Your post contains a link to the API documentation for JTable (and so does this reply now). That documentation contains a link to Sun's tutorial about JTable. Follow that link and read the tutorial. Experiment with JTable and its related classes.
Once you have done that you should realize that the fact that your objects happen to be created via JAXB is irrelevant as far as the JTable is concerned.
Or have you already done that, and you have a specific problem which only arises with objects created via JAXB? If so, it would help if you told us what it was.
