Orion primer

[Eric Wong]

I followed the orion primer and got the example to work.  What I don't understand is 
the following code in the servlet:

// Get the initial JNDI context
Context context = new InitialContext();
// Get a reference to the Hello interface
Object boundObject = context.lookup(helloHomeLocation);
HelloHome helloHome = (HelloHome) PortableRemoteObject.narrow(boundObject, 
HelloHome.class);


How is the initial context acquire without all passing in a Hashtable or Properties 
object?  

thanks,
eric
