This is a problem I faced, too. I see two possible solutions.
i. use JavaScript in login.jsp so that onLoad event will ensure that it
is on top and not inside a frame.
ii. direct to a page saying <a href="login.jsp"
target="_top">relogin</a> and that should do even if the relogin page
comes inside the frame the login will come on top.
I think ii. is simple and I have done this as it does not require
JavaScript to be enabled in the client browser.
