i want to show simple charts in JSPs with the JCharts library.
I already know how to generate them in a Servlet.
So if I open this servlet directly it displays the chart in the correct way. I just want to generate the chart in the servlet and then add it to the JSP. But how do I do that? I mean I can´t use getProperty like if I want to get a string so how can I access the encoded chart within the JSP?
You would save the image to a publicly accessible place in the file system, and then add a link to that file to your JSP.

Thanks for your fast answer Tim :-)
I will try it but will the image be in the filesystem forever or is it just temporary for this session maybe? I mean if a lot of users want to see charts then there would be so many files in the file system.

If this was my problem I'd check out the cewolf tag library, which integrates chart generation and chart display with a JSP tag library. It can be set up to remove outdated images automatically (and also cache them, in case users request the same images over and over again).
