So far im trying to make this EJB to work with no succes til now. I really dont know what is the problem. I'm following this book and I tried the examples and all works fine in a local server, but now, i deployed my beans to an external server, with a public IP, and I cant seem to get things work. The Bean is this: package server.ejb.gmail;   import javax.ejb.Stateless; import com.google.gdata.data.appsforyourdomain.AppsForYourDomainException; import com.google.gdata.client.appsforyourdomain.*; import sample.appsforyourdomain.*;   @Stateless public class GmailBean implements GmailBeanRemote, GmailBeanLocal {         public void ConexionGmail()     {                 AppsForYourDomainClient client = null;         try {             client = new AppsForYourDomainClient("user(a)domain.com",                     "password", "domain.com");                         System.out.println("Hello world");         } catch (Exception e) {               System.out.println("Error conexion gmail:" + e.getMessage());           }     }   } GmailBeanRemote looks like this: package server.ejb.gmail; import javax.ejb.Remote;   @Remote public interface GmailBeanRemote {      public void ConexionGmail(); } GmailBeanLocal is exactly like the remote counterpart, the only difference is the tag which uses @Local instead of @Remote The client Im using is this: package client.usuario;   import java.util.Properties;   import javax.naming.Context; import javax.naming.InitialContext; import javax.naming.NamingException; import javax.rmi.PortableRemoteObject;   import server.ejb.gmail.GmailBeanRemote; import server.ejb.usuario.UsuarioBeanRemote;   public class CrearUsuario {      public static void main(String[] args) {         try {             Properties p = new Properties();             p.put(Context.INITIAL_CONTEXT_FACTORY,                     "org.jnp.interfaces.NamingContextFactory");                         p.put(Context.URL_PKG_PREFIXES,                     "org.jboss.naming:org.jnp.interfaces");                         p.put(Context.PROVIDER_URL, "jnp://myhost:1099");                         Context ctx = new InitialContext(p);                         Object ref = ctx.lookup("GmailBean/remote");             GmailBeanRemote ebr = (GmailBeanRemote) PortableRemoteObject.narrow(ref, GmailBeanRemote.class);             ebr.ConexionGmail();         } catch (NamingException e)         {             e.printStackTrace();         }     }   } If there is any way the JNDI output is useful, here it is: +- UserTransactionSessionFactory (proxy: $Proxy112 implements interface org.jboss.tm.usertx.interfaces.UserTransactionSessionFactory)   +- UUIDKeyGeneratorFactory (class: org.jboss.ejb.plugins.keygenerator.uuid.UUIDKeyGeneratorFactory)   +- HiLoKeyGeneratorFactory (class: org.jboss.ejb.plugins.keygenerator.hilo.HiLoKeyGeneratorFactory)   +- SecureDeploymentManager (class: org.jnp.interfaces.NamingContext)   |   +- remote[link -> DeploymentManager] (class: javax.naming.LinkRef)   +- SecureManagementView (class: org.jnp.interfaces.NamingContext)   |   +- remote[link -> ManagementView] (class: javax.naming.LinkRef)   +- DeploymentManager (class: org.jboss.aop.generatedproxies.AOPProxy$4)   +- UsuarioBean (class: org.jnp.interfaces.NamingContext)   |   +- local (class: Proxy for: server.ejb.usuario.UsuarioBeanLocal)   |   +- local-server.ejb.usuario.UsuarioBeanLocal (class: Proxy for: server.ejb.usuario.UsuarioBeanLocal)   |   +- remote-server.ejb.usuario.UsuarioBeanRemote (class: Proxy for: server.ejb.usuario.UsuarioBeanRemote)   |   +- remote (class: Proxy for: server.ejb.usuario.UsuarioBeanRemote)   +- XAConnectionFactory (class: org.hornetq.jms.client.HornetQConnectionFactory)   +- ProfileService (class: org.jboss.aop.generatedproxies.AOPProxy$2)   +- SecureProfileService (class: org.jnp.interfaces.NamingContext)   |   +- remote[link -> ProfileService] (class: javax.naming.LinkRef)   +- queue (class: org.jnp.interfaces.NamingContext)   |   +- DLQ (class: org.hornetq.jms.client.HornetQQueue)   |   +- ExpiryQueue (class: org.hornetq.jms.client.HornetQQueue)   +- UserTransaction (class: org.jboss.tm.usertx.client.ClientUserTransaction)   +- ConnectionFactory (class: org.hornetq.jms.client.HornetQConnectionFactory)   +- jmx (class: org.jnp.interfaces.NamingContext)   |   +- invoker (class: org.jnp.interfaces.NamingContext)   |   |   +- RMIAdaptor (class: javax.management.MBeanServerConnection)   |   +- rmi (class: org.jnp.interfaces.NamingContext)   |   |   +- RMIAdaptor (class: javax.management.MBeanServerConnection)   +- ProxyFactory (class: org.jnp.interfaces.NamingContext)   |   +- UsuarioUnico (class: org.jnp.interfaces.NamingContext)   |   |   +- UsuarioBean (class: org.jnp.interfaces.NamingContext)   |   |   |   +- UsuarioBean (class: org.jnp.interfaces.NamingContext)   |   |   |   |   +- remote (proxy: $Proxy197 implements interface org.jboss.ejb3.proxy.impl.factory.session.SessionSpecProxyFactory,interface org.jboss.ejb3.proxy.impl.factory.session.SessionProxyFactory,interface org.jboss.ejb3.proxy.impl.factory.ProxyFactory)   |   |   +- GmailBean (class: org.jnp.interfaces.NamingContext)   |   |   |   +- GmailBean (class: org.jnp.interfaces.NamingContext)   |   |   |   |   +- remote (proxy: $Proxy197 implements interface org.jboss.ejb3.proxy.impl.factory.session.SessionSpecProxyFactory,interface org.jboss.ejb3.proxy.impl.factory.session.SessionProxyFactory,interface org.jboss.ejb3.proxy.impl.factory.ProxyFactory)   +- BeanValidatorFactories (class: org.jnp.interfaces.NamingContext)   +- persistence.unit:unitName=#timerdb (class: org.hibernate.impl.SessionFactoryImpl)   +- TomcatAuthenticators (class: java.util.Properties)   +- GmailBean (class: org.jnp.interfaces.NamingContext)   |   +- local (class: Proxy for: server.ejb.gmail.GmailBeanLocal)   |   +- remote (class: Proxy for: server.ejb.gmail.GmailBeanRemote)   |   +- local-server.ejb.gmail.GmailBeanLocal (class: Proxy for: server.ejb.gmail.GmailBeanLocal)   |   +- remote-server.ejb.gmail.GmailBeanRemote (class: Proxy for: server.ejb.gmail.GmailBeanRemote)   +- XAThroughputConnectionFactory (class: org.hornetq.jms.client.HornetQConnectionFactory)   +- ManagementView (class: org.jboss.aop.generatedproxies.AOPProxy$3)   +- ThroughputConnectionFactory (class: org.hornetq.jms.client.HornetQConnectionFactory) I dont know what to do to make it work, so any help would be really appreciated.
