Hi everybody,

I'm new in the world of the EJB so to understand it I try to make the
HelloWorld tutorial that I found there:
http://users.pandora.be/bert.torfs/j2ee.pdf

I have deployed the HelloServer without problems. But when I try to
execute the HelloClient I have an exception:

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

    ... 5 more
Exception in thread "main"

Can someone help me and tell me what to do to make it run? :(
