OK - I must admit I did not look carefully at
the code that you put initially, not that it
compiles. I can make it work quite easily.

Try this SSCCE*. (And while I am on the subject,
please also consider posting SSCCE code in future.

<sscce>
// package names should be alllowercase according to the
// usual nomenclature.
//package ALIIS;
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

import javax.swing.JFrame;

public class InputListener extends JFrame
{

  public static void main (String [] args)
  {
    new InputListener();
  }

  public InputListener ()
  {
    this.setSize(300,300);
    this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    this.setTitle("ALiiS");

    JPanel panel1 = new JPanel();
    Clisten atl = new Clisten();
    TextField t = new TextField();
    t.setSize(300, 300);
    t.addTextListener(atl);

    add ( t ) ;
    this.add(panel1);
    this.setVisible (true);
  }

  public class Clisten implements TextListener
  {

    public void textValueChanged ( TextEvent e )
    {
      System.out.println(e);
      TextComponent tc = (TextComponent)e.getSource();
      // attributes should be camelCase
      String inputrules = tc.getText();
      System.out.println("'" + inputrules + "'");
      if (inputrules.equals("")) {
        return;
      }
      if (inputrules.equals("Chris"))
      {
        tc.setText("");
      //Here I need to somehow refresh the textfield
      }
      else
      {
        // Here as well...

        // Why here? If this clears the text field,
        // it would be impossible to type 'Chris',
        // as the field would be cleared for 'C'!
      }
    }
  }
}
</sscce>

But like Knute, I am really not sure what it
is you are trying to achieve here.
