Can a servlet open a new browser window?

[Vanchi Nathan]

Hello all,
Is it possible for a servlet to open a new browser window where an JSP page is displayed?
Your advise please!!!

[Bear Bibeault]

Not directly.
It can, however, return a response containing Javascript that can perform this operation.

[Vanchi Nathan]

Thanks...
In this case, assume the servlet uses an session object; will the same session object be visible in the new browser window?
please advise...

It can either behave in a stateful way and put what ever data you need in the session, or pass the data using hidden form fields or by programatically adding the data to the request.

Yes and no. The new window should automatically take up the existing session, but there is a bug in Internet Explorer (v5?) where it creates a new session for the pop-up window. You can use url rewriting to force the second window to take up the existing session.

No there's not
There's a bug in some versions of Netscape where a new window will be a separate process thus a new session, not in IE (at least not in any 5.x or 6.x version, maybe in very old ones).
I've been programming against IE for years (since about 1999) and never encountered any problems.

It could be using cookie to keep your session id. IE don't seems like share cookies between browsers. Well IE does that to me but not Netscape and Mozilla when I use cookies based authentication.
