[Swing]Créer un mini editeur de text (JEditorPane )en enregistrer en HTML

Salut,

Je suis en train d'ecrire un pogramme qui permettra de saisir du texte dans un JEditorPane. L'utilisateur pourra sélectionner une partie du texte et en cliquant sur le boutton: bold, le mettre en gras ect... Voici une version simplifiée du code qui marche. Il charge dans le JEditorPane un page HTML en guise d'exemple.

<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">

<body>
<p>Simple text</p>
<p><strong>Bold text</strong></p>
<p><em>Italic text</em></p>

<p>&nbsp;</p>
</body>
</html>

Egalement je voudrais qu'en cliquant sur le bouton Save on enregistre et exporte le contenu du JEditorPane en HTML. Actuellement il change seulement le texte selectionné.

Toute suggestions ou bouts de code pouvant m'aider serait grandement apprecié.

Merci.
