Examples of javax.naming.NameClassPair

javax.naming.NameClassPair
NameClassPair associates a name in a naming service with a specified class name and also with a relative flag. In JNDI, NameClassPair is extended by javax.naming.Binding; Binding objects are used in javax.naming.Context implementations.
A NameClassPair object is not thread-safe unless appropriate synchronization is applied to any code manipulating these objects.

As this class implements the Serializable interface, it is important that fields below are declared with the same names.

    System.out.println("JNDI props = " + props + "\n");
    
    javax.naming.Context jndiCtx = new javax.naming.InitialContext(props);
     NamingEnumeration e = jndiCtx.list("");
     while (e.hasMore()) {
       NameClassPair ncp = (NameClassPair) e.next();
       System.out.println("ncp = " +ncp);
       System.out.println("  obj = " + jndiCtx.lookup(ncp.getName()));
     }
     jndiCtx.close();


    System.out.println("Admin closed.");
