IllegalArgumentException: No mainInterface: otherwise di: BeanContext(id=ServerStateImpl) InterfaceType: BUSINESS_REMOTE_HOME interfaces: [null]

Hello!
I use EJB for managing server state for client side regression tests. When I 
run client side tests with Arquillian, all test pass, but I receive exception 
on deployment time: https://pastebin.com/ybC8Hs1a
Why I recevie this exception?

This my remote interface:

@Remote
public interface ServerState {

    public void load(Collection<StateAction> stateActions) throws Exception;

    public void clean();

    public void setSession(String sessionId, int sessionMaxInactiveInterval);
    
}

This my EJB:

@Stateful(mappedName = "MyServer")
public class ServerStateImpl implements ServerState {

    @Override
    @Transactional
    public void load(Collection<StateAction> fromClient) throws Exception {
      // do something
    }

    @Override
    @Transactional
    public void clean() {
        // do something
    }
    
    @Override
    public void setSession(String sessionId, int sessionMaxInactiveInterval) {
       // do something
    }

    public void otherMethod() {
        // do something
    }
}

This my lookup code:

@RunWith(Arquillian.class)
@RunAsClient
public class MyTest {
    
    private ServerState serverState;
    
    @Deployment(testable = false)
    public static WebArchive createDeployment() {
      ...
    }

    @Before
    public void init() {
      Properties p = new Properties();
      p.put("java.naming.factory.initial", 
"org.apache.openejb.client.RemoteInitialContextFactory");
      InitialContext ctx = new InitialContext(p);
      myServer = (ServerState) ctx.lookup("MyServer");
    }

    ...
}

Thank you!
