What is the JNDI name should I use to lookup for a remote interface deployed in websphere using Spring Boot?

Question

I have a remote interface deployed in websphere 8.5.5 and I want to look up for this in spring boot application. I have made similar interface in my spring boot as common interface RMI I also used SimpleRemoteStatelessSessionProxyFactoryBean but the proxy returned is null and it was throwing null pointer in proxy.invokeMethod()

@Configuration
public class Config {

    private static final String INITIAL_CONTEXT_FACTORY = "com.ibm.websphere.naming.WsnInitialContextFactory";
    private static final String PROVIDER_URL = "corbaname:iiop:localhost:2809/NameServiceServerRoot";

    @Primary
    @Bean
    public static AdminService adminService() {

        Properties jndiProps = new Properties();
        Properties properties = new Properties();
        properties.put(Context.INITIAL_CONTEXT_FACTORY, INITIAL_CONTEXT_FACTORY);
        properties.put(Context.PROVIDER_URL, PROVIDER_URL);

        SimpleRemoteStatelessSessionProxyFactoryBean factory = new SimpleRemoteStatelessSessionProxyFactoryBean();
        factory.setJndiEnvironment(jndiProps);
        factory.setJndiName("java:global/[AppName]/[ModuleName]/ejb/[BeanName]![RemoteInterface]");
        factory.setBusinessInterface(AdminService.class);
        factory.setResourceRef(true);
        AdminService proxy = (AdminService) factory.getObject();
        try {
            proxy.invokeMethod();
        }catch(RemoteException e) {
            e.printStackTrace();
        }

        return proxy;       
    }
}

Now it's throwing this error:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'AdminService' defined in class path resource [...Config.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [...AdminService]: Factory method 'adminEJBService' threw exception; nested exception is javax.naming.NameNotFoundException: Name [global/[AppName]/[ModuleName]/ejb/[BeanName]![RemoteInterface] is not bound in this Context. Unable to find [global].

You must replace everything in [] with the actual name, so not [AppName], but MyApp, etc. If not sure, you can determine the exact lookup string by looking in SystemOut.log file of the WebSphere 8.5.5 server for the message CNTR0167I. For example, the actual message would look like this:

CNTR0167I: The server is binding the javax.management.j2ee.ManagementHome interface of the Management enterprise bean in the mejb.jar module of the ManagementEJB application.  The binding location is: java:global/ManagementEJB/mejb/Management!javax.management.j2ee.ManagementHome
