JFreeChart 0.93 - New Servlet / JSP Features

[Richard Atkinson]

There are several new features in Version 0.9.3 that are designed for use in a servlet / JSP environment. The new features include:

1. Charts with tooltips (previously possible only in non-servlet environments)
2. Charts with drill down capabilities using custom URLs
3. Utility classs to simplify persisting charts into the temporary directory
4. Generic servlet to stream charts created in the temporary directory to the user that created them
5. Automatic deletion of charts that were created by users whose sessions have expired or have been explicitly abandoned

I have put together a WAR file to demonstrate the new facilities and it is available at http://homepage.ntlworld.com/richard_c_ ... jfreechart

Dear Richard,

I am from China, the date format is YYYY-MM-DD, when I run the demo, I couldn't see the result, because the webserver said that cann't parse the date format "01-Aug-2002".
How can I see the currect result?

Thank you.

Liu,

I must admit I didn't think I had any default SimpleDateFormats in the source but had instantiated them all to use dd-MMM-yyyy, to avoid differences in default locales. However it is possible that I have missed some.

My recommendation would be to download the source (there is not very much of it) and modify the part that is failing. It would probably be easier for you to track down the problem than it is for me. If there are any generic modifications that you feel should go back into the original, please let me know.

Thanks and regards,
Richard...
