I'm trying to make a JSR-168 portlet with a chart. Studying about it i can run some portlets in NetBeans with portlet-container but i have to make some charts to run too. Can some one help with a LINK or an Example? I found that to help me:
-> dojocampus.org -> dojotoolkit.org -> extjs.com
I make a chart, but when i put on portlet-container have the error: "Deployment Failed Portlet war file. Possible reason can be error reading WEB-INF/portlet.xml from portlet war file". Only the portlet or the chart they work, but toghetter make the error. JSR can run any chart type(flash, Java Script, etc)?

The easiest(even not perfect) way is to create a ordinary servlet which receives the values as input parameters and output would be the picture.
Here is some basic info how to create dynamic image in servlet: http://www.exampledepot.com/egs/javax.servlet/GetImage.html
To generate image of graph you can use this library: http://www.jfree.org/jfreechart/index.html
