I checked the SVN activity for cewolf, there were lots of reads, few writes in 2006 but very little activity in 2007.

We have used CeWolf, and it is quite good, but based on the last release date and the fact that the newer versions of JFreeChart seem to be not supported, I wonder if the CeWolf project is moribund. Another solution I used several years ago is to store the JFreeChart 'Chart' object in the Session, and then use a special Servlet to get the Chart object and to output a png or jpg image object. An image referenced in a page with an href always causes a separate request cycle to serve the content. Although this required a separate servlet, there were probably only 10 lines of code in it. Another solution is to output the image in svg format or to output it in a binary byte stream as a multi-part request. The really nice feature of CeWolf, which none of these other methods have is that CeWolf had image-mapped tool tips to give the coordinates of important features. I wonder if this project is still alive in any meaningful way.
