What I usually do is something like this (note: I'm using Struts and
JSTL): I pass the command string to an Action that puts the search
results (or whatever, read: dynamic data ) in request scope and
forwards to a JSP (the View part) that just takes the results and
displays that.
Though I usually tend to steer clear from JavaScript, for popup windows
I found it to be just necessary, so I put something like this into the
originating page:
<script>
<!--
function popup(targetURL) {
var props =
"scrollBars=yes,resizable=no,toolbar=no,menubar=no,location=no,directories=no,width=400,height=400";
var popup = window.open(targetURL, "Details", props);
popup.focus();
//-->
}
</script>
Then, I invoke the Action from that page by something like this:
<a href="javascript:popup('<c:url value="/showDetails.do"><c:param
name="id"><c:out value="${current.id}"/></c:param></c:url>')">
The Action now talks to the model, does whatever is possible in Java and
adds the results to the request (sorry for the crappy formatting):
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) throws
IOException, ServletException {
int id =
ServletUtilities.stringToInt(request.getParameter(Constants.SC_PARAM_ID));
CustomerBean cb = PersistenceFacade.getInstance().getUserDetails(id);
request.setAttribute(Constants.SC_CUSTOMER_BEAN_TOKEN, cb);
return mapping.findForward(Constants.SC_SUCCESS);
}
In struts-config.xml, the mapping for the successful scenario finally
forwards to a page that displays the final results. This page just
takes the information passed and displays that in the popup window
created by the JavaScript part (using JSTL), which was invoked via the
link. Should not make any real difference here if you're using POST and
forms instead of mere links or don't make use of Struts at all; even if
you have to deal with several submit buttons, you may tell them apart
from each other because the one the user finally presses ends up as a
parameter (so better keep heed of the 'name' property) in your request.
If you need further help, just send me a mail :-)
