This week's book giveaway is in the Agile and other Processes forum. We're giving away four copies of The Mikado Method and have Ola Ellnestam and Daniel Brolund on-line! See this thread for details.
i have started using a small supporing code which can display charts in your web application, and it is called cewolf.
Now, the problem is i have used exactly same JSP tags that are to be used to render a chart, but i couldn't display them.. does anyone have an idea on this cewolf??
please pour in your thoughts
Thanks

Welcome to JavaRanch.
Which problem are you facing exactly? Have you been able to get the tutorial code to run on your machine?
yeah, i have followed the steps given there. But the problem comes in where i want to define my own charts. I have followed the tutorial and i pasted the same code in my application also.. but the chart is not been rendered

So .... that means the JSP is rendered correctly, but the image isn't? Are there any error messages in the server logs?

yes exactly, and there are no error messages too. It is something like this
when i change the parameters to render a new graph, the same old page is being displayed and the changes are not reflected in the new graph

So the image is in fact being rendered, but it's not changing when you change some parameters. How are you changing parameters - is that a change to the JSP page, or in Java code, or someplace else?
