Hi,
Yes, I mean Java Web Start Swing/SwingX application. My idea is from the
beginning the authorization to be not required. The authorization to be
required when the user is accessing some EJB which requires some role.
Something like HTTP where you can browse the pages and when you click to
page which require authorization the authorization page is shown.
Your try and experience are very useful. Can you send me some code or
zipped NetBeans project for test? I am using NetBeans 6 M9 and GlassFish
v2-b45.
From where you read how to do that? I mean not only the Java classes, I
mean the configuration and installation instructions like XML and
properties modifications.
Regards,
Miro.
