jchart - struts - image map

Hi All,
 
I am trying to use jchart with Struts.  I can generate multiple graphs
on a single JSP page now (without Struts).  But I am not sure how to
integrate it within Struts.  Also, how can I include the generation of
image map (2 steps process) in Struts as well.
 
Any suggestions are welcome.  Thanks in advance.
 
thanks,
Carina
