h i'm trying to setup a basic exemple ejb project :

my sessionBean :

package ejb3inaction.example;

import javax.ejb.Stateless;

@Stateless
public class HelloUserBean implements HelloUser{

 public void sayHello(String name){
 System.out.println("Hello "+ name + "Welcome t Ejb3!");
 }

}

my HelloUser class:

package ejb3inaction.example;

import javax.ejb.Remote;

@Remote
public interface HelloUser {
 public void sayHello(String name);
}

my persistence.xml file:

<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
 http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd" version="1.0">
 <!--
 <persistence-unit name="chap1PU" transaction-type="JTA">
 <jta-data-source>chap1P</jta-data-source>
 </persistence-unit>
 -->
 <persistence-unit name="chap1PU">
 <jta-data-source>java:/chap1PU</jta-data-source>
 <properties>
 <property name="hibernate.hbm2ddl.auto" value="create-drop" />
 <property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQLDialect"/>
 </properties>
 </persistence-unit>
</persistence>

in jboss-5.0.1.GA/server/default/deploy

i got a chap1PU-ds.xml and his content:

<?xml version="1.0" encoding="UTF-8"?>
<!-- The Hypersonic embedded database JCA connection factory config -->

 <!-- corresponding type-mapping in the standardjbosscmp-jdbc.xml (optional) -->
 <metadata>
 <type-mapping>PostgreSQL 8.2</type-mapping>
 </metadata>
 </local-tx-datasource>
</datasources>

i have copied the jdbc postgresal jar in jboss lib

and i got my test class:

package ejb3inaction.client;



import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.Reader;
import java.util.Properties;

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

import com.ibatis.common.resources.Resources;

import ejb3inaction.example.HelloUser;
import ejb3inaction.example.HelloUserBean;



public class HelloUserClient {
 private static HelloUser helloUser;

 public static void main(String[] args) throws FileNotFoundException, IOException {
 try {
 //Context context = new InitialContext();

 Properties props = new Properties();
 props.setProperty("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");
 props.setProperty("java.naming.provider.url", "jnp://127.0.0.1:1099");
 props.setProperty("java.naming.factory.url.pkgs", "org.jboss.naming");


 Context context = new InitialContext(props);
 //helloUser = (HelloUser) context.lookup("chap1/"+ HelloUserBean.class.getSimpleName() + "/remote");
 String a = "java:/";
 NamingEnumeration ne = context.list(a);
 while (ne.hasMore()) {
 System.out.println("A: " + ne.next().toString());
 }

 //helloUser = (HelloUser) context.lookup("ejb3inaction.client.HelloUser");
 System.out.println("***>"+HelloUserBean.class.getSimpleName());
 //helloUser = (HelloUser) context.lookup(HelloUserBean.class.getSimpleName());
 // helloUser = (HelloUser) context.lookup("ejb3inaction.example."+ HelloUser.class.getSimpleName() + "/remote");
 helloUser = (HelloUser) context.lookup("HelloUserBean/remote");
 helloUser.sayHello("Curious George");
 } catch (NamingException e) {
 e.printStackTrace();
 }
 }
}

when i try to execute it it give me the following error:

and when i try to add all the jars that are in /jboss-5.0.1.GA/client

i got:
