      I tried to do a remote EJB lookup from a standalone client, but got the following exception on my client application:

       

      Exception in thread "main" java.lang.NoSuchMethodError: org.jboss.logging.Logger.getMessageLogger(Ljava/lang/Class;Ljava/lang/String;)Ljava/lang/Object; 
    at org.jboss.ejb.client.Logs.<clinit>(Logs.java:44) 
    at org.jboss.ejb.client.EJBClient.<clinit>(EJBClient.java:39) 
    at org.jboss.ejb.client.naming.ejb.EjbNamingContext.doCreateProxy(EjbNamingContext.java:139) 
    at org.jboss.ejb.client.naming.ejb.EjbNamingContext.createEjbProxy(EjbNamingContext.java:113) 
    at org.jboss.ejb.client.naming.ejb.EjbNamingContext.lookup(EjbNamingContext.java:96) 
    at javax.naming.InitialContext.lookup(InitialContext.java:392) 
    at EjbClient.main(EjbClient.java:30)

      I followed this guide to creating the client:

       

      https://docs.jboss.org/author/display/AS71/EJB+invocations+from+a+remote+client+using+JNDI

       

      My environment:

       

      Server: JBoss AS 7.1.0.Final

      Client VM: JavaSE 1.6 Mac OS X VM

       

      Client libraries:

      jboss-transaction-api_1.1_spec-1.0.0.Final.jar

      jboss-ejb-api_3.1_spec-1.0.1.Final.jar

      jboss-ejb-client-1.0.2.Final.jar

      jboss-marshalling-1.3.9.GA.jar"/>

      jboss-sasl-1.0.0.Final.jar"/>

      jboss-marshalling-river-1.3.9.GA.jar

      jboss-logging-3.1.0.GA.jar

      xnio-nio-3.0.3.GA.jar

      jboss-remoting-3.2.2.GA.jar

      xnio-api-3.0.3.GA.jar

       

      My client side code:

       

      import java.util.Hashtable; 

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

import org.myapp.ejb.Greeter; 
import org.myapp.ejb.GreeterRemote; 


public class EjbClient { 
    public static void main(String[] args) throws NamingException{ 

        final Hashtable jndiProperties = new Hashtable(); 
        jndiProperties.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming"); 
        Context context = new InitialContext(jndiProperties); 

        String beanName = Greeter.class.getSimpleName(); 
        String viewClassName = GreeterRemote.class.getName(); 

        GreeterRemote greeter = (GreeterRemote) context.lookup("ejb:" + "myejb/" + beanName + "/"   + "!" + viewClassName); 

        System.out.println(greeter.greet("Jason")); 

    } 
}

      jboss-ejb-client.properties

       

      remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED=false 

remote.connections=default 

remote.connection.default.host=localhost 
remote.connection.default.port = 4447 
remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS=false 


remote.connection.default.username=appuser 
remote.connection.default.password=apppassword

       

      My Server side EJB:

       

      Greeter.java

       

      package org.myapp.ejb; 

import javax.ejb.Stateless; 

/** 
 * Session Bean implementation class Greeter 
 */ 
@Stateless 
public class Greeter implements GreeterRemote { 

    /** 
     * Default constructor. 
     */ 
    public Greeter() { 
        // TODO Auto-generated constructor stub 
    } 

    @Override 
    public String greet(String user){ 
        return "Hello " + user; 
    } 
}

      GreeterRemote.java

       

      package org.myapp.ejb; 
import javax.ejb.Remote; 

@Remote 
public interface GreeterRemote { 

    String greet(String user); 

}
