Hey all
is it possible to forme my struts app to open up a second browser window for
the purpose of streaming a different content type (like a pdf file) into it
while maintaining the page in the original browser?
Essentially, I have a nicely rendered HTML report in browser a and when
the user
David,
You could have your response return HTML with rendered JavaScript; the
script would then automatically pop open a new window with the destination
link that generates your unstructured content. You could even provide a link
in the response if the JavaScript doesn't run automatically.
hmm I dont think I understand. so instead of redirecting to an action
mapping, just add the HTML myself, like you would if you were writing a
servlet (no jsp) application? interesting.
you're right, I dont need a nice tiles definition page for my pdf/xls
output.. all I really need is to pop up
David,
You cannot control opening a new client window from a server response. This
is all client-side control -- javascript for the user explicitly opens a
link in a new window. Because of this limitation, you need to work with the
client-side support that you may have control over: JavaScript.

the user clicks export to PDF or export to excel I want a NEW browser
to pop up into which I will send the response with the headerType set to
the appropriate type.
Without an applet or ActiveX control or something
Hi Dave,
This is pretty straightforward. In browser a, you have a button that says:
Export to PDF
The code would look like this:
html:form action=/exportToPdf.do target=_NEW
submit name=export value=Export to PDF
/html
When the user clicks on the button, the action exportToPdf.do opens an
A, gotcha. it's an internal app thankfully, and they're fine with
javascript.
The report itself foesnt exist when the page is sitting there rendered. the
action is going to render it.. a Call to SAS specifically, --
whoa that's simple. I'm trying that first Thanks
One things though, I'll have to set the target conditionally, only when
the user clicks PDF or EXCEL since I dont **always** want it opening a
new window...
function setTarget(target) {
document.forms[0].target=target;
}

David,
Aladin has a more straight forward approach. If you can know ahead of time
when you need to open a new window, take his approach; if you have no prior
knowledge, you'll need to send back JavaScript to open a new window. Either
way should fit the bill.
Thanks,
Paul

Ugh, I always forget the simple target attribute! Absolutely agreed,
that's probably the best approach.

Return null.
Returning null means you have handled the response and Struts will do no
more.

Wow, excellent. Thanks! is tehre anything IU need to do to close my
PrintWriter in the Action class? right now I have
response.setContentType(application/pdf);
response.setHeader(Content-disposition, inline );
PrintWriter out = response.getWriter();
socket.write(out); // I get my PDF through
Return null. That's it (seriously!) Null effectively means do not
forward to anything, the response is completely formed.

As a general rule you always want to close any stream when done, unless
you know by design that you need it to remain open, so yes, you probably
want to close it.
That being said, I've seen *PLENTY* of code that does things like this
that don't close the stream, and as far as I could tell it
