Yes this is actually one thing that is very easy to do. Just have an ajax
updater function make a request to one of your event handler methods, and
return a forward resolution to your jsp. The jsp will surprisingly just get
processed and inserted into your div. =)
Now if your event handler returns validation errors, that does not work at all,
and you have to write a bunch of code to make it work. Stripes really should
do much better at that.

Subject: Re: [Stripes-users] How to get JSP output as a HTML stream for AJAX?
That's quite possible, and extremely common. The server-side (Stripes) code
really doesn't need to know that it's responding to an AJAX request; it just
forwards to the JSP as usual. The client-side code just does exactly what you
describe with the new content.
Using a client-side framework (Dojo, Prototype, jQuery, whatever) makes this
considerably easier.

I hope I'm not asking a dumb question or one that's been answered a hundred
times, I probably don't know the right search terms, but if anyone has any
pointers to answer my question it is gratefully accepted! I've been happily
using Stripes for the past few months, but I'm not sure if this is strictly
a Stripes question.
I am wondering if it's possible to render a JSP from within Javascript, such
as sending a request to the server and getting the rendered HTML stream
back, which I can dynamically display.
Here's how my current web page is set up:
<div id="customer"><jsp:include page="/customer_info.jsp" /></div>
<div id="specs"><jsp:include page="/widget_specifications.jsp" /></div>
<div id="disclaim" ><jsp:include page="/boring_legal_disclaimer.jsp"
/></div>
<div id="order"><jsp:include page="/complicated_order_form.jsp" /></div>
Changing one of these JSP files sometimes makes it necessary to change the
information on another JSP. I am doing an Ajax submit of the Stripes form,
which updates the database with no problem. However, the user display isn't
up to date.
I could do this easily with a servlet, getting all the HTML myself, but
bleh, all the JSPs are already written and they all work great. The JSPs are
fairly complex so it's not really feasible to write some Javascript to do
the updates without pretty much duplicating the entire JSP code in
Javascript.
So can I do this:
1) User updates their personal information in "customer_info.jsp", database
updates (this step works A+)
2) Ajax Call: request "complicated_order_form.jsp" rendered into HTML, with
new db values
3) Dynamically put the received HTML into the innerHTML() of the "order" div
Again, apologies if this has been answered a million times, I tried to do my
homework, honest! On the other hand, if what I'm trying to do with the JSPs
is simply impossible, what other strategies might be better?
Thanks!
