About InitialContext in distributed environment

[Ailsa Cape]

Hello everyone,

When I test my first EJB application using a remote client, a runtime exception occurs,

Caught an exception!
javax.naming.CommunicationException: Can't find SerialContextProvider

After I read some posts here which are relative to this subject, I add three new lines in my client code:

Hashtable map = new Hashtable();
map.put(InitialContext.INITIAL_CONTEXT_FACTORY,
        "org.jnp.interfaces.NamingContextFactory");
map.put(InitialContext.PROVIDER_URL, "jnp://100.252.201.205.:1050");
 
Context ictx = new InitialContext(map);

I don't quite catch these code and I still got another runtime exception after doing so,

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

I want to know what is the correct environment for a client accessing an Enterprise bean on a remote server running Sun's Reference Implementation? I use J2SE 1.3.1 &J2EE 1.3.1

Thanks in advance!
