The purpose for this simple package is to allow anyone to render complex charts using a Java Servlet. Although this is simple enough using JFreeChart the issue is that no-one has released such a product: This means that anyone using a Java Servlet engine has to code his own. The product was primarily written to allow Warfare to render charts from data sources, which as a tool kit is specifically design for people with no programming knowledge.

The Road To Stability

For too long now JWebChart has been stagnant on Sourceforge, but has been living on my latop in a re-factored form. So I thought it was about time that I released the stable code base and reflected the changes in the CVS repository. Whilst doing this I thought that I really should upgrade to the latest version of JFreeChart and JDK - so I did this too. Let me know how the changes go and if you like what I have done. Doing this has got me all ready to release another version...

How Does It Work?

The code is a simple servlet that takes all the parameters it needs to render the specified chart and thus allows it to be plugged into any web application. For example: http://localhost:8080/jwebchart/ChartServlet? Series=Pie&Type=3D&Title=Developer%20Preference& Java=55&C=47&VB=78&Cache=10

will render a 3D Pie chart with the specified data.

Great Minds Think A Like

For a long time JWebChart was the only charting servlet that I had found that was Open Source and worked in the way that it does. It appears that now there is a new kid on the block in the form of Google Charts API. This has got to be a good thing in my eyes - the Google Chart API works on the principle that you web pages online will access the Google services (of which I am a great fan). More people will start to think of charting on their webpages in this way and will want something on their internal networks to perform in a similar way.

The next release is in design/development. I am working on another big change to the functionality that once complete I am going to be pretty happy with. Keep coming back to see where I have got to with it.
