WildFly, OpenEJB and simple ejb application

[Sergei Zhylinski]

Hi Everyone,

Could someone please help to cope with JNDI naming in WildFly? I have deployed a simple stateless session bean into WildFly AS. The output of the server is as follows:

java:global/firstejb/EmployeeServiceBean!com.sze.ejb.EmployeeService
java:app/firstejb/EmployeeServiceBean!com.sze.ejb.EmployeeService
java:module/EmployeeServiceBean!com.sze.ejb.EmployeeService
java:jboss/exported/firstejb/EmployeeServiceBean!com.sze.ejb.EmployeeService
java:global/firstejb/EmployeeServiceBean
java:app/firstejb/EmployeeServiceBean
java:module/EmployeeServiceBean

My bean is a simple transaction scoped stateless session bean with container-managed transaction demarcation:

package com.sze.ejb;

import javax.ejb.Remote;
import javax.ejb.Stateless;
import javax.ejb.TransactionManagement;
import javax.ejb.TransactionManagementType;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import javax.persistence.Query;

@Stateless
@Remote(EmployeeService.class)
@TransactionManagement(TransactionManagementType.CONTAINER) // default
@TransactionAttribute(TransactionAttributeType.REQUIRED) // default
public class EmployeeServiceBean implements EmployeeService {

	@PersistenceContext(unitName = "TestJPAService")
	private EntityManager em;
	
	@Override
	public void deductEmployeeVacation(String firstName, String lastName, int days) {
		Query query = em.createQuery("select e from Employee e where e.firstName = :firstName and e.lastName = :lastName");
		query.setParameter("firstName", firstName).setParameter("lastName", lastName);
		Employee employee = (Employee) query.getSingleResult();
		int vacationDays = employee.getVacationDays();
		employee.setVacationDays(vacationDays - days);
	}
}

It has a remote view, so the clients are able to get a reference to it from a separate JVM. My remote client has the following code:

package  com.sze.ejb.client;

import java.util.Properties;

import javax.naming.Context;
import javax.naming.InitialContext;

import com.sze.ejb.EmployeeService;

public class RemoteEJBClient {
	
	public static void main(String[] Args) {
		try {
			Properties jndiProps = new Properties();
			jndiProps.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");
			jndiProps.put(Context.PROVIDER_URL, "http-remoting://localhost:8080");
			// username
			jndiProps.put(Context.SECURITY_PRINCIPAL, "zhise");
			// password
			jndiProps.put(Context.SECURITY_CREDENTIALS, "qwe123");
			Context ctx = new InitialContext(jndiProps);
			EmployeeService employeeService = (EmployeeService) ctx.lookup("java:global/firstejb/EmployeeServiceBean!com.sze.ejb.EmployeeService");
			employeeService.deductEmployeeVacation("Sergei", "Zhylinski", 12);
		} catch(Exception e) {
			e.printStackTrace();
		}
	}
}

This code works fine with OpenEJB when I specify an OpenEJB context factory. But in WildFly I am always getting the following error:

javax.naming.NameNotFoundException: global/firstejb/EmployeeServiceBean!com.sze.ejb.EmployeeService -- service jboss.naming.context.java.jboss.exported.global.firstejb."EmployeeServiceBean!com.sze.ejb.EmployeeService"

Thanks for everyone, who has read the topic and is willing to help. I managed to cope with this by myself. I should have read this article first. I have also found the topic on CodeRanch about this issue. So my remote client should look as follows:

package  com.sze.ejb.client;

import java.util.Properties;

import javax.naming.Context;
import javax.naming.InitialContext;

import com.sze.oceejbd.EmployeeService;

public class RemoteEJBClient {
	
	public static void main(String[] Args) {
		try {
			Properties jndiProps = new Properties();
			jndiProps.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");
			jndiProps.put(Context.PROVIDER_URL, "http-remoting://localhost:8080");
			// username
			jndiProps.put(Context.SECURITY_PRINCIPAL, "zhise");
			// password
			jndiProps.put(Context.SECURITY_CREDENTIALS, "qwe123");
			jndiProps.put("jboss.naming.client.ejb.context", true);
			Context ctx = new InitialContext(jndiProps);
			EmployeeService employeeService = (EmployeeService) ctx.lookup("firstejb/EmployeeServiceBean!com.sze.ejb.EmployeeService");
			employeeService.deductEmployeeVacation("Sergei", "Zhylinski", 12);
		} catch(Exception e) {
			e.printStackTrace();
		}
	}
}

Thanks again.

java:global/firstejb/EmployeeServiceBean!com.sze.ejb.EmployeeService

Try

ctx.lookup("firstejb/EmployeeServiceBean!com.sze.ejb.EmployeeService");

I had a similar problem before and found that I needed to prefix the JNDI name with ejb:(instead of java:).

This is a working example that I had - similar to what you are trying:

import java.util.List;
import java.util.Properties;
 
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
 
import net.starsolutions.entities.EquipmentBundle;
import net.starsolutions.inventorymanager.InventoryManager;
 
public class Main {
    public static void main(String[] args) throws NamingException {
        new Main();
    }
 
    public Main() throws NamingException {
 
        Properties env = new Properties();
        env.put(Context.INITIAL_CONTEXT_FACTORY,
                "org.jboss.naming.remote.client.InitialContextFactory");
        env.put(Context.PROVIDER_URL, "http-remoting://localhost:8080");
        env.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
        env.put("jboss.naming.client.ejb.context", true);
        InitialContext context = new InitialContext(env);
 
        String ejbJndiName = "ejb:InventoryManagement/InventoryManager//"
                + "InventoryManagerImpl!net.starsolutions.inventorymanager.InventoryManagerRemote";
        InventoryManager inventoryManager = (InventoryManager) context
                .lookup(ejbJndiName);
 
        List<EquipmentBundle> bundles = inventoryManager.getEquipmentBundles();
 
        context.close();
    }
 
}
