How to display a warning message.
hi,
I try to display a message in a jsp page. Is correct to use a
JOptionPane? There are other options to show a message from the Action
class ?
1 The user fill a form.
2 an action look in the database
3 if i have a empty result i show a warning message.
/* check the list */
final ModelForm form = (ModelForm) ctx.form();
if (form.getModelNameList().isEmpty())
{
form.showMessage("please select another brand");
form.setErrorMsg ("pleases select another brand");
clearModel_onClick(ctx);
return false;
}
/* in form class */
public void showMessage (
String message)
{
JOptionPane messageBox = new JOptionPane ();
JOptionPane.showMessageDialog (messageBox, message, "Warning",
JOptionPane.WARNING_MESSAGE);
messageBox.setVisible (true);
}
The problem if I use a JOptionPane the first time i used it will be
under the browser.
Thanks.
PS: If this is not the correct mail list please let me know.

I think you can use a javascript 'alert' funcion.
Anyway, in my humble opinion, I think it's better to read the j2ee
tutorial first on java.sun.com ...
