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 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

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")); 

    } 
}

My Server side EJB:

Greeter.java

package org.myapp.ejb;

    /**

    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); 

}
