Subject Re: Getting window size

Hi Gonzalo,

AFAIK, there's no portlet standard way to retrieve the portlet window size currently.
However, if you have a chance to use client side script before retrieving the size info from
your server-side code, then you can depend on Jetspeed specific html markups.
Most Jetspeed layout templates write a div tag for each portlet window with setting the id
of the div tag to the portlet window id.
For example, you can find html tags of a portlet window in a portal page like this:

<div id="dp-7" class="portlet jetspeed">
  <div class="PTitle">

  <div class="PContentBorder">


To find the portlet window id with Jetspeed-2 api, you can code like this:

import org.apache.jetspeed.request.RequestContext;
import org.apache.jetspeed.container.PortletWindow;
RequestContext rc = (RequestContext) renderRequest.getAttribute(RequestContext.REQUEST_PORTALENV);
String windowId = rc.getCurrentPortletWindow().getWindowId();

By the way, I've searched on the internet about how to detect the size of div tag with javascript
and some people recommend to use 'div.offsetHeight' and 'div.offsetWidth'.

Hi Gonzalo,

I don't have a ready answer right now for retrieving the current portlet window size, but
I'll talk to Woonsan today to see if his auto-resizing IFrameProxyPortlet might contain some
features which you could leverage and I or Woonsan will come back on this.

Besides that, I'm very interested to know how you are using BIRT from within a portlet.
I have a feature request for a client for which I'll need to provide a BIRT reporting engine
*manageable* from within Jetspeed as a general reporting service. My intention is to create
a generic solution to be hosted under Apache Portals Applications, so it might be usable even
for other portals as well...

If you already have something setup for this which you are willing to share and/or provide
some insight in how you've using BIRT would be very great!
