Hjælp til J2EE, EJB3 og jboss-5.0.0.GA

Hej Eksperter,
jeg er lige gået i gang med at lære J2EE, men er desværre løbet ind i problemer med et meget simpelt eksempel:

com.titan.domai:
Cabin.java

package com.titan.domain;
import javax.persistence.Entity;
import javax.persistence.Table;
import javax.persistence.Column;
import javax.persistence.Id;

@Entity
@Table(name="CABIN")
public class Cabin implements java.io.Serializable
{
    private int id;
    private String name;
    private int deckLevel;
    private int shipId;
    private int bedCount;

    @Id
    @Column(name="ID")
    public int getId()
    {
    return id;
    }
    public void setId(int pk)
    {
    id = pk;
    }

    @Column(name="NAME")
    public String getName()
    {
        return name;
    }
    public void setName(String str)
    {
    name = str;
    }

    @Column(name="DECK_LEVEL")
    public int getDeckLevel()
    {
    return deckLevel;
    }
    public void setDeckLevel(int level)
    {
    deckLevel = level;
    }

    @Column(name="SHIP_ID")
    public int getShipId()
    {
    return shipId;
    }
    public void setShipId(int sid)
    {
    shipId = sid;
    }

    @Column(name="BED_COUNT")
    public int getBedCount()
    {
    return bedCount;
    }
    public void setBedCount(int bed)
    {
    bedCount = bed;
    }
}

-------------------------------

com.titan.travelagent:
TravelAgentRemote.java
TravelAgentBean.java


package com.titan.travelagent;
import javax.ejb.Remote;
import com.titan.domain.Cabin;

@Remote
public interface TravelAgentRemote
{
    public void createCabin(Cabin cabin);
    public Cabin findCabin(int pKey);
}

--------------------------------------------------

package com.titan.travelagent;

import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;

import com.titan.domain.Cabin;

@Stateless
public class TravelAgentBean implements TravelAgentRemote
{
    @PersistenceContext(unitName="titan") private EntityManager manager;
   
    public void createCabin(Cabin cabin)
    {
    manager.persist(cabin);
    }

    public Cabin findCabin(int pKey)
    {
    return manager.find(Cabin.class, pKey);
    }
}


META-INF:
persistence.xml

<?xml version="1.0" encoding="UTF-8"?>
<persistence>
  <persistence-unit name="titan">
      <jta-data-source>java:/DefaultDS</jta-data-source>
      <properties>
        <property name="hibernate.hbm2ddl.auto" value="create-drop"/>
      </properties>
  </persistence-unit>
</persistence>


Dette bliver kompileret til titan.jar som kopiers til:
/jboss-5.0.0.GA/server/default/deploy


Klientkode:

import com.titan.travelagent.TravelAgentRemote;
import com.titan.domain.Cabin;
import javax.naming.InitialContext;
import javax.naming.Context;
import javax.naming.NamingException;
import java.util.Properties;
import javax.rmi.PortableRemoteObject;

public class Client
{
    public static void main(String [] args)
    {
        try
    {
            Context jndiContext = getInitialContext();
            Object ref = jndiContext.lookup("TravelAgentBean/remote");
            TravelAgentRemote dao = (TravelAgentRemote)ref;

            Cabin cabin_1 = new Cabin();
            cabin_1.setId(1);
            cabin_1.setName("Master Suite");
            cabin_1.setDeckLevel(1);
            cabin_1.setShipId(1);
            cabin_1.setBedCount(3);

            dao.createCabin(cabin_1);

            Cabin cabin_2 = dao.findCabin(1);
            System.out.println(cabin_2.getName());
            System.out.println(cabin_2.getDeckLevel());
            System.out.println(cabin_2.getShipId());
            System.out.println(cabin_2.getBedCount());

        }
        catch (javax.naming.NamingException ne)
        {
        ne.printStackTrace();
    }
    }

    public static Context getInitialContext()
        throws javax.naming.NamingException
    {
    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:localhost:1099");
        return new javax.naming.InitialContext(p);
}
}


Jeg benytter ant til at kompiler og eksekver koden:

<?xml version="1.0"?>
<project name="test" default="run" basedir=".">
    <property name="src" value="."/>
    <property name="version" value="1.0"/>
    <property name="build" value="build"/>
    <property name="classes" value="${build}/class"/>   
    <property name="jboss" value="C:/jboss-5.0.0.GA"/>
   
    <path id="classpath">
      <fileset dir="${jboss}/server/default/lib">
        <include name="*.jar"/>
      </fileset>
      <fileset dir="${jboss}/lib">
        <include name="**/*jar*"/>
      </fileset>
      <fileset dir="${jboss}/client">
          <include name="*.jar"/>
      </fileset>
    <fileset dir="../${build}">
      <include name="titan.jar" />
    </fileset>
    <pathelement location="${src}/client-config"/>
    </path>

    <target name="compile">
        <javac srcdir="${src}"
        destdir="${src}"
        debug="on"
        deprecation="on"
        optimize="off"
        includes="**">
        <classpath refid="classpath"/>
      </javac>
    </target>

  <target name="jar" depends="compile">
    <jar destfile="Client.jar" basedir="." includes="**/*.class" />
  </target>

  <target name="run" depends="jar">
    <java classname="Client" classpath="Client.jar" fork="true"/>
    <classpath refid="classpath"/>
  </target>
</project>

Når jeg eksekver programmet får jeg følgende fejl:
javax.naming.NoInitialContextException: Cannot instantiate class: org.jnp.interfaces.NamingContextFactory [Root exception is java.lang.ClassNotFoundException: org.jnp.interfaces.NamingContextFactory]

Jeg kan se at org.jnp.interfaces.NamingContextFactory mangler på runtime, men hvordan får jeg den inkluderet ?!
