Charting Portlet using JSR-286
A while ago I had written an SDN article on how to generate charts dynamically in portlets. Following up on that, I have created a portlet that uses the JSR-286 feature of serve resources, to dynamically generate charts by reading its data from a JDBC compliant database. The essential feature of this portlet is that the image is generated dynamically and served via a serve resource call and isn't stored in any temporary location. The portlet can be run under any portlet container that supports JSR-286 specification. It has been tested on OpenPortal Portlet Container which supports the draft 19 of the JSR_286 specification. You can download the portlet war file from here.

That's great. Please contribute this portlet to portlet-repository.dev.java.net

I've got this message:
No Chart Configured - Use Edit Mode.
Can I get all your source codes with description to install (+ MySQL)?
Thank you very much !

Please visit my personal blog, the link to which is on the right hand side. There I have listed where you can get hold of the source code.
Also for the problem you are facing, log into the portal, and then the edit mode of the portlet will be visible to you. There you can configure the portlet for the type of chart you want.
The reason is that the same portlet can be configured differently by each user, and hence the preference of what type of chat the user wants to see is saved as part of that users preference, which can only be done when the user has logged into the portal
The location where the source code lives, there is also documentation on how to get the portlet to work from start.

Hi!
I've paied for supporting JFreeChart_Developer_Guide, souce codes USD 48.75.
Total Payment Received NOK 267.42 (Norway)
I am studing now how I can use this project to start JFreeChart application from my database MS SQL and JFreeChart portlets from JFreeChart appl too.
I want to pay for your short application too with source codes that can start correctly in JSR 286.
This obtained portlet - example can start just in JSR 186. http://cld.blog-city.com/three_new_articles__dynamic_charting_in_portlets_sorting_jli.htm
It doesn't help me too.
