EJB lookup fails during startup but is fine when the call is made after the server is started.

Latest response

HI All

I am using Jboss EAP 7.1. And i managed to deploy a stateless EJBbean successfully.

And i am also able to access the deploy EJB after the server is started successfully. using the below piece of code.

final Hashtable jndiProperties = new Hashtable();
    jndiProperties.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");
    jndiProperties.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
    jndiProperties.put("jboss.naming.client.ejb.context", true);
    Context context;
    try {
        context = new InitialContext(jndiProperties);
        String appName = "";

        if ("FlowControllerBean/remote".equalsIgnoreCase(jndiName)) {
            appName = "";

        } else {
            appName = "upm-0.1";
        final String distinctName = "";
        String beanName = "";
        final String viewClassName = FlowController.class.getName();
                "ejb:" + appName + "/" + moduleName + "/" + distinctName + "/" + beanName + "!" + viewClassName);
        if ("".equalsIgnoreCase(interfacename)) {
            context = new InitialContext();
            return context.lookup(jndiName);
        } else {
            beanName = jndiName.substring(0, jndiName.indexOf("/"));
            return context.lookup("ejb:" + appName + "/" + moduleName + "/" + distinctName + "/" + beanName + "!"
                    + interfacename);
    } catch (NamingException e) {
        // TODO Auto-generated catch block
    return null;

But my real problem comes when i want to access the same EJB during server start up itself. One of my method inside a service bean calls this EJB Bean during server startup itself. But it fails with the message "EJBCLIENT000079: Unable to discover destination for request for EJB StatelessEJBLocator for "/ejb-remote-server/FlowControllerBean", view is interface com.hexaware.framework.flowcontroller.FlowController, affinity is None".

Before the lookup is executed the actual EJB beans are deployed. Please find below the logs from server before the lookup is made during start up.

14:36:25,971 INFO [org.jboss.weld.deployer] (MSC service thread 1-4) WFLYWELD0003: Processing weld deployment ejb-remote-server.jar

But the same code works if i call it after the server is started completely.

Please help.
Below is how i have defined my EJBbean.

@Stateless(mappedName = "FlowController/remote")
public class FlowControllerBean implements FlowController
public TransferObject execute(TransferObject transferObject) throws ApplicationException {

Below is my property file which i have used for connecting from the client to my remote server.Both server and client are in same Jboss server instance in my local machine.

remote.connection.default.port = 8080

Note: Look up is successful during startup or any other time. But when i try to call a method in the bean the error message is encountered. But same bean method call works after server startup

You cannot remotely invoke an EJB on a server that is not up and running. The ejb: lookup does not actually make a remote call, so it will return a proxy without connecting to the remote machine.
