Re: Displaying image on T5 page
Hi Yeeswar, I recently had exactly the same requirement, and solved it in the same way referenced in the wiki page. So then I rewrote my solution as a "DisplayChart" component, which takes a chart as a parameter and handles the rest of the work for you. A few notes/comments, though: 1) In my case, the chart wasn't generated from parameters in the url, per se. So I initially had problems with the browser caching the chart image because even though the chart had changed, the url was the same. I solved that issue by generating an identifier key for the chart that ensures that different charts get different urls. 2) I create the byte array outside of the StreamResponse. That way I can set the content length (and any other properties I want) in "prepareResponse" 3) The Wiki article uses jpeg compression. PNG is better for charts, and just as easy to do with the JFreeChart API. If you're interested in my "DisplayChart" code, write me off list and I'll send it along.

RE: Displaying image on T5 page
Hi Sven, This will only work when the mychart.jpg already exists at that specified path. But, as per my requirement I have to generate the JPG dynamically and show it on the page. I got a reference at http://wiki.apache.org/tapestry/Tapestry5HowToCreateASimpleGraphComponen t But, it doesn't help much with my requirement.
