Hi,

I recently started learning EJB. I was trying to follow the work book examples from the EJB 3.0 book by Bill Burke & Richard Monson-Haefel. I have an eclipse, and JBoss 7 Final configured. I was able to deploy my first stateless bean and an entity to the server, but I am not able to run the client. The exception I get is:

javax.naming.NoInitialContextException: Cannot instantiate class: org.jnp.interfaces.NamingContextFactory [Root exception is java.lang.ClassNotFoundException: org.jnp.interfaces.NamingContextFactory]

          at javax.naming.spi.NamingManager.getInitialContext(Unknown Source)

          at javax.naming.InitialContext.getDefaultInitCtx(Unknown Source)

          at javax.naming.InitialContext.init(Unknown Source)

          at javax.naming.InitialContext.<init>(Unknown Source)

          at com.titan.clients.Client.getInitialContext(Client.java:37)

          at com.titan.clients.Client.main(Client.java:11)

          at java.lang.Class.forName(Unknown Source)

          at com.sun.naming.internal.VersionHelper12.loadClass(Unknown Source)

          ... 6 more

The client code:

package com.titan.clients;

import javax.naming.Context;

import com.titan.domain.Cabin;

import com.titan.travelagent.TravelAgentBeanRemote;

public class Client {

          public static void main(String[] args) {

                    try {

                              Context jndiContext = getInitialContext();

                              Object ref = jndiContext.lookup("TravelAgentBean/remote");

                              TravelAgentBeanRemote dao = (TravelAgentBeanRemote) 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 {

                    return new javax.naming.InitialContext();

          }

}

The jndi.properties file:

java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory

java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces

java.naming.provider.url=localhost

I also tried setting the properties by injecting the constructor: new InitialContext(properties);

Sadly, to no avail...

The persistence.xml:

<?xml version="1.0" encoding="UTF-8"?>

<persistence version="2.0"

          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_2_0.xsd">

          <persistence-unit name="titan">

                    <jta-data-source>java:jboss/datasources/ExampleDS</jta-data-source>

                    <properties>

                              <property name="hibernate.hbm2ddl.auto" value="create-drop" />

                    </properties>

          </persistence-unit>

</persistence>

I'll be happy to post any more files/contents, am just not sure what else can be helpful or is needed.

There are tones of similar issues on the internet, but I wasn't able to fix my issue.

Can anyone help me to sort it out?

Thanks
