Que tal LEYER. Gracias por la ayuda y la paciencia-
Le he puesto entre las comillas texto, solo que en lo que postee anteriormente puse
listModel.addElement("");
por descuido.
Ya he metido el jList y el DefaultListModel en el jFrame, pero no resulta nada.
El codigo que esta en mi desktopapplication es este:

Es mucho código que se genera automáticamente.
Yo creo que algo anda mal, porque si meto otro jList (sería jList2), como indico a que jList meter el string. si al jList1 o al jList2. (sólo en caso de que tenga dos jList)
La verdad ya me comenzé a desesperar porque por mas que veo ejemplos no logro entender eso de DefaultListModel y todo eso.
Espero la ayuda de alguien.
Un saludo!

es decir listModel.addElement("Elemento"); al jlist se le agregara "elemento"
ademas no uso netbeans por el cual me generaria errores en el code.
