method not found error

Hi, i have a java file that contacts an rmi server and makes google based querys through that server. When I search the web (the server uses google) using the java gui I want each website address to be seperated by a new line but im getting this error:

--------------------Configuration: j2sdk1.4.0_02 <Default>--------------------
C:\ronaynea\Client.java:255: cannot resolve symbol
symbol : method append (java.lang.String)
location: class javax.swing.JTextField
           search.append("\n");
^
1 error

Process completed.

when I call this method: search.append("\n");

This is what im importing:
import java.io.*;
import java.rmi.*;
import java.rmi.server.*;
import java.lang.*;
import javax.swing.*;

Some more more below if that helps, the append method is included.

Thanks, any help at all would be brilliant.
