EJB stateless issue EJBCLIENT000025: No EJB receiver available for handling

[necrolax]

Hi,

I am trying to create an EJB stateless session bean in Wildfly 8.2. I need to create the stateless session without annotations and need where to configure appropriate properties in xml. I am getting the following error when i try to lookup the stateless bean

Could anyone please suggest when we will get this error ??

Any working sample code ??

Did you had look to the wildfly quickstarts Quickstarts ?

From the name I suppose MyFirstWildFlySessionBean is the bean name and not the name of the JAR. How your deployment look like? Did you use an ear or a simple jar and how you create the client?

Maybe the quickstart help here.

The XNIO000812 might network related, how your environment look like?

How are you doing the EJB lookup?

The reason for the EJBCLIENT000025 message might be that the property jboss.naming.client.ejb.context is not set to true.

Hi all,

Please find the attached files. I have used the RemoteCalculator stateless session bean example from WildFly online doc.

Thanks

You try to mix the ejb-client and the remote-naming approach.

Ty to remove "jboss.naming.client.ejb.context" from your InitialContext

[mayerw01]

Is your port number really 4447? Usually this is 8080.

This works in my environment. Maybe you can try this approach:

public class TestRemoteClient {

    public static void main(String[] args) {

        if (args.length < 2)

        {

            System.err.println ("2 integer values expected");

            System.exit(99);

         }

        int val1 = parseInt(args [0]);

        int val2 = parseInt(args [1]);

        Properties props = new Properties();

        final String bean = "TestRemoteJNDI/TestRemoteJNDI-ejb/CalculateBean!ejb.CalculateBeanRemote";

        CalculateBeanRemote cal;

        System.out.println("Testing with: " + bean);

        props.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");

        props.put(Context.PROVIDER_URL, "http-remoting://localhost:8080");

        props.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");

        props.put(Context.SECURITY_PRINCIPAL, "guest");

        props.put(Context.SECURITY_CREDENTIALS, "guest");

        // to avoid: java.lang.IllegalStateException: EJBCLIENT000025: No EJB receiver available

        props.put("jboss.naming.client.ejb.context", true);

        try {

            final Context context = new InitialContext(props);

            cal = (CalculateBeanRemote) context

                    .lookup(bean);

            System.out.println("Lookup complete");

            System.out.println(val1 + " + " + val2 + " = " + cal.add(val1, val2));

            // context.close();   // throws: java.util.concurrent.RejectedExecutionException

        } catch (NamingException e) {

            e.printStackTrace();

        }

    }

}
