("ejb:/myear/myejb/CalculatorBean!" + RemoteCalculator.class.getName());

참고: 기본적으로 WildFly는 8080을 리모팅 포트로 사용합니다.The EJB client API uses the http port, with the http-upgrade functionality, for communicating with the server for remote invocations(unless the server is configured for some other http port)
