Molti componenti swing supportano HTML.
Prova ad inserire il codice, usando i tag appropriati...
Tipo: <HTML>
testo</HTML>
Mmmmh...no non credo che funzionerebbe con una semplice textarea,devci usare il textcomponent per l'html incluso nella libreria java,con quello riesci di sicuro.
Qusto codice credo ti possa essere utile,ciao.
codice:
import javax.swing.*;
import javax.swing.event.*;
import javax.swing.text.Document;
import java.net.URL;
import java.io.*;
import java.awt.Cursor;
