I am a new user of jboss. I tried deploying a sample EJB apllication by following the tutorial at :- http://www.huihoo.org/jboss/online_manual/2.4/ch01s15.html . I was able to deploy the application in jboss <4.2.2GA> . but on calling EJB via a simple client, I face the following exception :- 
     [java] hi
     [java] Exception in thread "main" java.lang.NoClassDefFoundError: org/jboss
     [java]     at org.jnp.interfaces.NamingContext.(NamingContext.java:

     [java]     at org.jboss.docs.interest.InterestClient.main(InterestClient.ja
     [java] Java Result: 1

I tried googling and my classpath has jbossall-client.jar in it. However still facing this problem.

The client code is :- 
package org.jboss.docs.interest;

import javax.naming.InitialContext;
import javax.rmi.PortableRemoteObject;

import org.jboss.docs.interest.Interest;
import org.jboss.docs.interest.InterestHome;

/** This simple application tests the 'Interest' Enterprise JavaBean which is
 implemented in the package 'org.jboss.docs.interest'. For this to work, the
 Bean must be deployed on an EJB server.
class InterestClient
   /** This method does all the work. It creates an instance of the Interest EJB on
    the EJB server, and calls its `calculateCompoundInterest()' method, then prints
    the result of the calculation.
   public static void main(String[] args)

      // Enclosing the whole process in a single `try' block is not an ideal way
      // to do exception handling, but I don't want to clutter the program up
      // with catch blocks
      InitialContext jndiContext=null;
         // Get a naming context
         jndiContext = new InitialContext();
         System.out.println("Got context");

      catch(Exception e)
    		System.out.println("I am here!!");


    // Get a reference to the Interest Bean
         Object ref  = jndiContext.lookup("interest/Interest");
         System.out.println("Got reference");

         // Get a reference from this to the Bean's Home interface
         InterestHome home = (InterestHome)
         PortableRemoteObject.narrow(ref, InterestHome.class);

         // Create an Interest object from the Home interface
         Interest interest = home.create();

         // call the calculateCompoundInterest() method to do the calculation
         System.out.println("Interest on 1000 units, at 10% per period, compounded over 2 periods is:");
         System.out.println(interest.calculateCompoundInterest(1000, 0.10, 2));
      catch(Exception e)

Please guide in this ...Any help would be apprecitated. Thanks in advance.
