Hi,

I'm beginner in java programming web application.
I found, how to use JDBCRealm, it works fine, but can you tell (show some example, plese:-) I can't find anything) me, how can I add link to logout on JSP page? And how can I get username for login user?

EDIT? I would want show info for login user, for example: "Login as ..... and you can logout here"...

Thanks
