Thank you for reading my post.
I have a big problem for showing Charts in my jsf portlet , there is no 
library to use.
so i come to this idea to make a web service and , the web service take 
parameters and create chart using Jfree, .... .
and then web service return the chart to my jsf portlet . i can use that 
chart and show it to my visitors.

now my question is :
1-How i can return an image with a web service ?
2-how i can show that image ?


Do you know better way to generate chart and show it in a jsf portlet page ?


Thank you for your help.
