    Cannot instantiate class: org.jnp.interfaces.NamingContextFa

    xlahaut Newbie

      Help !!!!!!!
      I'm trying to instanciate a session bean in a client
      Applet. All the necessary jar are attached to the applet, and I'm initializing the Context with all the necessary parameters... but I still have the Exception :

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

      at applet.FileManager.getDownloadFile(FileManager.java:80)

      Here is the code of the applet:

      Properties jndiProps = new Properties();
      jndiProps.setProperty("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory" ) ;
      jndiProps.setProperty("java.naming.provider.url", "localhost" ) ;
      jndiProps.setProperty("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces" ) ;
      Context ctx = new InitialContext(jndiProps);
      Object objref = ctx.lookup("ejb/session/LetterSession");
      LetterSessionHome letterSessionHome = (LetterSessionHome)javax.rmi.PortableRemoteObject.narrow(objref, LetterSessionHome.class);
      theLetterSession = letterSessionHome.create();

      and here is the declaration of the applet in the jsp :
      <!--"CONVERTED_APPLET"-->
      <!-- CONVERTER VERSION 1.0 -->




      <param name = ARCHIVE VALUE = "letter-template.jar, jboss-common-client.jar, jboss-client.jar, jboss-j2ee.jar, jbosssx-client.jar, jnp-client.jar, jndi.jar, jaas.jar, log4j.jar">
      <param name = "clientLocalDirectory" value = '<%= session.getAttribute("clientLocalDirectory") %>'

      <!--"END_CONVERTED_APPLET"-->

      Is the order of the declaration of the jar is signifiant ?
      I tried to instanciate explicitly a NamingContextFactory in my applet, and it works !!! So why have I this ClassNotFounException on the new InitialContext ?????????????????
      I need help !!!!!
