Lines of text on JEditorPane

I need to open an ASCII text file, read the lines (one by one) and add then to a JEditorPane. I cannot use the reader like this:

FileReader reader =new FileReader(dataFile);

dataDisplay.read(reader,null);

because I have to do some manipulation with the lines first. Anyway, the point is that I have no idea how to add the lines one by one. I tried this:

while (line !=null ){

line = in.readLine();

dataDisplay.setText(line);//dataDisplay is my JEditorPane

}

but I end up with just the last line of the file in display. Any suggestions?

Thanks!
