public InitialLdapContext() throws NamingException 
{
        super(null);
}

Constructs an initial context using no environment properties or connection request controls. Equivalent to new InitialLdapContext(null, null).

Throws:

NamingException - if a naming exception is encountered

 public InitialLdapContext(Hashtable<?, ?> environment,
    Control[] connCtls) throws NamingException 
{
        super(true); // don't initialize yet
        // Clone environment since caller owns it.
        Hashtable env = (environment == null)
            ? new Hashtable(11)
            : (Hashtable)environment.clone();
        // Put connect controls into environment.  Copy them first since
        // caller owns the array.
        if (connCtls != null) {
            Control[] copy = new Control[connCtls.length];
            System.arraycopy(connCtls, 0, copy, 0, connCtls.length);
            env.put(BIND_CONTROLS_PROPERTY, copy);
        }
        // set version to LDAPv3
        env.put("java.naming.ldap.version", "3");
        // Initialize with updated environment
        init(env);
}

Constructs an initial context using environment properties and connection request controls. See javax.naming.InitialContext for a discussion of environment properties.

This constructor will not modify its parameters or save references to them, but may save a clone or copy. Caller should not modify mutable keys and values in environment after it has been passed to the constructor.

connCtls is used as the underlying context instance's connection request controls. See the class description for details.

Parameters:

environment - environment used to create the initial DirContext. Null indicates an empty environment.

connCtls - connection request controls for the initial context. If null, no connection request controls are used.

Throws:

NamingException - if a naming exception is encountered
