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.

You're mixing up JTextField and JTextArea, use JTextArea.append()

;JOOP!

gnoonConnect With a Mentor Commented:
The search variable is JTextField and JTextField class *didn't have* append method (append is a method of JTextArea class) http://java.sun.com/j2se/1.4.2/docs/api/javax/swing/JTextField.html.
However, you can use    search.setText( search.getText() + "\n" );  instead.
