    jboss & NoInitialContextException

    mrf Newbie

      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)

                ... 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
